A Gram-stain-negative, heterotrophic, aerobic, non-motile, rod-shaped bacterial strain (GW1-59T) belonging to the genus Lysobacter was isolated from coastal sediment collected from the Chinese Great Wall Station, Antarctica. 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 0-4â% (w/v) NaCl (optimum, 1â%), 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 C16â:â0 and/or iso-C17â:â1 ω9c), iso-C15â:â0, iso-C16â:â0, iso-C17â:â0, C16â:â0 and iso-C11â:â0 3-OH. DNA-DNA relatedness with Lysobacter concretionis Ko07T, the nearest phylogenetic relative (98.5â% 16S rRNA gene sequence similarity) was 23.4â% (21.1-25.9â%). The average nucleotide identity value between strain GW1-59T and L. concretionis Ko07T was 80.1â%. 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).
