Abstract

A Gram-reaction-negative, motile by gliding, rod-shaped bacterium, designated strain GH4-78, was isolated from the tidal mudflat of a beach in the Republic of Korea. Cells were aerobic, catalase-positive, oxidase-negative and produced cream-coloured colonies. Q-8 was the only isoprenoid quinone. The major fatty acids were summed feature 8 (C 7 and/or C 6), summed feature 3 (C ω6 and/or C ω7) and C. The major polar lipids are phosphatidylethanolamine and phosphatidylglycerol. Results of phylogenetic analyses based on 16S rRNA gene sequences revealed that strain GH4-78 formed a distinct lineage with (98.2 % sequence similarity). The DNA G+C content was 59.9 mol%. The average nucleotide identity value with the closest relative was 82.90 %. On the basis of the results from phenotypic, chemotaxonomic, phylogenetic and phylogenomic analyses, strain GH4-78 (=KCTC 62383=DSM 106349) represents a novel species of a new genus in the family , for which the name gen. nov., sp. nov. is proposed. Moreover, the transfers of Han . 2019 to comb. nov. and Shi . 2018 to gen. nov. as comb. nov. are also proposed, with the emended description of the genus .
