gen. nov., sp. nov., a halophilic actinobacterium isolated from saline soil of Xinjiang, Northwest of China.

A Gram-stain-positive, aerobic, moderate halophilic actinobacterium, designated strain YIM 96095, was isolated from a saline soil sample collected from Aiding Lake, Xinjiang, North-western China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate belonged to the family , formed a distinct subclade, and was most closely related to DSM 102030 and DSM 45697 with sequence identity values of 95.8 and 95.1%, respectively. Optimal growth occurred at 37 °C, pH 7.0-8.0 and with 5-16% (w/v) NaCl, with well-developed, non-fragmented substrate mycelia and single-, double-, or triple-wrinkled spore(s) on the mature aerial hyphae. The chemical analysis presented -diaminopimelic acid as the diagnostic diamino acid of the cell-wall peptidoglycan, and glucose, galactose and rhamnose as the major whole-cell sugars, and iso-C and anteiso-C as the major fatty acids. The phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, unidentified phospholipids and unidentified glycolipid. The menaquinones were MK-10(H), MK-10(H) and MK-9(H). Its G+C content was 69.7 mol% in the determined genome sequence. Based on phenotypic, chemotaxonomic and phylogenetic characteristics, a novel genus and species named gen. nov., sp. nov. is proposed for isolate YIM 96095 (=KCTC 49266=CGMCC 4.7636).
