{Abstract}: The present study was conducted with the aim of finding out the most favourable month for the cultivation of Calocybe indica and records the influence of temperature and relative humidity on mushroom yield. Significant variation in the yield and other parameters existed when C. indica was grown during different months of 2004 to 2005. In summer months (March to July), a general increase in mushroom yield was observed. The maximum yield was recorded in the month of July 2005 (450.6 g per bed). However, the yields obtained in the months of April, May and June 2005 was found to be on par with that of the above observation. Mushroom attained harvesting maturity almost one day earlier during monsoon months. In addition, during this period, the average weight of individual mushroom was found to be comparatively high. Interestingly, a marginal but comparable reduction in stipe length was noticed during summer months

{Abstract}: As agricultural wastes are easily accessible and quite free sources, re-use of them could be considered as a break through in production management, especially if it sustains the production efficiency as standard materials do. In this study, we evaluated combination usage of substrates including wood chips, boll, Sugar Beet Pellet Pulp (SBPP) and palm fiber along with wheat bran, rice bran, soya cake powder, Soya Cake Powder + Rice Bran (SCPRB) and carrot pulp as supplements. Substrates with no supplement were regarded as control groups. Results revealed that boll, SBPP and palm fiber, which could be abundantly in Iran, had better growth period, fruiting body weight, yield and biological efficiency than wood chips. Moreover, SCRBP had the highest yield, biological efficiency and fruiting body weight among all substrates. We also assessed combination effects of substrates and complements. The least growth period (30.3 d) belonged to sugar beet pulp enriched with soya cake powder. The lowest fruiting body weight (12.4 g) was produced in boll substrate with no supplement, though maximum fruiting body number (34.3) belonged to this group. The highest fruiting body weight (41.5 g) was achieved when the enriched palm fiber by rice bran supplement was used. In addition, the highest yield and biological efficiency was found on boll substrate enriched with a mixture of soya cake powder and rice bran supplements (794.3 and 158.9 g, respectively).

{Abstract}: Spent white-rot fungi (Pleurotus ostreatus) substrate has been used to biotreat Nigerian oil-based drill cuttings containing polycyclic aromatic hydrocarbons (PAHs) under laboratory conditions. The Latin square (LS) experimental design was adopted in which four options of different treatment levels were tested in 10 L plastic reactors containing fixed masses of the drill cuttings and fresh top-soil inoculated with varying masses of the spent P. ostreatus substrate. Each option was replicated three times and watered every 3 days under ambient conditions for a period of 56 days. Microcosm analysis with a series II model 5890 AGILENT Hp (R) GC-FID showed that, the PAHs in the drill cuttings were mainly composed of 2 to 5 fused rings with molecular-mass ranging from 128 to 278 g/mol, while the total initial PAHs concentration of the drill cuttings was 806.31 mg/kg. After 56 days of composting, the total amount of residual PAHs in the drill cuttings decreased to between 19.75 and 7.62%, while the overall degradation of PAHs increased to between 80.25 and 92.38% with increasing substrate addition. Individual PAH degradation ranged from 97.98% in acenaphthene to 100% in fluorene, phenanthrene and anthracene. Statistical analysis, using the 2-factor analysis of variance (ANOVA), showed that there were no significant differences (p < 0.05) in the biodegradation of the PAHs due to the substrate levels applied and remediation period, as well as a nonsignificant (p < 0.05) interaction between substrate levels applied and remediation period. These results showed that spent white-rot fungi (P. ostreatus) substrate may be suitable for biotreating PAH-contaminated Nigerian oil-based drill cuttings.

{Abstract}: A total of eight dyes from the triphenylmethane, azo and polymeric/heterocyclic dye group were decolourized by enzyme cocktail extracted from five month old spent compost of Pleurotus sajor-caju with lignin peroxidase as the main enzyme. The percentage of decolourisation for tryphan blue, amido black, remazol brilliant blue R (RBBR) and bromophenol blue ranged between 80 - 90% after 4 h reaction. However, the percentage of decolourisation for crystal violet, methyl green and congo red was lower than the other dyes from the same dye group with only 60 - 65% after 12 h. Methylene blue exhibited the least decolourisation with only 43% after 24 h indicating that this dye is a poor substrate for the enzyme. The rate of decolourisation for crystal violet, tryphan blue, amido black, congo red and RBBR dyes by enzymes from spent mushroom compost (SMC) were also calculated. The rate of decolourisation for all the dyes was positively affected by the initial dye concentration, pH between 4.0 - 4.5 and temperature range of 30 - 35 C. The optimum concentration of veratryl alcohol as redox mediator was between 0 - 2 mM for all the dyes except for RBBR. The optimum veratryl alcohol concentration for RBBR was 4 mM. Based on the effect of hydrogen peroxide on the rate of decolourisation of each dye, the dyes could be divided into two groups. From the results of the present study, it could be concluded that the enzymes extracted from the spent compost of P. sajor-caju offers an economical advantage of obtaining industrially important enzymes, which have potential in the bioremediation of synthetic dyes. Furthermore, the utilization of spent compost for the extraction of enzymes can also offer a possible solution for the problem posed due to the disposal of large amounts of spent mushroom compost.
