sp. nov., a swarming bacterium from Jeotgal, a traditional Korean fermented seafood, and emended description of the genus Free

Abstract

A novel -like, Gram-stain-negative, facultatively anaerobic, rod-shaped bacterium, designated strain JS9, was isolated from Korean fermented seafood, Jeotgal. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain JS9 belonged to the genus in the family The highest 16S rRNA gene sequence similarity of strain JS9 was to KCTC 2579 (98.98 %) and the genomic DNA G+C content is 39.0 mol%. DNA–DNA hybridization values were measured and strain JS9 showed <20.8 % genomic relatedness with closely-related members of the genus . The isolate showed bacterial motility and swarming activity similar to those of pathogenic but distinct from those of other species of the genus . The isolate grows optimally at 30 °C, at pH 7, and in the presence of 2 % (w/v) NaCl. The main respiratory quinones are ubiquinone Q-8 and Q-10, and the major cellular fatty acids are C, summed feature 3 and summed feature 8. The polar lipids comprise phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, an unidentified amino lipid, two unidentified amino-phospholipids, and three unidentified lipids. Based on phylogenetic, phenotypic, chemotaxonomic and genotypic analyses, strain JS9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JS9 (=KACC 18404=JCM 30699). An emended description of the genus is also provided.
