Sediminibacillus terrae sp. nov., a moderate halophile isolated from non-saline farm soil

A Gram-stain-positive, moderately halophilic, strictly aerobic, endospore-forming, rod-shaped bacterium, strain JSM 102062T, was isolated from a non-saline farm soil sample collected from Dehang Canyon in Hunan, PR China. Growth occurred with 0.5–20 % (w/v) NaCl (optimum 4–7 %) at pH 5.5–11.0 (optimum pH 8.0) and at 20–50 °C (optimum 30–35 °C). Contained cell-wall peptidoglycan based on meso-diaminopimelic acid and possessed menaquinone-7 (MK-7) as the major respiratory isoprenoid quinone. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, five unidentified phospholipids and an unidentified glycolipid. The DNA G+C content was 44.1 mol%. Phylogeny based on 16S rRNA gene sequences indicated that strain JSM 102062T belonged to the genus Sediminibacillus , sharing high 16S rRNA gene sequence similarities to Sediminibacillus halophilus EN8dT (99.4 %) and Sediminibacillus albus NHBX5T (98.3 %). The whole genomic analysis showed that strain JSM 102062T constituted a different taxon separated from the recognized Sediminibacillus species. Combined data from phenotypic and genotypic studies demonstrated that strain JSM 102062T represents a noval species of the genus Sediminibacillus , for which the name Sediminibacillus terrae sp. nov. is proposed; the type strain is JSM 102062T (=CCTCC AB 2014166T = CGMCC 1.12957T=DSM 28949T=KCTC 33541T).
