Taxonomic Study of a Marine Bacterium Producing Guluronate Lyase

A marine bacterium that secretes a novel guluronate lyase that is heat- and denaturants-durable, has been isolated from the intestine contents of a red sea bream, Pagrus major. To characterize this marine bacterium, we attempted taxonomic study with respect to eleven characteristics used for the specification with an electron microscope photograph. The findings showed that the marine bacterium is a member of the genus Vibrio.
