abstract= A Gram-stain-negative, strictly aerobic, yellow-pigmented, rod-shaped and N-acylhomoserine lactone-degrading bacterium, designated strain Th78T, was isolated from the intestine of a cultured flounder (Paralichthys olivaceus). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain Th78T belonged to the genus Flaviramulus (family Flavobacteriaceae ) and showed the highest 16S rRNA gene sequence similarity to Flaviramulus basaltis H35T (96.70 %). Optimal growth occurred in the presence of 2–3 % (w/v) NaCl, at pH 7.0–8.0 and at 28 °C. The major fatty acids were iso-C15 : 0 3-OH, iso-C15 : 1 G and iso-C17 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and three unidentified polar lipids. Menaquinone 6 (MK-6) was the only respiratory quinone. The DNA G+C content of strain Th78T was 31.5 mol%. On the basis of polyphasic analysis, strain Th78T is considered to represent a novel species of the genus Flaviramulus , for which the name Flaviramulus ichthyoenteri sp. nov. is proposed. The type strain is Th78T ( = JCM 18634T = KCTC 32142T = DSM 26285T). Emended descriptions of the genus Flaviramulus and Flaviramulus basaltis are also proposed.,
