sp. nov., a moderately halophilic bacterium from solar saltern soil Free

Abstract

A Gram-staining-positive, moderately halophilic bacterium, designated strain BH097, was isolated from solar saltern soil of Bigeum Island in south-west Korea. Cells were motile rods, producing spherical endospores at a terminal position in swollen sporangia. Strain BH097 was strictly aerobic, grew at pH 5.5–9.5 (optimum, pH 8.0), at 10–52 °C (optimum, 37 °C) and at salinities of 1–22 % (w/v) NaCl (optimum, 7 % NaCl). On the basis of 16S rRNA gene sequence analysis, strain BH097 was shown to belong to the genus within the phylum , and showed closest sequence similarity to DSM 19802 (95.8 %), TP2-8 (95.6 %), DSM 17256 (95.5 %), ‘’ DSM 17858 (95.4 %) and DSM 17856 (95.2 %). The DNA G+C content of this novel isolate was 37.9 mol%. The major cellular fatty acids of strain BH097 were anteiso-C, iso-C and C, and its polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol two unknown phospholipids and a glycolipid. The isoprenoid quinone was MK-7, and the peptidoglycan type was A1γ, with -diaminopimelic acid as the diagnostic diamino acid. On the basis of polyphasic evidence from this study, strain BH097 represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is BH097 ( = KCTC 13130 = DSM 19028).
