Mass culture of Azotobacter
This genus has a wide variety of metabolic abilities, including the unusual ability to fix atmospheric nitrogen by converting it to ammonia. Most nitrogen-fixing bacteria (typically members of the genus Rhizobium) form symbiotic associations with leguminous plants, where they are provided with nutrients by the plant and simultaneously protected from oxygen, which poisons the enzyme required for nitrogen fixation (nitrogenase). Azotobacter (and a few other species of bacteria such as Klebsiella pneumoniae) are free-living in soil and water and do not form symbioses. So how do they do it? Like other nitrogenases, Azotobacter nitrogenase is oxygen-sensitive, but it is believed that the extremely high respiration rate of Azotobacter (possibly the highest of any living organism) soaks up free oxygen within the cells and protects the nitrogenase.

Culture of Azatobacter
Mother culture: A pure growth of any organism on a small scale is called as a mother culture. Mother culture is always prepared in a conical flask of 500 or 1000 ml. Capacity and then this mother culture is used for further production.
For this purpose, one litre conical flasks are taken to which 500 ml of broth of nitrogen free medium is added and these flasks are then plugged with non-absorbent cotton, sterilized in an auto slave for 15-20 minutes at 75 lbs pressure for 15 minutes. Flasks are then inoculated with mother culture with the help of inoculating needle aseptically. The flasks are transferred to shaker and shaking is done for 72-90 hours so as to get optimum growth of bacteria in broth. Bacteria are multiplied by binary method i.e. cell division. After about 90 days, the number of per milliliters comes to about 100 crores. Total growth of bacteria in this broth means starter culture or mother culture, which should carefully be done, since further purity of biofertilizer or quality of biofertilizer depends upon how mother culture is prepared.
Production on a large scale: Azotobacter is multiplied on a large scale by two ways viz. Fermenter and Shaker. The fermenter is most automatic and accurate method of multiplication of any micro-organism. In this method, the medium is taken in a fermenter and then sterilized. After this pH of the medium is adjusted and 1% mother culture is added. In order to get an optimum growth of the Azotobacter required temperature and oxygen supply is adjusted so that concentrated broth is made. This concentrated broth of the culture is then mixed with a carrier previously sterilized and bio-fertilizers is prepared. Depending upon the demand and supply suitable fermenter is selected.
Media for Azatobacter
Acetobacter Agar (Glucose) is used as a maintenance media for glucose positive Acetobacter species.

Mass culture of Azolla
Azolla (Azolla sp.) is an aquatic fern consisting of a short, branched, floating stem, bearing roots which hang down in the water. The leaves are alternately arranged and each consists of a thick aerial dorsal lobe containing green chlorophyll and a thin floating ventral lobe of slightly larger size that is colourless. Under certain conditions, an anthocyanin pigment gives the fern a reddish-brown colour. Plant diameter ranges from 1-2.5 cm for small species, such as Azolla pinnata, to 15 or more cm for Azolla nilotica. Azolla plants are triangular or polygonal in shape, and float on the water surface individually or in mats. They give the appearance of a dark green to reddish carpet, except Azolla nilotica which does not produce the red anthocyanin pigment. The most remarkable characteristic of azolla is its symbiotic relationship with the nitrogen-fixing blue-green alga (cyanobacterium) Anabaena azollae. The fern provides nutrients and a protective cavity in each leaf to Anabaena colonies in exchange for fixed atmospheric nitrogen and possibly other growth-promoting substances.
Figure: Azolla
Mass multiplication of Azolla under field conditions
A simple Azolla nursery method for large scale multiplication of Azolla in the field has been evolved for easy adoption by the farmers.
Materials
- One cent (40 sq.m) area plot
- Cattle dung
- Super phosphate
- Furadan
- Fresh Azolla inoculum
Procedure
- Select a wetland field and prepare thoroughly and level uniformly.
- Mark the field into one cent plots (20 x 2m) by providing suitable bunds and irrigation channels.
- Maintain water level to a height of 10 cm.
- Mix 10 kg of cattle dung in 20 litres of water and sprinkle in the field.
- Apply 100 g super phosphate as basal dose.
- Inoculate fresh Azolla biomass @ 8 kg to each pot.
