Sodium circulation in Vibrio parahaemolyticus was investigated. We observed respiration-driven Na+ extrusion from cells by using a Na+ electrode. The Na+ extrusion was intensive to a proton conductor, carbonyl cyanide m-chlorophenylhydrazone, and sensitive to a respiratory inhibitor, CN-. These results support the idea of the existence of a respiratory Na+ pump in V. parahaemolyticus. The respiration-driven Na+ extrusion was observed only under alkaline conditions.
