Jilinibacillus soli gen. nov., sp. nov., a novel member of the family Bacillaceae.

A Gram-positive, aerobic, rod-shaped, motile, endospore-forming bacterium, designated strain A12(T), was isolated from a saline and alkali soil samples in Baicheng City, western of Jilin Province, China. Growth occurred in 15-45 °C (optimum, 30 °C) and at pH 7.0-11.5 (optimum, pH 9.0) and in the presence of 0-10 % (w/v) NaCl [optimum, 1-3 % (w/v) NaCl]. Meso-DAP was present in the peptidoglycan. The predominant menaquinone was MK-7. The major polar lipid profile was phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidyl inositol-methyl and phosphotidylinositol dimannosid. The major fatty acid (>10 % of total fatty acids) was anteiso-C15:0. DNA G + C content was 36.2 mol %. The level of 16S rRNA gene sequence similarity between strain A12(T) and other recognized species of the family was below 95.6 %. Phylogenetic analysis based on 16S rRNA gene sequence data indicated that the strain A12(T) fell with the family Bacillaceae and formed a distinct taxon. Based on physiological, chemotaxonomic and phylogenetic analyses, strain A12(T) was considered to represent a novel species of a new genus, for which the name Jilinibacillus soli gen. nov., sp. nov. was proposed. The type strain of Jilinibacillus soli was A12(T) (=GIMN1.014(T) = CCTCC M2011164(T) = KCTC 33417(T)).
