The strain was identified using a polyphasic taxonomic approach. The strain grew well on Reasoner's 2A media and could grow in the presence of 0–4 % (w/v) NaCl (optimum, 1 %), at pH 9.0–11.0 and at 15–37 °C (optimum, 30 °C). Strain GW1-59T possessed ubiquinone-8 as the sole respiratory quinone. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids were summed feature 9 (10-methyl C16 : 0 and/or iso-C17 : 1  ω9c), iso-C15 : 0, iso-C16 : 0, iso-C17 : 0, C16 : 0 and iso-C11 : 0 3-OH. DNA–DNA relatedness with Lysobacter concretionis Ko07T, the nearest phylogenetic relative (98.5 % 16S rRNA gene sequence similarity) was 23.4 % (21.1–25.9 %). The average nucleotide identity value between strain GW1-59T and L. concretionis Ko07T was 80.1 %. The physiological and biochemical results and low level of DNA–DNA relatedness suggested the phenotypic and genotypic differentiation of strain GW1-59T from other Lysobacter species. On the basis of phenotypic, phylogenetic and genotypic data, a novel species, Lysobacter antarcticus sp. nov., is proposed. The type strain is GW1-59T (=CCTCC AB 2019390T=KCTC 72831T).", }
