gen. nov., sp. nov. isolated from Antarctic intertidal sediment, transfer of to gen. nov. as comb. nov.

A Gram-stain-negative, aerobic, non-flagellated and rod- or ovoid-shaped bacterium, designated as strain S4J41, was isolated from Antarctic intertidal sediment. The isolate grew at 0-37 °C and with 0.5-10 % (w/v) NaCl. It reduced nitrate to nitrite and hydrolysed Tween 80 and gelatin. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain S4J41 constituted a distinct phylogenetic line within the family and was closely related with some species in the genera , , , , and with 98.6-95.7 % 16S rRNA gene sequence similarities. The major cellular fatty acids were C, summed feature 8 (C ω7 and/or C ω6) and C and the major polar lipids were phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, phosphatidylethanolamine and one unidentified aminolipid. The sole respiratory quinone was Q-10. The genomic DNA G+C content of strain S4J41 was 60.3 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data obtained in this study, strain S4J41 is considered to represent a novel species in a new genus within the family , for which the name gen. nov., sp. nov. is proposed. The type strain is S4J41 (=MCCC 1K03508=KCTC 62793). Moreover, the transfer of Kim . 2019 to gen. nov. as comb. nov. (type strain 318-1=JCM 30927=KCTC 72105) is also proposed.
