Abstract

A moderately halophilic, Gram-negative bacterium (strain CG4.1), 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 grew at salinities of 3–25 % (w/v), at 15–45 °C and at pH 5–9. The organism reduced nitrate, hydrolysed starch and had phenylalanine deaminase activity. The major fatty acids were C 7, C and C cyclo 8. The DNA G+C content was 63.6 mol%. On the basis of phenotypic and phylogenetic data, strain CG4.1 appears to be a member of the genus and clustered closely with species, with 95–96 % similarity between their 16S rRNA gene sequences. However, DNA–DNA relatedness between the isolate and the type strains of species was low. Therefore, it is proposed that strain CG4.1 represents a novel species, sp. nov. The type strain is strain CG4.1 (=CECT 5903=LMG 23626).
