摘    要:栽培在棉籽壳培养基中的鸡腿菇具有较强的木质纤维素降解能力和较高的绝对生物学效率;木质纤维素是子实体生长阶段的主要碳源;CMC酶、FP酶和HC酶的活性变化与纤维素、半纤维素的降解速率正相关,漆酶的活性变化与木质素的降解速率正相关,而过氧化物酶的活性变化与木质素的降解速率没有相关性;淀粉酶在菌丝生长阶段活性较高,蛋白酶的活性高峰出现在子实体生长发育期。

关 键 词:鸡腿菇    木质纤维素降解    绝对生物学效率    胞外酶

Abstract:Coprinus comatus cultivated on cotton seed hull medium decomposed lignocellulose straggly and was high of absolute biological efficiency. Lignocellulose is the main carbon source for the fruiting stage of the fungus. There existed the positive correlation between the degradation rates of the cellulose and hemicellulose in the medium and the activities of extracellular CMCase (carboxymenthelcel lulase), FPase (filter paper cellulase) and HCase (hemicellu-lase), there also existed the positive correlation between the degradation rate of the lignin in the medium and the activity of extracellular laccase, but no correlation between the degradatio rate of the lignin in the medium and the activity of peroxidase. The activity of extracellular amylase was comparatively high at mycelial growth stage, and the protease activity peek was at teh time when the fruitbody matured.
Keywords:coprinus comatus  Absolute biological efficiency  Lignocellulose degradation  Extracellular enzyme
