Abstract

A Gram-stain-positive, halotolerant bacterium, designated strain BH128, was isolated from soil of a saltern located at Bigeum Island in south-west Korea. Cells were aerobic, motile, spore-forming rods and grew at 15–53 °C (optimum, 35 °C), at pH 5.5–9.0 (optimum, pH 7.0) and at salinities of 0–16 % (w/v) NaCl (optimum, 8 % NaCl). The predominant isoprenoid quinone was menaquinone-7 (MK-7), and the cell-wall peptidoglycan type was A1γ, with -diaminopimelic acid as the diagnostic diamino acid. The major fatty acids were iso-C, anteiso-C, iso-C and anteiso-C. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and four unknown phospholipids. The DNA G+C content was 36.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain BH128 belonged to the genus and showed highest similarity to CVS-14 (95.8 %). On the basis of the phylogenetic, phenotypic and chemotaxonomic analyses in this study, strain BH128 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is BH128 (=KACC 18690=NBRC 111874).
