Abstract

A Gram-positive bacterium, strain M-6-3, was isolated from salt-fermented seafood in Korea. The organism grew in 0–10 % (w/v) NaCl and at 25–37 °C, with optimal growth occurring in 5 % NaCl and at 28–30 °C. The peptidoglycan type was variation A4γ with -diaminopimelic acid as the diagnostic cell-wall diamino acid. The polar lipid profile of strain M-6-3 consisted of diphosphatidylglycerol, phosphatidylglycerol, an unidentified phospholipid and an unknown glycolipid. Strain M-6-3 contained MK-7 as the major component of the quinone system and anteiso-C (62.1 %) as the predominant fatty acid. Based on 16S rRNA gene sequence similarity studies, strain M-6-3 was most closely related to LMG 19848 (98.5 %). The G+C content of the genomic DNA was 71.5 mol% and the mean DNA–DNA hybridization value with reference strains was 14.32±2.0 %. Based on phenotypic, genotypic and phylogenetic analyses, it is proposed that strain M-6-3 represents a novel species for which the name sp. nov. is proposed; the type strain is M-6-3 ( = KACC 14221  = JCM 16464).
