- Abstract
- A Gram-negative, non-motile, short rod-shaped aerobic bacterial strain CAU 1593(T) was isolated from a coastal sand sample collected in the Republic of Korea. Cells of strain CAU 1593(T) grew optimally at 30 degrees C and pH 7.5 in 4% (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CAU 1593(T) had the highest similarity to Arenibacterium halophilum (97.5%). The whole genome of strain CAU 1593(T) was 3,979,826 bp with 26 contigs, and the DNA G + C content was 64.3 mol%. The major fatty acid of strain CAU 1593( T) was summed feature 8 (C-18:1 omega 7c/C-18:1 omega 6c). Q-10 was the only respiratory quinone. The polar lipids were composed of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two phosphoglycolipids, an unidentified glycolipid, and an unidentified lipid. Based on the results of chemotaxonomic, phylogenetic, and phenotypic analyses, strain CAU 1593(T) represents a novel species in the genus Arenibacterium, which is named Arenibacterium arenosum sp. nov. The type strain is CAU 1593(T) (= KCTC 82402(T) = MCCC 1K05671(T)).
