摘要
The medium components for the production of extracellular cellulases by Melanocarpus sp. MTCC 3922 were optimized using solid-state fermentation. Melanocarpus sp. cultured in optimized medium containing 1.5% urea, and 0.12% KH2PO4 along with a trace element solution and surfactant (Tween 20), produced endoglucanase (142.4 U/g of substrate), Avicel-adsorbable endoglucanase (27.0 U/g of substrate), Avicelase (0.65 U/ g of substrate), FPase (39.9 U/g of substrate) and β-glucosidase (109.0 U/g of substrate) activities. The presence of sulphate ions in traces stimulated endoglucanase yields. The IEF fractionation of the crude proteins from Melanocarpus sp. showed the expression of 3, 1 and 11 isoforms of endoglucanase, β-glucosidase and xylanase, respectively.
