【摘要】 <正> 细菌分类,向以形态学和生理生化特征为主要依据。近年来,由于分子生物学的进展,提供了很多新技术,使细菌分类的研究进入分子水平。此类研究结果反映了细菌之间的亲缘关系,因而更确切地反映了细菌各属、种之间的进化联系。凝胶双向扩散试验属于免疫学方更多还原

【Abstract】 Antigenic determinant divergence of superoxide dismutases (SODs) from 16 strains of marine luminous bacteria was determined by Ouchterlony double diffusion procedure. Re-sults:16 strains of bacteria were divided into two groups,the genus Vibrio and the Photoba-cterium.These were in agreement with our former classification based on phenotype, in which V. fischeri and V.logei were assigned to genus Vibrio.更多还原
