【摘要】 从土壤中分离获得碱性纤维素酶产生菌嗜碱芽孢杆菌ＳＨＹ８－１，经紫外线（ＵＶ）、亚硝基胍（ＮＴＧ）、甲基磺酸乙酯（ＥＭＳ）诱变及反复的自然分离和压力选择，获得高产变异株ＳＨＹ８－５７２５，产酶量由０．８９８ｕ／ｍｌ提高到１５～２０ｕ／ｍｌ，对影响产酶的各因素进行了分析测试。更多还原

【Abstract】 Alkalophilic Bacillus SHY81 producing alkaline cellulase was isolated from soil. The strain was mutagenized by UV, NTG, EMS and was selected by pure culture and with pressure separation repeatedly. Then a hyperproductive mutant SHY85725 was obtained. The enzyme yield was increased from 0.898u/ml to 1520u/ml. The effects of various factors on enzyme production were examined.更多还原
