摘要：A plasmid-cured strain of the marine Vibrio alginolyticus 138-2 retains a respiration-drive Na+ pump. Examinations of several strains of V. alginolyticus and V. parahaemolyticus revealed that these marine Vibrio always possessed the respiration-driven Na+ pump irrespective of the presence or absence of plasmids. These results strongly suggested that the genes for the Na+ pump were encoded by chromosomal DNA.
