ABSTRACT
A novel, Gram-stain-negative, aerobic, rod-shaped, non-motile and moderately halophilic bacterium, designated strain BJGMM-B45(T), was isolated from a saline-alkali soil collected from Shandong Province, China. Growth of strain BJGMM-B45(T) occurred at 10-45 °C (optimum, 30 °C) and pH 5.0-12.0 (optimum, pH 7.0) on Luria-Bertani agar medium with 1-20â% (w/v) NaCl (optimum, 7-10â%). The predominant respiratory quinone was Q-9. The major cellular fatty acids (>5â%) were C18ââ1ω7c, C16ââ0, C19ââ0 cyclo ω8c, summed feature 3, C12ââ0 3-OH and C12ââ0. The genomic DNA G+C content was 57.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain BJGMM-B45(T) belonged to the genus Halomonas in the class Gammaproteobacteria. The closest relatives were Halomonas cupida DSM 4740(T) (98.2â% 16S rRNA gene sequence similarity) and Halomonas denitrificans M29(T) (97.8â%). Levels of DNA-DNA relatedness between strain BJGMM-B45(T) and Halomonas cupida CGMCC 1.2312(T) and Halomonas denitrificans DSM 18045(T) were 57.0 and 58.9â%, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic features, strain BJGMM-B45(T) is considered to represent a novel species of the genus Halomonas, for which the name Halomonas huangheensis sp. nov. is proposed. The type strain is BJGMM-B45(T) (â=âACCC 05850(T)â=âKCTC 32409(T)).
