Abstract

A moderately halophilic bacterium, strain CG2.1, 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, Gram-negative rod that produced orange-pigmented colonies. Strain CG2.1 was able to grow at salinities of 3–25 % (w/v) and at temperatures of 15–40 °C. The pH range for growth was 5–9. Strain CG2.1 was a heterotroph capable of utilizing various carbohydrates as carbon sources. The organism reduced nitrate and showed phenylalanine deaminase activity. The major fatty acids were C 7, C and C cyclo 8. The DNA G+C content was 60.9 mol%. On the basis of the phenotypic and phylogenetic data, strain CG2.1 appeared to be a member of the genus and clustered closely with (97.1 % 16S rRNA gene sequence similarity). However, the level of DNA–DNA relatedness between the novel isolate and the most closely related species was low. On the basis of these data, strain CG2.1 represents a novel member of the genus , for which the name is proposed. The type strain is CG2.1 (=CECT 5902=LMG 23625).
