Abstract

Cellulase activity and degradation of cellulose and lignin in wheat straw and formation of humus during degradation by Botryotrichum sp., Masoniella sp., Paecilomyces fusisporus, Sclerotium sp. and Trichurus spiralis was studied. All the cultures exhibited carboxy-methyl-cellulase activity, but cellulase activity on cellulose powder, filter paper and cotton was shown only by Masoniella sp., P. fusisporus and Sclerotium sp. when grown on cellulose powder in submerged culture conditions. However, when grown on wheat straw in solid culture all fungi exhibited FPD activity. All except Masoniella sp. degraded both cellulose and lignin efficiently as compared to cellulose. There was formation of humus like substances during growth of fungi on wheat straw.

摘要

研究了葡萄穗霉属、梅氏霉属、镰刀状拟青霉、核盘菌属和螺旋毛线虫在降解小麦秸秆过程中的纤维素酶活性、纤维素和木质素的降解以及腐殖质的形成。所有培养物均表现出羧甲基纤维素酶活性，但仅梅氏霉属、镰刀状拟青霉和核盘菌属在液体培养条件下生长于纤维素粉时，对纤维素粉、滤纸和棉花表现出纤维素酶活性。然而，当在固体培养条件下生长于小麦秸秆上时，所有真菌均表现出滤纸酶活性。与纤维素相比，除梅氏霉属外，所有真菌均能有效降解纤维素和木质素。真菌在小麦秸秆上生长期间形成了类腐殖质物质。
