Abstract
- A Gram-staining-positive, aerobic, non-endospore-forming, coccus-shaped, non-flagellated, and non-motile bacterium, designated WN024T, was isolated from the natural saline–alkali wetland soil of Binhai new district, Tianjin, China. Cells of strain WN024T were catalase- and oxidase-positive. The isolate was able to grow between 20 and 45 °C (optimal at 33–37 °C), pH 6.5–11.0 (optimal 7.5–8.0), and in the presence of 5.0–25.0% NaCl (optimal at 10.0–15.0%, w/v). The isolate could be affiliated to the genus Salimicrobium and the highest 16S rRNA gene sequence similarity of strain WN024T to its closest relative Salimicrobium salexigens DSM 22782T was 97.9%. The size of the genome was 2,622,223 bp in size with a G + C content of 47.1%. The sole respiratory quinone of strain WN024T was MK-7, the predominant fatty acids were iso-C15:0, anteiso-C15:0 and anteiso-C17:0. The major polar lipids were phosphatidylglycerol (PG), glycolipid (GL), phospholipid (PL) and diphosphatidylglycerol (DPG). The cell-wall diamino acid was meso-diaminopimelic acid. The DNA–DNA hybridization values between strain WN024T and the closest relative S. salexigens DSM 22782T was 47.3 ± 2.3%. The highest average nucleotide identity (ANI) value was 92.3% to S. salexigens DSM 22782T (GenBank Accession No. GCA_900156705.1). Therefore, we propose a novel species in the genus Salimicrobium to accommodate this novel isolate, named Salimicrobium humidisoli sp. nov. The type strain is WN024T (= ACCC 19979T = KCTC 33897T).