- Apply super phosphate @ 100 g as top dressing fertilizer on 4th and 8th day after Azolla inoculation.
- Apply carbofuran (furadan) granules @ 100 g/plot on 7th day after Azolla inoculation.
- Maintain the water level at 10 cm height throughout the growth period of two or three weeks.
- Observations
- Note the Azolla mat floating on the plot. Harvest the Azolla, drain the water and record the biomass.
Application
Weed
Because azolla can form dense mats on water surfaces, it is classified as a water weed in many areas. It has been reported to disrupt fishing and livestock watering, clog pumps, impede water flow in ditches, clog pipes and floodgates, and interfere with watercress cultivation.
N-fixation and green manure
The main reason for the enduring popularity of azolla among agriculturists is its N-fixation, which allows it to be used in paddy fields under waterlogged or flooded conditions where N-fixating legumes cannot grow, or to be used as green manure for upland rice growing on the most fertile soils that farmers are reluctant to use for legume crops. .
Limitation of N volatilization
By reducing light intensity underwater, azolla inhibits algae photosynthesis and the subsquent pH increase and NH3 volatilization.
Weed control
Azolla suppresses the growth of certain aquatic weeds by forming a thick mat that deprives weed seedlings of sunlight while preventing them mechanically from emerging.
Mosquito control
The ability of azolla to prevent mosquito breeding and thus the spread of paludism was suggested in the early 20th century (hence the name "mosquito fern"). It did not prevent oviposition of Anopheles sinensis but limited the emergence of adult insects.
Bioremediation
Azolla can hyperaccumulate pollutants such as heavy metals, radionuclides, dyes, pesticides etc. For that reason, it is used for the bioremediation of waste waters and effluents. Reclamation of saline soils and the production of biogas and bioenergy.
Integrated farming systems
Numerous integrated farming systems have been designed where combinations of azolla, rice (or another crop), fish, ducks and pigs can complement each other.
Harvesting
• Will grow rapidly and fill the pit within 10 - 15 days. From then on, 500 - 600 g of azolla can be harvested daily.
• Can be done every day from the15th day onwards with the help of a plastic sieve or tray with holes at the bottom
• The harvested azolla should be washed in fresh water to get rid of the cow dung smell

Mass culture of Rhizobium
Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium forms an endosymbiotic nitrogen fixing association with roots of legumes and Parasponia. The bacteria colonize plant cells within root nodules; here the bacteria convert atmospheric nitrogen to ammonia and then provide organic nitrogenous compounds such as glutamine or ureides to the plant. The plant provides the bacteria with organic compounds made by photosynthesis. Bacteria of the genus Rhizobium play a very important role in agriculture by inducing nitrogen-fixing nodules on the roots of legumes such as peas, beans, clover and alfalfa. This symbiosis can relieve the requirements for added nitrogenous fertilizer during the growth of leguminous crops. The Rhizobium group is studying the bacterial and legume genes involved in establishing and maintaining the symbiosis.
Figure: Rhizobium
Culture of Rhizobium
Cultures were grown from single colonies inoculated in 16 x 100 mm test tubes with 4 mL of YEM broth devoid of mannitol and incubated at 28º C for 3 days in the case of Rhizobium strains and 5 days for the Bradyrhizobium strains. This culture was diluted to 10-2 with 0,85% saline solution and 0,1 mL of this dilution served as inoculum for tubes (10 x 75 mm) containing 1,6 mL of modified media. Tubes were vigorously shaken every 12 hours to minimize O2 stress. Growth was determined by plate counts on YEM agar when cultures reached the late log phase
Rhizobium medium
Directions
Suspend 31.8 grams in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Mix well and pour into sterile Petri plates.
