A Gram-negative, non-motile and rod-shaped bacterial strain, ISL-46T, belonging to the Alphaproteobacteria, was isolated from a marine solar saltern in Korea, and subjected to a polyphasic taxonomic study. Strain ISL-46T grew optimally at pH 7.0–8.0 and 30 °C and in the presence of 7 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C19 : 0 cyclo
8c, C18 : 1
7c and 11-methyl C18 : 1
7c as the major fatty acids. The DNA G+C content was 63.5 mol%. Strain ISL-46T exhibited 16S rRNA gene sequence similarity values of 94.1–95.3 % to members of the phylogenetically related genera Roseivivax, Salipiger, Citreicella, Yangia and Citreimonas. Strain ISL-46T could be differentiated from the above-mentioned genera by differences in compositions of the major fatty acids and in some phenotypic properties. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain ISL-46T is considered to represent a novel genus and species, for which the name Salinihabitans flavidus gen. nov., sp. nov. is proposed. The type strain is ISL-46T (=KCTC 22485T=CCUG 56758T).
