Strain 200T grew optimally at pH 7.0 and in the absence of NaCl on R2A. Its optimum growth temperature was 20 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 200T belonged to the genus Sphingomonas . Strain 200T showed the highest sequence similarities to Sphingomonas kyeonggiense THG-DT81T (95.1 %) and Sphingomonas molluscorum KMM 3882T (95.1 %). Chemotaxonomic analysis showed that strain 200T had characteristics typical of members of the genus Sphingomonas . Ubiquinone 10 was the predominant respiratory quinone and sym-homospermidine was the polyamine. The major polar lipids were sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylcholine. The G+C content of the genomic DNA was determined to be 60.9 mol%. Strain 200T contained C16 : 0 (31.6 %), summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c, 22.7 %), summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c, 11.2 %), C18 : 0 (7.8 %) and C14 : 0 2OH (6.7 %) as the major cellular fatty acids. On the basis of phylogenetic analysis, and physiological and biochemical characterization, strain 200T should be classified as representing a novel species of the genus Sphingomonas , for which the name Sphingomonas antarctica sp. nov. is proposed. The type strain is 200T (=CCTCC AB 2016064T=KCTC 52488T).", }
