Key Words purple nonsulfur photosynthetic bacteria, nonphotosynthetic bacteria, DNA-DNA hybridization
Abstract DNA-Dna hybridization by kinetic method was carried out between species of purple nonsulfur photosynthetic bacteria and nonphotosynthetic bacteria. The degree of homology percent were shown to be low (2~35 D%) with the exception of high homology %(72~88 D%) for strains within a species and between Rhodobacter capsulatus and Rhodopseudomonas blastica. The D% between the purple nonsulfur photosynthetic bacteria, Rhodopseudomonas palustris, and nonphotosynthetic bacteria, Pseudomona aeruginosa ATCC 27853 or Bradyrhizobium japonocum were a little higher (26~33 D%) than the D% between any other photosynthetic bacteria. The homology % between Rhodopseudomonas blastica and Rhodobacter capsulatus was 72 D%, which showed relationship.
