Abstract

A novel Gram-stain-positive, endospore-forming bacterium, designated strain FJAT-18043, was isolated from a soil sample of a potato field in Xinjiang Autonomous Region, China. Cells were rods that were catalase-positive and motile by peritrichous flagella. The strain grew at 20–45 °C (optimum 35 °C), at pH 6.0–10.0 (optimum pH 9) and with 0–10 % (w/v) NaCl (optimum 0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FJAT-18043 belonged to the genus and exhibited similarities of 97.7, 97.6, 97.2 and 97.2 % with A1-2, DSM 23495, WCC 4585 and DS22, respectively. DNA–DNA relatedness between strain FJAT-18043 and A1-2 was lower than 70 % (36.1 %). The menaquinone was identified as MK-7 and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids detected were anteiso-C, iso-C, iso-C, anteiso-C, C and iso-C. The DNA G+C content was 48.8 mol%. Phenotypic, chemotaxonomic and genotypic properties clearly indicated that isolate FJAT-18043 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is FJAT-18043 ( = DSM 29501 = CCTCC AB 2014277).
