abstract= A novel Gram-stain-positive, white-pigmented, non-motile, non-sporulating, catalase- and oxidase-positive, strictly aerobic coccus, designated strain ZXM223T, was isolated from a seawater sample collected from the coast of Qingdao, PR China, during a green algal bloom. It grew at pH 6.0–10.5 and 0–25.0 % (w/v) NaCl, with optimum growth at pH 8.5 and 3.0 % (w/v) NaCl. Growth occurred at 16–42 °C (optimum at 28 °C). The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Menaquinone 6 (MK-6) was the major respiratory quinone. The polar lipids were phosphatidylglycerol, three unidentified phospholipids and two unknown glycolipids. The peptidoglycan type was l-Lys–Gly5–6. The genomic DNA G+C content was 43.5 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain ZXM223T within the genus Salinicoccus, with sequence similarity of 92.2–97.1 % between ZXM223T and the type strains of this genus. The closest relatives were Salinicoccus kunmingensis YIM Y15T, ‘S. salitudinis’ YIM-C678 and S. alkaliphilus T8T. The DNA–DNA relatedness between strain ZXM223T and S. kunmingensis CGMCC 1.6302T and ‘S. salitudinis’ CGMCC 1.6299 ( = YIM-C678) was 37±3 and 30±2 %, respectively. The phenotypic, chemotaxonomic and phylogenetic characteristics and low DNA–DNA relatedness support the proposal of a novel species of the genus Salinicoccus, Salinicoccus qingdaonensis sp. nov., with the type strain ZXM223T ( = LMG 24855T  = CGMCC 1.8895T).,
