摘要
巴西蘑菇能够降解棉籽壳和麦草两种培养基中木质纤维素复合体中的全部组分,属于白腐真菌;巴西蘑菇降解的有机物质的绝大部分被菌体的呼吸过程消耗掉,其绝对生物学效率较低,仅为4.41%～5.25%;在栽培前期木质素的降解速率大于纤维素和半纤维素,这对纤维素和半纤维素的降解十分有利;非木质纤维素组分主要在菌丝生长阶段被利用,而木质纤维素是子实体生长发育阶段的主要碳源;就整个栽培过程而言,巴西蘑菇生长发育所需要的82.39%～84.50%的碳源来自木质纤维素.
Agaricus blazei is able to degrade all members of lignocellulose complex in cotton seed hull and wheat straw composts, so it belongs to white-rotting fungus. The organic matter was mostly consumed by respiration of the fungus, so the absolute biological efficiency (biomass of fruitbodies) was comparatively low, only up to 4.41%~5.25%. The degradation rate of lignin at the early period of cultivation was higher than that of cellulose and hemicellulose, facilitating the degradation of cellulose and hemicellulose of the fungus. Nonlignocellulose was mainly utilized at the stage of mycelial growth, however, lignocellulose was the main carbon source for the fruiting stage of the fungus. In the whole process of cultivation, 82.39%~84.50% carbon source for the growth and development of the fungus originated from lignocellulose.
