Abstract
- A bacterial strain, designated TRPH29T, was isolated from saline-alkaline soil, collected from the southern edge of the Gurbantunggut desert, Xinjiang, People’s Republic of China. The isolate was Gram-staining positive, facultatively anaerobic, straight rods. Growth occurred at 15–40 °C (optimum, 28 °C), pH 8.0–13.0 (optimum, 10.0), and in the presence of 0–15% (w/v) NaCl (optimum, 2%). Phylogenetic analysis using 16S rRNA gene sequence indicated that strain TRPH29T showed the highest sequence similarities to Alkalihalobacillus krulwichiae (98.31%), Alkalihalobacillus wakoensis (98.04%), and Alkalihalobacillus akibai (97.69%). Average nucleotide identity (ANI) and digital DNA-DNA hybridization values between strain TRPH29T and Alkalihalobacillus krulwichiae, Alkalihalobacillus wakoensis, Alkalihalobacillus akibai were in the range of 73.62–75.52% and 15.0–21.20%, respectively. Results of genome analyses indicated that the genome size of strain TRPH29T was 5.05 Mb, with a genomic DNA G + C content of 37.30%. Analysis of the cellular component of strain TRPH29T revealed that the primary fatty acids were anteiso-C15:0 and iso-C15:0, and the polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified glycolipid, and an unidentified phospholipid. The predominant respiratory quinone was MK-7. Based on the genomic, phylogenetic, phenotypic and chemotaxonomic analyses, strain TRPH29T represents a novel species of the genus Alkalihalobacillus, for which the name Alkalihalobacillus deserti sp. nov. is proposed. The type strain is TRPH29T (= CGMCC 1.19067T = NBRC 115475T). [ABSTRACT FROM AUTHOR]