Principle And Interpretation Rhizobium Medium is used in the large scale production of legumes and in their isolation from root nodules. Rhizobium Medium is recommended for isolation and cultivation of mannitol-positive Rhizobium species. It is also useful for the maintenance of Rhizobium species by adding extra 1% mannitol to the medium as specified by the American Type Culture Collection (1). The medium is well buffered for pH changes and osmotic changes by presence of phosphate and sodium chloride salts. Yeast extract provides nitrogenous nutrients. Mannitol is the energy source while magnesium sulphate provides essential ions. The inocula are transferred from agar slants into starter flasks containing Rhizobium Medium. After 4 days of growth, the culture from starter flasks is transferred into a small seed tank fermentor. At this stage, Rhizobium Medium is used for large scale production. Rhizobium may be isolated from the root system of the leguminous plant. The healthy, pinkish nodule on the tap root is carefully cut out. The nodule is surface sterilized for 5 minutes and then washed with solvents like ethanol etc. The nodule is then crushed with a sterile glass rod in a small aliquot of sterile water. Serial dilutions are subsequently made to get sparse and distinct colonies. The dilutions are plated on Rhizobium Medium and incubated for upto 4 days at 25-30°C.

Mass Culture of Spiruluna
Spirulina is a cyanobacterium that can be consumed by humans and other animals. New understanding of its genetics, physiology and biochemical properties caused scientists to move it to the bacteria kingdom, in the genus Arthrospira at first, and later into the genus Spirulina. There are several species, but three — Spirulina platensis, Spirulina maxima and Spirulina fusiformis — are studied extensively because of their high nutritional as well as potential therapeutic values. When harvested correctly from non-contaminated ponds and bodies of water, it is one of the most potent nutrient sources available. It is largely made up of protein and essential amino acids, and is typically recommended to vegetarians for its high natural iron content. It is often touted for its high B-12 content, though there is a lot of debate about if this particular form is a complete and absorbable form of B-12 and I don’t recommend it completely in place of animal products.

Figure: Spirulina
Application
Immune Support: Spirulina increases production of antibodies, infection-fighting proteins, and other cells that improve immunity and help ward off infection and chronic illnesses such as cancer. However, it has not been tested in people. In one clinical trial that involved humans, another type of blue-green algae called chlorella did not boost the immune response to flu vaccine.
Protein Supplement: Amino acids make up 62% of spirulina. Because it is a rich source of protein and other nutrients, spirulina has been used as a nutritional supplement. However, although spirulina contains a certain level of protein, you would need to take very large quantities to see any effect. Other sources of protein, such as nuts, legumes, whole grains, and meat, provide protein in smaller servings.
Allergic Reactions: Spirulina may protect against allergic reactions by stopping the release of histamines, substances that contribute to allergy symptoms, such as a runny nose, watery eyes, hives, and soft-tissue swelling.
Antibiotic-related Illnesses: Although antibiotics destroy unwanted organisms in the body, they may also kill "good" bacteria called probiotics, such as Lactobacillus acidophilus. This can cause diarrhea. In test tubes, spirulina has boosted the growth of L. acidophilus and other probiotics.
Infection: Test tube studies suggest that spirulina has activity against herpes, influenza, and HIV. But researchers don’t know whether it would also work in people.
Oral Cancer: Spirulina seemed to reduce a precancerous lesion known as leukoplasia in people who chewed tobacco. Lesions were more likely to go away in the spirulina group than in the placebo group.
Liver Disorders: Spirulina may help protect against liver damage and cirrhosis (liver failure) in people with chronic hepatitis.
Dietary Sources: Spirulina is a microscopic algae that flourishes in warm climates and warm alkaline water. It is available dried and freeze-dried.
Cultivation of Spirulina
The commercial design Spurulina culture system comprise a network of cement raceways with paddle-wheel agitation to prevent algal accumulation at the surface and to ensure uniform distribution of nutrients with modifications in terms of vertical reactors, tubular reactors, sloping tanks with baffles, etc. The outdoor cultivation parameters are cement raceways of vats (length-breadth ratio 1:5:1)preferably with a mid-rib for facilitating water circulation, culture medium depth 15-20 cm, agitation/flow rate 20 cm/sec, temperature 25-350c, light intensity 20-30 klux, hard ness 120 mg/l, PH 9-11, provided with nutrients.

Mass culture of Tricoderma
Trichoderma spp., are free-living fungi that are common in soil and root ecosystems. They are highly interactive in root, soil and foliar environments. They produce or release a variety of compounds that induce localized or systemic resistance responses in plants. Trichoderma strains have long been recognized as biological agents, for the control of plant disease and for their ability to increase root growth and development, crop productivity, resistance to abiotic stresses, and uptake and use of nutrients.
