摘    要:本试验以牛粪、草地、树林和菜园土作为实验筛选菌源,分离纯化出能够降解纤维素"wl-x"及木聚糖(半纤维素)的菌株"wl-y",并分别对其进行形态学描述.利用实验室原有的白腐真菌黄孢原平毛革菌CICC40719与"wl-x"、"wl-y"进行多菌种小麦秸秆混合发酵,通过正交实验优化反应条件,结果表明:wl-x、wl-y、CICC40719菌株接种量为2%,1%,2%,蛋白胨0.15 g、MgSO4·7H2O 0.06 g时效果最佳.

关 键 词:小麦秸秆  降解菌  筛选  混合发酵

Abstract:In this experiment,cow dung,grassland soil,forest soil and garden soil were used as the sources of fungus.After domestication,separation and purification,1 cellulose-decomposing strain and 1 xylan-decom-posing strain,named wl-x and wl-y respectively,were obtained and introduced to investigate the colonial morphology and the enzyme activity.The wheat straw was co-fermented by wl-x,wl-y,Phanerochaete chryso-sprium CICC40719,and the optimal process conditions were improved by L16(4^5)orthogonal test.The results showed that the ideal formula of fermentation medium was 0.15 g peptone and 0.06 g MgSO4·7H2O when the inoculation amount of wl-x,wl-y and CICC40719 in 50 mL volume was 2%,1%and 2%,respectively.
Keywords:wheat straw  decomposing fungus  screening  mixed fermentation
