Sabulilitoribacter arenilitoris sp. nov., isolated from seashore sand.

Abstract

A Gram-stain-negative and non-motile bacterial strain that formed rods and orange-pigmented colonies, designated HMF6543T, was isolated from sand of seashore on the South Sea, Republic of Korea. Strain HMF6543T grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain HMF6543T belonged to the genus Sabulilitoribacter. The most closest related species was Sabulilitoribacter multivorans M-M16T (96.7 %, sequence similarity). Strain HMF6543T contained MK-6 as the predominant menaquinone and iso-C15 : 1 G, iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain HMF6543T were phosphatidylethanolamine, two unidentified aminolipids, one unidentified glycolipid and three unidentified lipids. The DNA G+C content of strain HMF6543T was 31.9 mol%. On the basis of the evidence presented in this study, strain HMF6543T represents a novel species of the genus Sabulilitoribacter, for which the name Sabulilitoribacterarenilitoris sp. nov. is proposed. The type strain is HMF6543T (=KCTC 52401T=NBRC 112674T).
