Abstract: A novel, Gram-stain-negative, aerobic, rod-shaped, non-motile and moderately halophilic bacterium, designated strain BJGMM-B45T, was isolated from a saline–alkali soil collected from Shandong Province, China. Growth of strain BJGMM-B45T occurred at 10–45 °C (optimum, 30 °C) and pH 5.0–12.0 (optimum, pH 7.0) on Luria–Bertani agar medium with 1–20 % (w/v) NaCl (optimum, 7–10 %). The predominant respiratory quinone was Q-9. The major cellular fatty acids (>5 %) were C18 : 1ω7c, C16 : 0, C19 : 0 cyclo ω8c, summed feature 3, C12 : 0 3-OH and C12 : 0. The genomic DNA G+C content was 57.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain BJGMM-B45T belonged to the genus
Halomonas
in the class
Gammaproteobacteria
. The closest relatives were
Halomonas cupida
DSM 4740T (98.2 % 16S rRNA gene sequence similarity) and
Halomonas denitrificans
M29T (97.8 %). Levels of DNA–DNA relatedness between strain BJGMM-B45T and
Halomonas cupida
CGMCC 1.2312T and
Halomonas denitrificans
DSM 18045T were 57.0 and 58.9 %, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic features, strain BJGMM-B45T 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-B45T ( = ACCC 05850T = KCTC 32409T).
