A moderately haloalkaliphilic, Gram-positive bacterium, designated as strain CM1T, was isolated from a crude sea-salt sample collected near Qingdao in eastern China. Strain CM1T was found to grow optimally at 37 °C and pH 9.0. It was shown to be aerobic, rod-shaped and capable of growth at salinities of 2.5–20 % (w/v) NaCl (optimum, 12 %). The genomic DNA G+C content was about 48 mol%. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0 and the major isoprenoid quinones were MK-7(H2) and MK-6(H2). Phylogenetic analyses based on 16S rRNA gene sequences revealed that CM1T is a member of the genus Bacillus and has less than 95.2 % gene sequence similarity to the most closely related strain, Bacillus salarius BH169T. Its DNA–DNA reassociation value with respect to B. salarius BH169T was 35.4 %. On the basis of phenotypic and molecular properties, strain CM1T represents a novel Bacillus species, for which the name Bacillus qingdaonensis sp. nov. is proposed. The type strain is CM1T (=CGMCC 1.6134T=JCM 14087T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain CM1T is DQ115802.

Phylogenetic trees based on maximum-parsimony and minimum-evolution analyses of the 16S rRNA gene sequences of strain CM1T and related species are available as supplementary figures in IJSEM Online.
