Salinihabitans flavidus gen. nov., sp. nov., isolated from a marine solar saltern.
A Gram-negative, non-motile and rod-shaped bacterial strain, ISL-46(T), belonging to the Alphaproteobacteria, was isolated from a marine solar saltern in Korea, and subjected to a polyphasic taxonomic study. Strain ISL-46(T) grew optimally at pH 7.0-8.0 and 30 degrees C and in the presence of 7 % (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C(19 : 0) cyclo omega8c, C(18 : 1)omega7c and 11-methyl C(18 : 1)omega7c as the major fatty acids. The DNA G+C content was 63.5 mol%. Strain ISL-46(T) 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-46(T) 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-46(T) 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-46(T) (=KCTC 22485(T)=CCUG 56758(T)).
