- Abstract
During an investigation of the biodiversity of the cultivable bacterial community associated with paralytic shellfish poisoning toxin-producing marine dinoflagellate, <italic>Alexandrium minutum</italic> a novel algal-associated bacterium, designated strain AT2-AT was isolated. 16S rRNA gene sequence similarity analysis showed that the strain is a member of the genus <italic>Ponticoccus,</italic> with high sequence similarity to <italic>Ponticoccus litoralis</italic> DSM 18986T (97.9%) and <italic>Ponticoccus</italic><italic>lacteus</italic> JCM 30379T (96.0%). However, based on the data obtained for the physiological and biochemical characteristics, and low level of DNA-DNA relatedness analysis, the strain could be genotypically and phenotypically differentiated from two type strains of the genus <italic>Ponticoccus</italic>. Therefore, this algal-associated bacterial strain is concluded to represent a novel species of the genus <italic>Ponticoccus</italic>, for which the name <italic>Ponticoccus alexandrii</italic> sp. nov. is proposed. The type strain is AT2-AT (CCTCC AB 2017228 T <bold>=</bold> KCTC 52626 T<bold>)</bold>.
