摘要
对担子菌LMPQ39菌丝原生质体进行了紫外光──LiCl复合处理后,得到突变株U39,再将其分别用60Co、HNO2两种方法处理,各获得突变株UCo39和UN39,它们的CMC酶活由原来LMPQ39的0.31u分别提高到0.46u和0.576u.酯酶同功酶电泳表明,UCo39、UN39和母株LMPQ39的酶谱出现了6条共同的谱带,同时也出现差异.突变株和母株的拮抗试验呈阳性。
In order to improve the CMCase activity of the Core Residue Cellulose-decomposing basidiomycetes LMPQ39, the author treated its protoplasts with a system of mutagenic agents such as UV-LiCL, 60Co and HNO2, resulting in two mutants UN39 and UCo39. Congo Red-Polysaccharide interaction was used in screening, and DNS assay system showed that the CMCase activity was improved from 0. 310u to 0. 576u and 0. 460u. Additionally,isoeasterase pattern and antagonism testified that the two mutants varied from the stool.
