<i>Aestuariibius violaceus</i> sp. nov., isolated from a marine limpet <i>Cellana toreuma</i>.

ABSTRACT: A novel bacterium, designated strain 2305UL40-4^T, was isolated from Cellana toreuma (a Korean limpet) collected from Ulleung Island, Republic of Korea. The cells were Gram-stain-negative, aerobic, rod-shaped (0.5-0.9 µm×1.5-2.2 µm) and non-motile. Growth was observed at 22-36 °C (optimum 25-30 °C), pH 6-8 (optimum pH 7) and in the presence of 0.5-4.0% (w/v, optimum 2.0%) NaCl. The 16S rRNA gene sequence analysis revealed that strain 2305UL40-4^T shared 97.4% similarity with Aestuariibius insulae DBTF-13^T. The average nucleotide identity value between the two strains was 76.5%, and the digital DNA-DNA hybridization value was 19.0%. Both values are well below the species delineation thresholds.
