【摘要】 <正> 全细胞可溶性蛋白的凝胶电泳分析作为细菌分类的一种简便而客观的方法得到了广泛应用,在许多报道中已证明蛋白凝胶电泳分析和DNA-DNA杂交的结果有紧密的相关性.目前在许多属中进行了全细胞蛋白组分的数值分类研究,我们对52株链霉菌进行了SDS-PAGE分析,并以全细胞蛋白组分进行聚类分析,以期在全细胞蛋白组分上探讨链霉菌属内种间及种内不同菌株的亲缘关系.更多还原

【Abstract】 By using SDS-PAGE, fifty two strains Streptomyces were analysed for whole-cell protein composition. Electrophore pattern was divided into fifty composition for numerical taxonomy. The clustering result indicate that all strains’s similarity is over 72 percent and different strains in a species is over 84 percent. The most similar strains is 96 percent.更多还原