Figure: Tricoderma
Culture media
Storage
Contains live organisms. Do not mix with biocides. Store in cool, dry place away from sunlight. Shelf-life – 1 year from manufacture date (unopened). May be stored in a refrigerator after opening for up to 3 months. However, contamination may occur once opened. Gloves and breathing mask should be worn at all times when handling microbial products.
Application
Disease Control: Trichoderma is a potent biocontrol agent and used extensively for post-harvest disease control. It has been used successfully against various pathogenic fungi belonging to various genera, viz. Fusarium, Phytopthara, Sceleroti.a
Plant Growth Promoter: Trichoderma strains solubilize phosphates and micronutrients. The application of Trichoderma strains with plants such as grasses increases the number of deep roots, thereby increasing the plant's ability to resist drought.
Biochemical Elicitors of Disease Resistance: Trichoderma strains are known to induce resistance in plants. Three classes of compounds that are produced by Trichoderma and induce resistance in plants are now known. These compounds induce ethylene production, hypersensitive responses and other defence related reactions in plant cultivates
Transgenic Plants: Introduction of endochitinase gene from Trichoderma into plants such as tobacco and potato plants have increased their resistance to fungal growth. Selected transgenic lines are highly tolerant to foliar pathogens such as Alternaria alternata, A. solani, and Botrytis cirerea as well as to the soil-borne pathogen, Rhizectonia spp
Bioremediation: Trichoderma strains play an important role in the bioremediation of soil that are contaminated with pesticides and herbicides. They have the ability to degrade a wide range of insecticides: organochlorines, organophosphates and carbonates
Production
Biological suppression of plant pathogenic fungi has been dominated by use of Trichoderma spp all over the world for last 2-3 decades. Trichoderma spp. act as a biofungicide against many plant pathogenic fungi and have been found to induce systemic resistance in plants. The field applications of Trichoderma spp. require mass multiplication which can be done using solid as well as liquid state fermentation. In the industrialized nations, liquid fermentation is extensively used for multiplication of Trichoderma spp. for commercial formulation. However, solid state fermentation is preferred in developing countries like India due to low initial investment as well as availability of cheap labour and space. Presently, solid state fermentation technology uses food grains including sorghum and bajra for commercial mass multiplication of Trichoderma spp at an industrial scale. However, the food grains are comparatively expensive, have short storage life and may not be available freely due to climatic stress. Thus there is an urgent need to develop a formulation based on easily available material and with lower input cost. We have developed a low cost mass multiplication medium for faster growth of Trichoderma spp. This material supports better growth of biofungicide compared to existing methods and addition of synthetic sticker is not required while making its formulation. Another advantage is that this material can be used for both solid as well as liquid fermentation. This material provides longer shelf life of the biofungicides and also improves the resistance of the plant against diseases. The process is cheaper than the existing methods and is based on the material which is inexpensive and available locally. This technology will thus be a boon to the biopestcides industry based on Trichoderma spp.

Vermicomposting
Vermicomposting is the process of producing organic fertilizer (vermicompost) using agricultural wastes through the digestive action of earthworms. It is a promising technique that has shown its potential in certain challenging areas like augmentation of food production, waste recycling and management of solid wastes etc. It helps to avoid the environmental pollution and expenditure of resources to treat the organic waste.
Vermicompost improves soil texture and enhances water-holding capacity of the soil. It may be low in NPK but contains essential nutrient (e.g. calcium, magnesium, manganese, copper, iron and zinc) not found in inorganic fertilizers. Moreover, it has microbial activities that promote plant health and pest/disease resistance. With the abundant source o f material in farms, vermicompost can help protect the environment, promote and sustain soil productivity and generate livelihood opportunities for rural families.
