Salinicoccus luteus sp. nov., isolated from a desert soil.
A moderately halophilic bacterium, strain YIM 70202(T), was isolated from a desert soil sample collected from Egypt and was subjected to a taxonomic investigation. In a phylogenetic dendrogram based on 16S rRNA gene sequence analysis, strain YIM 70202(T) was affiliated to the Salinicoccus clade, showing 94.5-96.8 % 16S rRNA gene sequence similarity to the recognized species of the genus Salinicoccus, in which Salinicoccus roseus CCM 3516(T) was the nearest neighbour. The DNA-DNA relatedness value of the novel isolate with S. roseus CCM 3516(T) was 12.7 %. The novel isolate grew at temperatures between 4 and 45 degrees C and at pH values ranging from 7.0 to 11.0, with an optimum of 30 degrees C and pH 8.0-9.0, respectively. Strain YIM 70202(T) grew optimally in the presence of 10 % NaCl (w/v) and growth was observed at NaCl concentrations in the range 1-25 % (w/v). Chemotaxonomic data revealed that strain YIM 70202(T) contained MK-6 as the predominant respiratory quinone, possessed L-Lys-Gly(5) as the cell-wall peptidoglycan, had phosphatidylglycerol, diphosphatidylglycerol and an unknown glycolipid as the polar lipids and contained i-C(15 : 0) and ai-C(15 : 0) as the predominant fatty acids. The DNA G+C content was 49.7 mol%. The biochemical and chemotaxonomic properties demonstrate that strain YIM 70202(T) represents a novel species of the genus Salinicoccus. The name Salinicoccus luteus sp. nov. is proposed with strain YIM 70202(T) (=CGMCC 1.6511(T)=KCTC 3941(T)) as the type strain.
