Idiomarina halophila sp. nov., isolated from a solar saltern sediment
A Gram-stain-negative, halophilic bacterium, designated strain BH195T, was isolated from the sediment of the solar saltern pond located in Gomso, Republic of Korea. Strain BH195T 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 BH195T belongs to the genus Idiomarina , showing the highest sequence similarity to Idiomarina salinarum ISL-52T (97.4 %), Idiomarina homiensis PO-M2T (96.8 %), Idiomarina aestuarii KYW314T (96.7 %), and Idiomarina tainanensis PIN1T (96.7 %). The major cellular fatty acids of strain BH195T were iso-C11 : 0 3-OH, iso-C15 : 0 and iso-C11 : 0. 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 BH195T and I. salinarum KCTC 12971T was 33 %. On the basis of this polyphasic analysis, strain BH195T represents a novel species of the genus Idiomarina for which the name Idiomarina halophila sp. nov. is proposed. The type strain is BH195T ( = KACC 17610T = NCAIM B 02544T).
