title: Taxonomic study of the genus Brachybacterium: Brachybacterium nesterenkovii sp. nov.
abstract: A new species, Brachybacterium nesterenkovii, is proposed for a group of coryneform bacteria that were isolated from milk products. These organisms have morphological, biochemical, and chemotaxonomic characteristics that are peculiar to the genus Brachybacterium. In contrast to strains of the only previously described species of the genus, Brachybacterium faecium, the representatives of the new species lack glycine in their peptidoglycan, although the peptidoglycan is of the same general type, and have large amounts of rhamnose in their cells. The strains of B. nesterenkovii exhibit no serological relationship with strains of B. faecium; in a numerical phenotypic analysis the two species were easily separated and formed clear-cut clusters. DNA-DNA hybridization between the type strains of B. faecium and B. nesterenkovii showed a level of homology of 22%. Strain 35 (= IMV Ac-752) is the type strain of B. nesterenkovii.
