Abstract

A Gram-positive bacterial strain containing -ornithine as the diagnostic diamino acid was isolated from a sea-water-sample from the East Sea, Korea. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain JC1078 represents a phyletic line within the suborder of the order , adjacent to the genus . The highest sequence similarity values to the isolate were observed against (94·3 %) and (94·1 %). The strain was strictly aerobic and moderately halophilic with optimal growth at 2–3 % (w/v) NaCl. Cells were non-motile, non-sporulating and coccoid-shaped. The cell wall contains -ornithine, glutamic acid, alanine, glycine and serine. The major menaquinone was MK-8(H). The predominant cellular fatty acids were of the iso- and anteiso-methyl-branched types. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unknown glycolipid. The acyl type of the glycan chain of peptidoglycan is acetyl. The DNA G+C content was 72 mol%. The combination of physiological, biochemical and chemotaxonomical data clearly separated the marine isolate from other members of the suborder . On the basis of polyphasic evidence, it is proposed to classify strain JC1078 in a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain is JC1078 (=IMSNU 14026=KCTC 9980=DSM 15273).
