AB: The cultivation of V. volvacea and P. flabellatus under natural conditions was studied at the Horticultural Regional Research Station, Dhaulakuan, Himachal Pradesh, India, during 1996-98. Cultivation of V. volvacea was done during May-September (temperature range 30-42oC) and that of P. flabellatus March-April and September-October (temperature range 20-30o). V. volvacea was cultivated on paddy straw. From one bed approximately 3.5-4.0 kg of mushrooms were harvested in a month; there were 4 flushes and each flush appeared at 5-10 day intervals with an average yield of 750 g to 1 kg per flush, per bed. P. flabellatus was cultivated on wheat straw. There were 5 flushes, each appearing at an interval of 6-7 days in a cropping period of 40-45 days. From one flush an average of 400-500 g of fruit bodies were harvested.

AB:Volvariella volvacea is cultivated on substrates rich in cellulose and has been shown to produce a family of cellulolytic enzymes. A PCR-based strategy was adopted to clone genes involved in cellulose utilization, using degenerate primers designed to amplify conserved catalytic domain sequences of cellobiohydrolases (CBHs). PCR with these primers produced 2 DNA fragments (GenBank accession numbers AF156693 and AF156694, respectively) with sequence similarity to the cbhI and cbhII gene families detected in Trichoderma, Phanerochaete and Agaricus species. Full-length clones of these genes were obtained from an EMBL3 genomic library, and RACE-PCR was used to verify the presence of introns. The cbhI homologue has a coding region of 1722 bp, containing 2 introns, generating a 536 amino acid polypeptide product. The cbhII gene has a coding region of 1693 bp, containing 5 introns, and gives rise to a 470-amino acid polypeptide product. Northern and PCR analyses were used to study the expression of the genes. These revealed that transcripts of both genes were induced on medium containing cellulose, with cbhI being expressed more strongly than cbhII, but were repressed on medium containing glucose.

AB:A series of experiments on the preparation and regeneration of protoplasts from hyphal strands of Volvariella volvacea were conducted with the aim of optimizing the conditions for its efficient regeneration. One commercial (Vvc1) and two wild (EAAC-0001 and EAAC-0002) strains of V. volvacea from the Philippines were used and subjected to varying conditions to determine the most efficient means for regeneration of their protoplasts. The effects of age and type of strain, pH, type and concentration of osmotic stabilizer, enzymatic composition, treatment time, temperature, reciprocal frequency during enzymatic lysis of the cell wall, and centrifugation conditions were investigated. Results showed that the three strains of V. volvacea had varying responses in terms of yield, size, and ability of their protoplasts to regenerate into the protoplast regeneration medium. Among the three strains, EAAC-0002 had the highest rate of regeneration. The 5-day-old culture of V. volvacea, when subjected to a combination of 2% Novozyme 234 and 0.2% chitinase in 0.6 M mannitol (pH 6.0) for 3 h at 30C, 90 strokes/min and centrifuged at 1100 g for 10 min, produced an efficient yield of protoplasts with a relatively high regeneration rate.

AB:The nutritional and physical requirements for the efficient mycelial colonization of Volvariella volvacea were elucidated with the percentage mycelial colonization and density as references. This investigation was limited to the evaluation of two commercial strains (designated Vvc1 and Vvc2) and two wild strains (designated EAAC-0001 and EAAC-0002) of V. volvacea from the Philippines with the aim of providing baseline data on their physiological requirements. The four strains of V. volvacea had varying preferences for carbon. Vvc1 preferred polysaccharides (starch and cellulose), whereas Vvc2 grew luxuriantly at a relatively rapid rate in sugar alcohol (sorbitol). The two wild strains preferred starch as a carbon source. In terms of nitrogen utilization, soytone, peptone, and glycine supported efficient mycelial colonization of the four strains. The vitamin utilization test revealed that ascorbic acid, calcium pantothenate, and biotin are good sources. The mycelial growth performances of the strains were also evaluated on six dehydrated mycological media. Efficient colonization of Vvc1, Vvc2, and EAAC-0002 with dense mycelial growth was noted in mycological agar. EAAC-0001, on the other hand, grew more efficiently in malt extract agar. The Philippine strains of V. volvacea grew luxuriantly when incubated at 35C and pH 8.0 under dark and sealed conditions. Moreover, the relatively higher moisture content (70%) of the oolong tea leaf formulation favourably stimulated efficient mycelial colonization. Under optimum physiological conditions, Vvc1, Vvc2, and EAAC-0002 were fast-growing strains, whereas EAAC-0001 was a moderately growing type.