Technique

Mushroom
1. Introduction
The word mushroom may mean different things to different people and countries. In a more broad sense “mushroom is a macrofungus with a distinctive fruiting body, which Mushrooms along with other fungi are something special in the living world, being neither plant nor animal. They have been placed in a kingdom of their own, called Myceteae. In a more broad sense “mushroom is a macrofungus with a distinctive fruiting body, which can be either epigeous or hypogeous and large enough to be seen with naked eye and to be picked by hand”. Mushrooms can be Ascomycetes, grow underground, have a nonfleshy texture, and need not be edible. The most common type of mushrooms is umbrella shaped with a pileus (cap) and a stipe (stem), that is, Lentinula edodes. Other species additionally have a volva (cup), that is, Volvariella volvacea, or an annulus (ring), that is, Agaricus campestris, or both, that is, Amanita muscaria. Furthermore, some mushrooms are in the form of pliable cups; others are round like golf balls. Some are in the shape of small clubs; some resemble coral; others are yellow or orange jellylike globs; and some even very much resemble the human ear. In fact, there is a countless variety of forms.
2. Cultivable edible mushroom in India
In India, mushroom is a unique non-traditional cash crop grown indoors, both as a seasonal crop and round-the-year under the controlled environmental conditions. About 2000 species of fungi are used as food by tribes and various communities, however, only a few are cultivated. Climatic conditions in India are favourable for natural occurrence of mushrooms and some of them are regularly collected and used as food by the natives particularly those belonging to tribes. The common mushrooms collected from nature are species of Astraeus, Auricularia, Calvatia, Cantharellus, Lycoperdon, Morchella, Schizophyllum, Termitomyces, Tuber etc.
Three mushrooms are commonly cultivated throughout India namely button (Agaricus bisporus), Oyster (Pleurotus spp.) and paddy straw mushroom (Volvariella volvacea). Their ability to grow on agricultural wastes in less area required for cultivation makes an attractive proposition for income generation. The added advantage is in improvement in dietary leading to solution to malnutrition, pollution abatement and diversification of agriculture. Mushroom cultivation produces about 32 tons of dry protein per year in per acre of land while by fish farming only 3 quintals of proteins can be produced. The agriculture wastes which are burnt and cause environmental pollution, if can be used for mushroom cultivation will not only check pollution but will also play an important role in carbon sequestration and proper utilization of waste products.

3. Naturally available edible mushroom
However the forest provides large and diverse varieties of wild edible mushrooms. Macrolepiota procera (Scop.) Singer, Termitomyces clypeatus R. Heim, T. albuminosa (Berk.) R., T. heimii K. Natarajan, Boletus edulis Bull and some are commonly collected and consumed wild edible mushrooms. They are rich in protein and can easily fit into all's platter, being a vegetarian product.
4. Techniques of cultivation
The whole process of mushroom production can be divided into the following steps:
(i) Spawn production
(ii) Compost preparation
(iii) Spawning
(iv) Spawn running
(v) Casing
(vi) Fruiting
(i) Spawn Production
Spawn is produced from fruiting culture / stocks of selected strains of mushrooms under sterile conditions. Stock culture may be produced in the lab or may be obtained from other reputed sources. Fruiting culture is mainly imported from various places including foreign sources which give higher yield than Indian strains and the spawn is produced in the lab. The spawn should be of good quality in terms of flavour, texture and size apart from having potential for high yield and longer shelf life
(ii) Compost Preparation
The substrate on which button mushroom grows is mainly prepared from a mixture of plant wastes (cereal straw/ sugarcane bagasse etc.), salts (urea , superphosphate / gypsum etc), supplements (rice bran/ wheat bran) and water. In order to produce 1 kg.of mushroom, 220 g. of dry substrate materials are required. It is recommended that each ton of compost should contain 6.6 kg. nitrogen, 2.0 kg. phosphate and 5.0 kg. of potassium (N:P:K- 33: 10:25) which would get converted into 1.98% N, 0.62% P and 1.5% K on a dry weight basis. The ratio of C: N in a good substrate should be 25-30 : 1 at the time of staking and 16-17 : 1 in the case of final compost.
(a) Short Method of composting
During the first phase of compost preparation, paddy straw is placed in layers and sufficient water is added to the stack along with fertilizers, wheat bran, molasses etc. The whole thing is mixed thoroughly with the straw and made into a stack (almost 5feet high,5 feet wide and of any length can be made with the help of wooden boards). The stack is turned and again watered on the second day. On the fourth day the stack is again turned for the second time by adding gypsum and watered. The third and final turning is given on the twelveth day when the colour of the compost changes into dark brown and it starts emitting a strong smell of ammonia.
