双孢蘑菇(Agaricus bisporus)生长在以麦秆为基质的堆肥中,可以降解堆肥中相当一部分的干物质。已证实真菌菌丝能产生一组胞外降解酶,这些酶的组合活性可降解稿秆中木质素、纤维素、半纤维素和蛋白质等植物细胞壁的主要聚合物。某些酶大量产生,酶活性的改变与子实体产生有关。其中一种漆酶可能被菌丝作为补充氮源重新利用。除降 Agaricus bisporus, which grows on straw-based compost, can degrade a significant portion of the compost’s dry matter. It has been demonstrated that fungal hyphae produce a group of extracellular degrading enzymes whose combined activities can degrade the major polymers of plant cell walls such as lignin, cellulose, hemicellulose and proteins in manure. Some enzymes are produced in large quantities, and changes in enzyme activity are related to the production of fruiting bodies. One of the laccases may be reused by mycelium as a supplemental nitrogen source. In addition to drop
