Pseudovibrio ascidiaceicola sp nov, isolated from ascidians (sea squirts)

Two bacterial strains, F423 (T) and F10102, were isolated from two ascidians, Polycitor proliferus and Botryllidae sp., respectively, which were collected from a beach on the Boso peninsula in Japan. Cells of both isolates were motile, rod-shaped and formed star-shaped aggregates in the early stage of exponential growth, but were coccoid in stationary growth phase. The results of 16S rRNA gene sequence analysis, fatty acid analysis, DNA-DNA hybridization experiments and physiological and biochemical tests indicated that the two strains were members of a novel species of the genus Pseudovibrio for which the name Pseudovibric, ascidiaceicola sp. nov. is proposed. The type strain is F423 (T) (=NBRC 100514 (T) = AM 15084 (T) =DSM 16392 (T) =KCTC 12308 (T)).
