Abstract

A Gram-stain-negative, halophilic bacterium, designated strain BH195(T), was isolated from the sediment of the solar saltern pond located in Gomso, Republic of Korea. Strain BH195(T) 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(T) belongs to the genus Idiomarina , showing the highest sequence similarity to Idiomarina salinarum ISL-52(T) (97.4%), Idiomarina homiensis PO-M2(T) (96.8%), Idiomarina aestuarii KYW314(T) (96.7%), and Idiomarina tainanensis PIN1(T) (96.7%). The major cellular fatty acids of strain BH195(T) were iso-C(11&#8202:&#82020) 3-OH, iso-C(15&#8202:&#82020) and iso-C(11&#8202:&#82020). 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(T) and I. salinarum KCTC 12971(T) was 33%. On the basis of this polyphasic analysis, strain BH195(T) represents a novel species of the genus Idiomarina for which the name Idiomarina halophila sp. nov. is proposed. The type strain is BH195(T) (&#8202=&#8202KACC 17610(T)&#8202=&#8202NCAIM B 02544(T)).
