Abstract:
A Gram-stain-positive, aerobic, nonmotile actinobacterium, designated strain YIM 93776T, was isolated from a saline sediment sample collected from Aiding Lake in Xinjiang Uygur Autonomous Region, Northwest China. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain YIM 93776T was affiliated to the genus Glycomyces and was closely related to Glycomyces albus TRM 49136T (97.6% sequence similarity), Glycomyces lacisalsi XHU 5089T (97.0%) and Glycomyces anabasis EGI 6500139T (96.2%). The cell wall contained meso-diaminopimelic acid and the whole-cell hydrolysates sugars were galactose, mannose, arabinase, glucose and ribose. The predominant menaquinones were MK-9 (H4) and MK-10 (H4). Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylglyceride, two unidentified phospholipids and two unidentified polar lipids were detected in the polar lipid extracts. Major fatty acids were anteiso-C17:0, iso-C15:0, iso-C16:0, anteiso-C15:0 and anteiso C17:1 A. The draft genome sequence of strain YIM 93776T was 5.37 Mbp in size with 69.5% DNA G + C content. The dDDH and ANI values between strain YIM 93776T and related neighbours were 25.0-34.3% and 77.3-79.8%, respectively. On the basis of morphological, chemotaxonomic and phylogenetic evidence, strain YIM 93776T; therefore, represents a novel species, for which the name Glycomyces salinus sp. nov. is proposed. The type strain is YIM 93776T (= KCTC 49430T = CGMCC 4.7685T).