Cell proliferation was decreased by VVL doses of 0.32-4 M, with S180 cells being the most sensitive. When S180 cells were incubated for 48 h with VVL at 0.32-0.8 M, prominent blebs on the cell surface and large vacuoles in the cytoplasm were observed under fluorescence spectroscopy. VVL did not exert ribosome-inactivating activity or induce changes in the expression of cyclins A, D1 and E. It did activate the expression of cyclin kinase inhibitors in a dose-dependent manner. VVL arrested cell proliferation by blocking cell cyle progression in the G2/M phase.

Rice straw was inoculated separately with both fungi, and samples of colonized substrate were studied. The presence of laccase and cellulase in P. sajor-caju enabled the fungus to efficiently utilize lignin, cellulose, and hemicellulose and to degrade lignin more actively until the end of the spawn run phase. During fructification, cellulose and hemicellulose degradation intensified. V. volvacea utilized cellulose and hemicellulose throughout the cropping phase, but was unable to utilize lignin at any stage due to the absence of laccase. P. sajor-caju, more efficient in substrate colonization due to a more active hydrolytic enzyme system, gave higher mycelium yield than V. volvacea.

The microbial succession in RPC was altered by environmental control and by adding a carbohydrate supplement (e.g. sucrose) at the start of composting, which encouraged a build-up of thermophilic bacteria. Actinomyces (fire fang) also appeared much earlier at the expense of undesirable mesophilic fungi.

AB:Five edible fungi (Panaeolus papilionaceus, Coprinus lagopus, Lentinus squarrosulus, Agaricus bisporus and Volvariella volvacea) on their optimum growing media (formulae given) were screened for extracellular inulinase and invertase activities. The enzymes were found to be produced constitutively by the fungi, but the carbon source (glucose, sucrose and starch) in the medium influenced the production of inpidual enzymes. The highest producers of inulinase and invertase were P. papilionaceus growing in starch medium and A. bisporus growing in glucose medium, respectively. A medium for the optimum production of invertase and inulinase (for commercial use) by P. papilionaceus was developed by determining the optimum concentrations of suitable carbon and nitrogen sources. Some of the physicochemical properties of the enzymes present in the culture filtrate were studied.

AB:The traditional method of Volvariella volvacea culture in humid tropical climates is outlined. For modern culture, a high cellulose substrate with a high C/N ratio is required. It is sterilized at 60C for 2-4 h after fermentation. After spawning, the temperature is maintained at 35-38?for about 4 days, then reduced to 30?to encourage flushing, and raised again after each flush. No casing is necessary. Picking is at the egg stage. All the flushes from a bed may be obtained in 15-20 days. Fresh yields vary from 12 to 30 kg/100 kg substrate dry matter. Data are tabulated on the composition of suitable substrates

AB:Protein carboxyl-methyl transferase was produced intracellularly by V. volvacea, when grown under shake-flask conditions for 7 days. Relatively high levels of enzymic activity were observed on the first day of growth, which decreased to almost half of the initial level from the second day onwards. Optimum conditions for the enzyme were 50C and pH 6. The Km for S-adenosyl-L-methionine was 2 M. S-Adenosyl-L-homocysteine appeared to be a competitive inhibitor, its Ki being 2.5 M. Enzymic and/or non-enzymic hydrolysis of methylated protein was observed even at pH 6. From these observations, the existence of a second class of protein carboxyl-methyl transferase (EC 2.1.1.77 [protein-L-isoaspartate (D-aspartate) O-methyltransferase]) was suggested.

Biomass yields obtained after 7 d growth on soyabean extract medium (SEM) adjusted to the appropriate opt. growth pH were (mg dry wt./ml) :C. versicolor, 1.5; L. shimeji, 2.7; M. elata, 2.7; P. sajor-caju, 3.8; T. lobayense, 1.5; and V. volvacea, 3.9. Highest enzyme levels on soyabean waste medium (SWM) were recorded in cultures of L. shimeji and P. sajor-caju with max. activities observed after 4 and 6 d, resp. P. sajor-caju grown on SEM produced higher titres of amylase with peak levels 3-fold greater than with SWM cultures. SEM was not a good medium for the expression of xylanase but SWM produced relatively high levels in submerged cultures of C. versicolor, V. volvacea and P. sajor-caju. Low but detectable levels of cellulase (CMCase) were observed when each of the fungi were grown on SWM. No CMCase activity was detected in SEM cultures. Highest titres for protease production on SEM were detected in cultures of V. volvacea and T. lobayense. Higher protease production was observed on SWM with max. enzyme levels 800 and 40% higher for T. lobayense and V. volvacea, resp. Soyabean waste was a good substrate for biomass production, and the expression of amylolytic, xylanolytic and proteolytic enzymes, by selected mushroom fungi. Considerable potential exists for converting soyabean wastes into added-value products using systems based on these fungi.
