Aquimarina versatilis sp. Nov., isolated from seashore sand, and emended description of the genus Aquimarina

Strain CBA3207^T, a novel Gram-stain-negative, aerobic and rod-shaped bacterium, was isolated from the seashore sand of Jeju island in South Korea. Strain CBA3207^T grew optimally at 25–30 °C and pH 7.0–7.5 with 3.0–4.0% (w/v) NaCl. It was catalasepositive, oxidase-negative, and hydrolysed starch, gelatin, and Tweens 20, 40 and 80. The 16S rRNA gene sequence of strain CBA3207^T showed 96.0, 95.6, 95.6, 95.5 and 95.5% similarity to that of Aquimarinamytili PSC33^T, Aquimarinaagarivorans HQM9^T, Aquimarinalatercula DSM 2041^T, Aquimarinaintermedia KMM 6258^T and Aquimarinaamphilecti 92V^T, respectively. The major fatty acids were iso-C_{15 :0}, iso-C_{17 :0} 3-OH, iso-C_{15 :1} G and summed feature 9 (10-methyl C_{16 :0} and/or iso-C_{17 :1}ω9c). The major respiratory quinone was menaquinone-6, and the major polar lipids were phosphatidylethanolamine, an unidentified aminolipid and six unidentified lipids. The G+C content of the genomic DNA was 38.8 mol%. Based on phenotypic, genotypic and phylogenetic analyses, strain CBA3207^T represents a novel species in the genus Aquimarina, for which the name Aquimarinaversatilissp. nov. is proposed. The type strain is CBA3207^T (=KACC 17666^T=JCM 19528^T).
