Chromohalobacter salarius sp. nov., a moderately halophilic bacterium isolated from a solar saltern in Cabo de Gata, Almeria, southern Spain

Abstract

A moderately halophilic, Gram-negative bacterium (strain CG4.1(T)), which was isolated from a solar saltern at Cabo de Gata, a wildlife reserve located in the province of Almería, southern Spain, was subjected to a polyphasic taxonomic study. This organism was an aerobic, motile rod that produced colonies with a yellow pigment. Strain CG4.1(T) grew at salinities of 3-25 % (w/v), at 15-45 degrees C and at pH 5-9. The organism reduced nitrate, hydrolysed starch and had phenylalanine deaminase activity. The major fatty acids were C(18 : 1)omega7c, C(16 : 0) and C(19 : 0) cyclo omega8c. The DNA G+C content was 63.6 mol%. On the basis of phenotypic and phylogenetic data, strain CG4.1(T) appears to be a member of the genus Chromohalobacter and clustered closely with Chromohalobacter species, with 95-96 % similarity between their 16S rRNA gene sequences. However, DNA-DNA relatedness between the isolate and the type strains of Chromohalobacter species was low. Therefore, it is proposed that strain CG4.1(T) represents a novel species, Chromohalobacter salarius sp. nov. The type strain is strain CG4.1(T) (=CECT 5903(T)=LMG 23626(T)).
