sp. nov., a member of the isolated in Japan and Palau Free

Abstract

The taxonomic positions of two bacterial strains, MBIC01146 and MBIC01099, isolated from marine environments of Japan and Palau, respectively, were determined by using a polyphasic approach. The bacteria were aerobic, motile, Gram-negative rods and formed star-shaped aggregations. The G+C content of the genomic DNA ranged from 58.5 to 58.7 mol%. The major respiratory quinone was ubiquinone-10 and the predominant cellular fatty acids were C, C 6 and C 7. 16S rRNA gene sequence analyses based on both neighbour-joining and maximum-parsimony methods revealed that strains MBIC01146 and MBIC01099 were positioned within the cluster comprising and within subgroup -3 of the . The phenotypic and chemotaxonomic characteristics of the novel strains were similar to those of ; however, DNA–DNA hybridization tests showed that the isolates represented an independent species. The isolates could be differentiated from based on several characteristics. Therefore, strains MBIC01146 and MBIC01099 are considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is MBIC01146 (=NBRC 101030=CIP 109181). An emended description of Uchino 1999 is also given.
