| Popis: | A Gram-negative, rod-shaped, non-motile, strictly aerobic bacterium, strain S3-63T, was isolated from desert sand of Xinjiang, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S3-63T had highest similarity to type strains of the genus Altererythrobacter, i.e. Altererythrobacter marinus H32T (97.2 % similarity), Altererythrobacter marensis MSW-14T (95.9 %), Altererythrobacter aestuarii KCTC 22735T (95.5 %), Altererythrobacter epoxidivorans JCS350T (95.1 %), Altererythrobacter namhicola KCTC 22736T (95.1 %), Altererythrobacter luteolus SW-109T (95.0 %) and Altererythrobacter indicus LMG 23789T (93.5 %). Growth occurred at 20–37 °C (optimum 30 °C), at pH 7.0–9.0 (optimum pH 8.0) and in 0–3 % (w/v) NaCl (optimum 1 %). The major respiratory quinone was ubiquinone-10 and the predominant cellular fatty acids were C18 : 1ω7c (50.8 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 12.6 %), C16 : 0 (12.3 %), C14 : 0 2-OH (7.3 %) and C17 : 1ω6c (4.5 %). The DNA G+C content was 64.6 mol%. Therefore, the phylogenetic, physiological and chemotaxonomic data demonstrated that strain S3-63T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter xinjiangensis sp. nov. is proposed; the type strain is S3-63T ( = CCTCC AB 207166T = CIP 110125T). An emended description of the genus Altererythrobacter is provided. |
