摘要
对黄孢原毛平革菌孢子悬浮液进行了紫外和微波诱变,并将筛选出的优势菌PU-69和PM-57与未经诱变的菌作对比实验.结果显示紫外诱变的PU-69,L ip酶活力提高了1.29倍,Mnp 1.27倍,Lac 1.31倍.微波诱变的PM-57,L ip酶活力提高了1.34倍,Mnp 1.33倍,Lac 1.3倍.微波诱变菌株的产酶能力略高于紫外诱变,其操作也更为简单.
The suspension of Phanerochaete chrysosporium was treated by UV and microwave irradiation,and the selected predominant strains which were named as PU -69 and PM -57, comparing with original ones. The results indicated that Lip enzyme activity of PU -69 increased 1.29 times,while Mnp 1.27 times, and Lac 1.31 times. Lip enzyme activity of PM- 57 increased 1.34 times,while Mnp 1.33 times,and Lac 1.3 times. Enzyme production of strain treated by microwave irradiation is higher than that treated by UV irradiation slightly, and it is also more convenience.
