The bacterium grew optimally at 28 °C, pH 7.0 and in the presence of 0–4.0 % (w/v) NaCl. On the basis of the results of 16S rRNA gene sequence phylogenetic analyses, it was concluded that 16-35-5T represented a member of the genus Acidovorax and had the highest sequence similarities with Acidovorax anthurii CFBP 3232T (96.48 %). The genome of 16-35-5T is 4.2 Mb long with a DNA G+C content of 66.3 mol%. Average nucleotide identity (ANI) value between the genomes of 16-35-5T and Acidovorax wautersii DSM 27981T, was 85.29 %. Strain 16-35-5T had ubiquinone-8 (Q-8) as the respiratory ubiquinone. The polar lipids of 16-35-5T were consisted of phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The main fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 25.2 %), summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c, 12.9 %), C16 : 0 (35.2 %), and C17 : 0 cyclo (19.0 %). On the basis of the evidence presented in this study, 16-35-5T should be classified as representing a novel species of the genus Acidovorax , for which the name Acidovorax antarcticus sp. nov., is proposed, with the type strain 16-35-5T (=CCTCC AB 2019325T=KCTC 72915T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004744
