摘要: 从腐烂的秸秆、树叶、玉米地土壤及内蒙古农业大学动物科学与医学学院畜粪中分离到4株降解纤维素能力强的菌株,培养7d时直径分别达到3920.8,808.8,541.8和5110.56Ixm;在pH值分别为6.0和6.5时降解率最高;酶活最高分别可迭203,301,262和276U。

Abstract: Four strains contained strong degrading ability cellulose-decomposing bacteria were isolated from rotten straw, leaves, soil in corn field, and animal dung from college of animal science and medicine of Inner Mongolia Agricultural University. The diameters of the four strains were up to 3920.8, 808.8, 541.8 and 5110.56 μm respectively after seven days' cultivation. The degradation rate reaches peak value when pH is 6.0 or 6.5, and the highest enzymatic activity can be up to 203, 301,262 and 276 U respectively.
