Microbacterium sediminicola sp. nov. and Microbacterium marinilacus sp. nov., isolated from marine environments.
Two novel Microbacterium species are described on the basis of phenotypic, chemotaxonomic and genotypic studies. The two strains, designated YM10-847(T) and YM11-607(T), were isolated from river sediment and unidentified hydroid, respectively, of a marine lake. The strains were Gram-positive, catalase-positive bacteria with l-ornithine as the diagnostic diamino acid of the peptidoglycan. The acyl type of the peptidoglycan was N-glycolyl. The major menaquinones were MK-10 and MK-11 for YM10-847(T), and MK-11 and MK-12 for YM11-607(T). Mycolic acids were not detected. The DNA G+C content of strains YM10-847(T) and YM11-607(T) was 67.8 and 71.6 mol%, respectively. Comparative 16S rRNA gene sequence analysis revealed that the two strains belong to the genus Microbacterium. DNA-DNA relatedness data showed that YM10-847(T) and YM11-607(T) are two novel species of this genus. On the basis of these results, strains YM10-847(T) and YM11-607(T) represent two novel species of the genus Microbacterium, for which the names Microbacterium sediminicola sp. nov. and Microbacterium marinilacus sp. nov. are proposed. The type strains are YM10-847(T) (=MBIC08264(T)=DSM 18905(T)) and YM11-607(T) (=MBIC07778(T)=DSM 18904(T)), respectively.
