Growth occurred at 4–28 °C (optimum 20 °C) and at pH 5.0–8.0 (optimum pH 7.0). Strain AQ6-291T contained iso-C15 : 1 G, iso-C15 : 0, C16 : 1ω5c, iso-C17 : 0 3-OH and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) as the major cellular fatty acids. The main polar lipids were phosphatidylethanolamine, unknown aminophospholipids, unknown phospholipids, five unknown aminolipids and two unknown polar lipids. MK-7 was the major respiratory quinone. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain AQ6-291T belonged to the genus Flavitalea . The DNA G+C content was 48.1 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain AQ6-291T is considered to represent a novel species of the genus Flavitalea , for which the name Flavitalea antarctica sp. nov. is proposed. The type strain is AQ6-291T (=CCTCC AB 2016109T=KCTC 52491T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001937
