Abstract

A Gram-stain-negative, halophilic bacterium, designated strain BH195, was isolated from the sediment of the solar saltern pond located in Gomso, Republic of Korea. Strain BH195 was a strictly aerobic, non-motile rod, which grew at pH 3.5–10.5 (optimum, pH 7.5), at 4–55 °C (optimum, 30 °C) and at salinities of 0.5–11 % (w/v) NaCl [optimum, 2–3 % (w/v) NaCl]. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain BH195 belongs to the genus , showing the highest sequence similarity to ISL-52 (97.4 %), PO-M2 (96.8 %), KYW314 (96.7 %), and PIN1 (96.7 %). The major cellular fatty acids of strain BH195 were iso-C 3-OH, iso-C and iso-C. The DNA G+C content was 51.3 mol% and the major respiratory quinone was ubiquinone 8. The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and an unknown phospholipid. DNA–DNA relatedness between strain BH195 and KCTC 12971 was 33 %. On the basis of this polyphasic analysis, strain BH195 represents a novel species of the genus for which the name Idiomarina sp. nov. is proposed. The type strain is BH195 ( = KACC 17610 = NCAIM B 02544).
