A Gram-positive, strictly aerobic and moderately halophilic bacterial strain HSD was obtained from the sea water sample collected from International Sea Water Bathing Place in Weihai, a city on the shore of the Yellow Sea. Strain HSD was bacillus. The optimum growth temperature was 32~37℃ and the optimum pH was 6.0~9.0. It could grow well at 100 g•L-1 salt mass concentration. The G+C mole fraction of its genomic DNA was 37.5%. 16S rRNA gene sequence indicated a close relationship to Alkalibacillus halophilus (DQ359731) with similarity of 99%. However, they had obvious difference in whole-cell main fatty acid components, cell size, cell morphology, motility, oxidase, gelatine liquefication, nitrate reduction, NaCl tolerance range, pH tolerance range, G+C mole fraction, sole carbon source, sole nitrogen source, antibiotic sensitivity and a source of the strain isolation. Comparing of these taxonomic characters of strain HSD with those of other type strains of the genus Alkalibacillus, the differences were more obvious. In view of multiple identification results, it was proposed that strain HSD was classified as the type strain of a new species of the genus Alkalibacillus under the name Alkalibacillus huanghaiensis sp.nov..
