Abstract:
A Gram-stain-negative, aerobic, non-flagellated and rod- or ovoid-shaped bacterium, designated as strain S4J41 T , 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 T constituted a distinct phylogenetic line within the family Rhodobacteraceae and was closely related with some species in the genera Ruegeria , Phaeobacter , Pseudopuniceibacterium , Sulfitobacter , Puniceibacterium and Poseidonocella with 98.6–95.7 % 16S rRNA gene sequence similarities. The major cellular fatty acids were C 16 : 0 , summed feature 8 (C 18 : 1 ω7 c and/or C 18 : 1 ω6 c ) and C 18 : 0 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 T was 60.3 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data obtained in this study, strain S4J41 T is considered to represent a novel species in a new genus within the family Rhodobacteraceae , for which the name Antarcticimicrobium sediminis gen. nov., sp. nov. is proposed. The type strain is S4J41 T (=MCCC 1K03508 T =KCTC 62793 T ). Moreover, the transfer of Ruegeria lutea Kim et al . 2019 to Antarcticimicrobium gen. nov. as Antarcticimicrobium luteum comb. nov. (type strain 318-1 T =JCM 30927 T =KCTC 72105 T ) is also proposed.