The second phase is the pasteurization phase .The compost prepared as a result of microbe mediated fermentation process needs to be pasteurized in order to kill undesirable microbes and competitors and to convert ammonia into microbial protein. The whole process is carried out inside a steaming room where an air temperature of 600 C is maintained for 4 hours. The compost finally obtained should be granular in structure with 70% moisture content and pH 7.5. It should have a dark brown colour, sweet unobnoxious smell and free from ammonia, insects and nematodes. After the process is complete, the substrate is cooled down to 250 C.
(b) Long Method of composting
The long method of composting is usually practiced in areas where facilities for steam pasteurization is not available. In this method, the first turning is given about six days after preparation of the substrate for composting. The second turning is given on the tenth day followed by third one on the thirteenth day when gypsum is added. The fourth, fifth and sixth turnings are given on the sixteenth, nineteenth and twenty-second day. On the twenty-fifth day the seventh turning is given by adding 10% BHC (125 g.) and the eighth turning is given on the twenty-eighth day after which it is checked whether there is any smell of ammonia present in the compost. The compost is ready for spawning only if it doesn’t have any smell of ammonia; otherwise a few more turnings are given at an interval of three days till there is no smell of ammonia.
(iii) Spawning
The process of mixing spawn with compost is called spawning. The different methods followed for spawning are given below:
- Spot Spawning: Lumps of spawn are planted in 5 cm. deep holes made in the compost at a distance of 20-25 cm. The holes are later covered with compost.
- Surface Spawning: The spawn is evenly spread in the top layer of the compost and then mixed to a depth of 3-5 cm. The top portion is covered with a thin layer of compost.
- Layer Spawning: About 3-4 layers of spawn mixed with compost are prepared which is again covered with a thin layer of compost like in surface spawning. The spawn is mixed through the whole mass of compost at the rate of 7.5 ml./ kg. compost or 500 to 750 g./ 100 kg. compost (0.5 to 0.75%).
(iv) Spawn Running
After the spawning process is over, the compost is filled in polythene bags(90x90 cm., 150 gauge thick having a capacity of 20-25 kg. per bag)/ trays(mostly wooden trays 1x1/2 m. accommodating 20-30 kg. compost) / shelves which are either covered with a newspaper sheet or polythene. The fungal bodies grow out from the spawn and take about two weeks (12-14 days) to colonise. The temperature maintained in cropping room is 23 ± 20 C. Higher temperature is detrimental for growth of the spawn and any temperature below than that specified for the purpose would result in slower spawn run. The relative humidity should be around 90% and a higher than normal CO2 concentration would be beneficial.
(v) Casing
The compost beds after complete spawn run should be covered with a layer of soil (casing) about 3-4 cm. thick to induce fruiting. The casing material should be having high porosity, water holding capacity and the pH should range between 7-7.5. Peat moss which is considered to be the best casing material is not available in India, as such the mixtures like garden loam soil and sand (4:1); decomposed cow dung and loam soil (1:1) and spent compost (2-3 years old); sand and lime are commonly used.
The casing soil before application should be either pasteurized (at 66-700 C for 7-8 hours), treated with formaldehyde (2%), formaldehyde (2%) and bavistin (75 ppm.) or steam sterilized. The treatment needs to be done at least 15 days before the material is used for casing. After casing is done the temperature of the room is again maintained at 23-280 C and relative humidity of 85-90% for another 8-10 days. Low CO2 concentration is favourable for reproductive growth at this stage.
(vi)Fruiting
Under favourable environmental conditions viz. temperature (initially 23 ± 20 C for about a week and then 16 ± 20 C ), moisture (2-3 light sprays per day for moistening the casing layer), humidity( above 85%), proper ventilation and CO2 concentration (0.08-0.15 %) the fruit body initials which appear in the form of pin heads start growing and gradually develop into button stage.
(vii) Harvesting and Yield
Harvesting is done at button stage and caps measuring 2.5 to 4 cm. across and closed are ideal for the purpose. The first crop appears about three weeks after casing. Mushrooms need to be harvested by light twisting without disturbing the casing soil. Once the harvesting is complete, the gaps in the beds should be filled with fresh sterilized casing material and then watered.
