[Differentiation of the genera of coryneform bacteria synthesizing amino acids and nucleotides].

The morphological, cultural, physio-biochemical and chemotaxonomic properties as well as the content of GC in DNA were studied in coryneform bacterial strains producing amino acids and nucleotides. It has been shown that Brevibacterium ammoniagenes VKM 672, B. flavum 317A, B. stationis CCM 317 and Corynebacterium VSTI 301 should be assigned to the genus Corynebacterium. The taxonomic significance of chemotaxonomic and physio-biochemical properties is discussed on the basis of the results obtained and the data reported in literature. Apparently, coryneform bacterial genera having such chemotaxonomic properties as meso-DAPA, arabinose galactose and mycolic acids are related, and their physio-biochemical characteristics reflect the evolutionary development of coryneform bacterial groups in the course of which they have adapted to various ecological niches.
