紫外、微波诱变黄孢原毛平革菌菌株的筛选比较

Screening strain of Phanerochaete chrysosporium mutagenized by UV and microwave irradiation

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,Lip酶活力提高了1.29倍,Mnp1.27倍,Lac1.31倍.微波诱变的PM-57,Lip酶活力提高了1.34倍,Mnp1.33倍,Lac1.3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.

Abstract: The suspension of Phanerochaete chrysosporium was treated by UVand 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 UVirradiation slightly,and it is also more convenience.
