sp. nov., a marine bacterium isolated from coastal seawater.

A novel Gram-negative, aerobic, motile, rod-shaped, beige-pigmented bacterium, strain ARW1-2F2, was isolated from a seawater sample collected from Roscoff, France. Strain ARW1-2F2 was catalase-negative and oxidase-positive, and grew under mesophilic, neutrophilic and halophilic conditions. The 16S rRNA sequences revealed that strain ARW1-2F2 was closely related to LFT 1.7 and RW17-10(95.8 and 95.5 % gene sequence similarity, respectively). The genome of strain ARW1-2F2 was sequenced and had a G+C content of 28.7%. Two different measures of genome similarity, average nucleotide identity based on blast and digital DNA-DNA hybridization, indicated that strain ARW1-2F2 represents a new species. The predominant fatty acids were C ω7/C ω6 and C ω7/C ω6. The results of a polyphasic analysis supported the description of strain ARW1-2F2 as representing a novel species of the genus , for which the name sp. nov. is proposed with the type strain ARW1-2F2 (DSM 29169=KCTC 52423).
