摘要
从腐烂朽木及附近土壤筛选分离到一株高纤维素酶活性的纤维素分解菌CDY-3,经初步鉴定其为芽孢杆菌属菌株。pH 5时,该菌羧甲基纤维素酶活性最高达14.59 IU,对滤纸有较强的降解能力。生理生化特性表明该菌最适生长条件为30℃,pH 7。
CDY-3 was isolated from decayed wood and soil around it, It was identified as Bacillus sp. preliminary. The CMCase activity of CDY-3 is 14.59 IU at pH 5 and the strain also has better decomposing ability for filter paper. The physiological and bio-chemistry characteristics of strain CDY-3 showed the optimal pH is 7 and the optimal temperature is 30℃.
