本文对５个属１４个种共３３株捕食线虫真菌采用聚丙烯酰胺凝胶电泳技术进行了酯酶同工酶谱和可溶性蛋白质谱分析。结果表明，酯酶同工酶谱带少，但各属的特征谱带是明显的，在同属不同种之间，多数种都有自已的特征谱带与其它种相区别，同种不同菌株间没有明显差异；蛋白质谱带较多，在每个属中均有１～２条特征谱带，属间的谱带差异明显，同属不同种和同种不同菌株间蛋白质谱带都表现出多型性
In this paper, esterase isoenzymes and soluble protein profiles of 33 predacious nematode fungi from 14 species were analyzed by polyacrylamide gel electrophoresis. The results showed that the esterase isozyme band with less, but the genera of the characteristic bands are obvious, between the same species, most species have their own characteristic bands and other species are different, the same strains of different strains There was no significant difference between the two genotypes. There were more protein bands, with 1 ~ 2 characteristic bands in each genus, and significant differences among the genus bands. The protein bands of different genus and different strains showed polymorphism Sex
