ISOLATION OF THE POLAR AND LATERAL FLAGELLUM-DEFECTIVE MUTANTS IN VIBRIO-ALGINOLYTICUS AND IDENTIFICATION OF THEIR FLAGELLAR DRIVING ENERGY-SOURCES

Vibrio alginolyticus has two types of flagella (polar and lateral) in one cell. We isolated mutants with only a polar flagellum (Pof(+) Laf( -)) or only lateral flagella (Po- Laf(+)). Using these mutants, we dem onstrated that the energy sources of the lateral and polar flagellar m otors in V. alginolyticus are H+ and Na+ motive forces, respectively, as in the related species V. parahaemolyticus.
