摘    要:试验采用麦秸培养基,系统研究了姬松茸在生长期间对碳源的利用规律。结果表明,姬松茸降解的有机物质绝大部分被菌体的呼吸过程消耗掉,绝对生物学效率较低;在菌丝生长阶段,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;非木质纤维素组分在菌丝生长阶段被主要利用,而木质纤维素则是子实体生长阶段的主要碳源。且就整个栽培过程而言,姬松茸生长发育所需要的79.86%的碳源来自木质纤维素。

关 键 词:姬松茸  纤维素  半纤维素  木质素

Abstract:This paper adopted wheat straw compost,studied the law of utilization of carbonsource ofAgaricus blazeiat the stage of whole growth and development.The results showed as follows: The organic matter was mostly consumed by respiration of the fungus,so the absolute biological efficiency was comparatively low;The degradation rate of lignin at mycelial growth stage 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,lignocel-lulose was the main carbon source for the fruiting stage of the fungus.In the whole process of cultivation,79.86% car-bon source for the growth and development of the fungus originated from lignocellulose.
Keywords:Agaricus blazei  Cellulose  Hemicellulose  Lignin
