Abstract

A Gram-stain-negative, non-gliding, aerobic and rod-shaped bacterium, designated XJNY, was isolated from Sayram Lake (44° 30′ 30.41″ N 81° 12′ 39.55″ E), Xinjiang Province, north-west China, and was characterized taxonomically by a polyphasic study. Strain XJNY grew at salinities of 0–4 % (w/v) and temperatures of 4–37 °C. The pH range for growth was 6.5–8.5. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain XJNY belonged to the genus and was closely related to the type strain of with 97.8 % similarity. The DNA G+C content was 34.5 mol%. The major fatty acids were iso-C, iso-C G, anteiso-C, iso-C 3-OH, C 2-OH and iso-C 3-OH. The major respiratory isoprenoid quinone was menaquinone-6 (MK-6) and the polar lipids were phosphatidylethanolamine, an unidentified phospholipid, two unidentified aminolipids and four unidentified lipids. On the basis of morphological, physiological and molecular properties and phylogenetic distinctiveness, strain XJNY represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is XJNY (=KCTC 52638=MCCC 1H00183).
