Abstract

A novel Gram-staining-negative, facultatively anaerobic, motile and rod-shaped bacterium, designated strain LHW37, was isolated from a dead ark clam collected on the south coast of Korea. The novel strain grew optimally at 37 °C, at pH 7.0–8.0 and with 2 % (w/v) NaCl. The predominant cellular fatty acids were Cω7 and summed feature 3 (Cω7 and/or iso-C 2-OH). The major isoprenoid quinone was ubiquinone-8 (Q-8) and the predominant polar lipids were phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel strain was most closely related to JAMM 0745 (97.1 % sequence similarity). The genomic DNA G+C content of strain LHW37 was 48.2 mol%. The DNA–DNA relatedness values recorded in hybridization experiments between the novel strain and its closest known relative were ≤18 %. Based on the phenotypic, genotypic and phylogenetic data, strain LHW37 represents a novel species belonging to the genus for which the name sp. nov. is proposed. The type strain is LHW37 ( = KACC 15543  = JCM 17730). An emended description of the genus is also provided.
