Abstract

A Gram-stain-negative, strictly aerobic, yellow-pigmented, rod-shaped and -acylhomoserine lactone-degrading bacterium, designated strain Th78, was isolated from the intestine of a cultured flounder (). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain Th78 belonged to the genus (family ) and showed the highest 16S rRNA gene sequence similarity to H35 (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-C 3-OH, iso-C G and iso-C 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 Th78 was 31.5 mol%. On the basis of polyphasic analysis, strain Th78 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is Th78 ( = JCM 18634 = KCTC 32142 = DSM 26285). Emended descriptions of the genus and are also proposed.
