Abstract

Two bacterial strains, KMM 3891 and KMM 3892, were isolated from internal tissues of the marine mollusc collected from the Sea of Japan. The novel isolates were Gram-negative, aerobic, faint pink–reddish-pigmented, rod-shaped, non-motile, stenohaline and psychrotolerant bacteria that were unable to degrade most tested complex polysaccharides. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Fatty acid analysis revealed C 6, C, C and C 7 as the dominant components. The major isoprenoid quinone was Q-7. The DNA G+C content of strain KMM 3891 was 51.7 mol%. According to phylogenetic analysis of 16S rRNA gene sequences, strains KMM 3891 and KMM 3892 were positioned within the as a separate branch, sharing <93 % sequence similarity to their phylogenetic relatives including , species, , and . Based on phenotypic characterization and phylogenetic distance, the novel marine isolates KMM 3891 and KMM 3892 represent a new genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain of is KMM 3891 (=NRIC 0753 =JCM 15738).
