gen. nov., sp. nov., a moderately halophilic bacterium isolated from sea sand Free

Abstract

A Gram-stain-negative, non-pigmented, non-spore-forming, non-motile, strictly aerobic bacterial strain, designated CAU 1038, was isolated from a sea sand sample in Modo, Republic of Korea, and its taxonomic position was examined using a polyphasic approach. Cells of strain CAU 1038 grew optimally at 30 °C, pH 7.5 in 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1038 formed a distinct lineage within the class as a separate deep branch, with 95.2 % or lower sequence similarity to representatives of the genera , and , and 92.3 % or lower with , and . The major cellular fatty acids of strain CAU 1038 were C, Cω7 and Cω7c. The polar lipid pattern of the isolate consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid and two unidentified lipids. The strain contained lipoquinone (Q-8) as the sole respiratory quinone. The G+C content of the genomic DNA was 65 mol%. On the basis of phenotypic and chemotaxonomic data, and phylogenetic inference, strain CAU 1038 represents a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. The type strain of the type species is CAU 1038 ( = KCTC 42300 = NBRC 110727).