About 10-14 kg. Fresh mushrooms per 100 kg. Fresh compost can be obtained in two months crop. Short method used for preparation of compost under natural conditions gives more yield (15-20 kg. per 100 kg. compost).

5. Mushroom biotechnology
Mushroom biotechnology is concerned with mushroom products and encompasses the principles of fermentation technology, mushroom biology/microbiology, and bioprocess. The products have a more generalized or tonic effect, which in some cases may act prophylactically by increasing resistance to disease in humans from the balancing of nutrients in the diet and the enhancing of the immune systems.
(i) Non green revolution
The world population has reached over 6 billion now. It is expected to continue increasing in the twenty-first century. The amount of food and the level of medical care available to each individual, especially those in less developed countries, will decrease. Environmental pollution and greenhouse gas effects will also become a more serious problem. However, the world has an immense amount of lignocellulosic material resource that, like solar energy, is sustainable. Lignocellulosic material is a kind of biomass which is estimated to amount to 1.09x 1011 t dry matter on land annually, which consists of mainly three components: cellulose, hemicellulose, and lignin. Lignocellulose is a major component of wood and other plant materials. The world’s annual yield of cereal straws in 1999 is estimated to be 3570 x 106 t. Since such a large amount of energy is in lignocellulosic biomass (3020 EJ solar energy fixed in biomass per year), it can constitute principal objects for conversion into useful products by man’s activities.
(ii) Nutritional and Medicinal value of Mushrooms
The greatest difficulty in feeding humans is to supply a sufficient quantity of the body-building material protein. The other three nutritional categories are the source of energy (carbohydrates and fats); accessory food factors (vitamins); and inorganic compounds which are indispensable to good health.
The moisture content of fresh mushrooms varies within the range 70–95% depending upon the harvest time and environmental conditions, whereas it is about 10–13% in dried mushrooms. The protein content of cultivated species ranges from 1.75 to 5.9% of their fresh weight. It has been estimated that an average value of 3.5–4.0% would be more representative. This means that the protein content of edible mushrooms in general is about twice that of onion (1.4%) and cabbage (1.4%) and 4 and 12 times those of oranges (1.0%) and apples (0.3%), respectively. In comparison, the protein content of common meats is as follows: pork, 9–16%; beef, 12–20%; chicken, 18–20%; fish, 18–20%; and milk, 2.9–3.3%. On a dry-weight basis, mushrooms normally contain 19–35% protein, as compared to 7.3% in rice, 12.7% in wheat, 38.1% in soybean, and 9.4% in corn. Therefore, in terms of the amount of crude protein, mushrooms rank below animal meats but well above most other foods, including milk, which is an animal product. Furthermore, mushroom protein contains all the nine essential amino acids required by humans.
In addition to their good protein, mushrooms are a relatively good source of the following individual nutrients: fat, phosphorus, iron, and vitamins, including thiamine, riboflavin, ascorbic acid, ergosterol, and niacin. They are low in calories, carbohydrates, and calcium. It has also been reported that a total lipid content varying between 0.6 and 3.1% of the dry weight is found in the commonly cultivated mushrooms. At least 72% of the total fatty acids are found to be unsaturated in all the four tested mushrooms. It should be noted that unsaturated fatty acids are essential and significant for our diet and our health.
(iii) Mushroom bioremediation
This component of applied mushroom biology deals mainly with the aspects of benefits to the earth from the activities of mushroom mycelium. Environmental contamination can be ameliorated by the application of mushroom mycelial technologies.
- The use of bioconversion processes to transform the polluting substances into valuable foodstuffs, for example, the proper treatment and reutilization of spent substrates/composts in order to eliminate the pollution problems.
- The use of fungi/mushroom mycelia as tools for healing soil, called “mycorestoration,” . The processes of mycorestoration include the selective use of mushrooms for mycofiltration to filter water, mycoforestry to enact ecoforestry policy, mycoremediation to denature toxic wastes, and mycopesticides to control insect pests. Mycorestoration recognizes the primary role fungi/mushrooms play in determining the balance of biological populations.
