Abstract

A lemon-shaped marine bacterium, strain CL-SP20, isolated from hypersaline water from a solar saltern in Korea, was characterized in terms of its physiological and biochemical features, its fatty acid profile and its phylogenetic position based on 16S rRNA gene sequences. Analysis of the 16S rRNA gene sequence revealed a clear affiliation with the lineage (91.0–96.3 % similarity) of the family . However, strain CL-SP20 did not form a robust clade with any species of the clade, forming a distinct subline. Strain CL-SP20 is non-motile and forms beige colonies on marine agar. The strain is able to grow with sea salts at concentrations in the range 1–10 %, with optimal growth between 5 and 6 %. It grows at temperatures in the range 15–40 °C and at pH 6–10. The strain cannot oxidize thiosulfate. The fatty acids are dominated by 18 : 17 (54.3 %) and 19 : 0 cyclo 8 (20.4 %). The DNA G+C content is 67.3 mol%. According to the physiological data, fatty acid composition and phylogenetic analysis of the 16S rRNA gene sequence, strain CL-SP20 represents a novel species in a novel genus of the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is CL-SP20 (=KCCM 42116=JCM 13036).
