Ultivated saprotrophic microbiota of the scallop Mizuhopecten yessoensis (Jay, 1857) (Mollusca: Bivalvia) sampled in Aniva Bay (Sakhalin Island)
The data on the composition of cultivated saprotrophic bacteria isolated from the internal organs, tissues and cavity fluid of the scallop Mizuhopecten yessoensis (Jay, 1857) collected at one of the sites of mollusk habitat in the Aniva Bay are presented. The study of microbiota of mollusks was conducted from May to September 2011-2013. During the research period, 71 pure bacterial cultures were isolated and tested. The taxonomically isolated microorganisms belonged to 12 genera from 10 families. According to the number of species, two genera dominated among the isolated bacteria - Vibrio and Pseudomonas. The species composition of the isolated saprotrophic microbiota varied from year to year. Pathogenic for the mollusk Vibrio alginolyticus and Vibrio vulnificus were isolated annually.
