Properties of the flagella and swimming of B. clausii KSM-K16. Cells were grown at 30°C in alkaline complex medium (pH 9.0 and 230 mM Na+). (A) Stained flagellae of wild-type B. clausii KSM-K16. Cells were stained with staining solution that contained 5% (wt/vol) tannic acid as described in Materials and Methods. (B and C) The pH values used in the particular assay are designated by symbols that are indicated. (B) The swimming speed of wild-type B. clausii in alkaline complex medium as a function of the sodium concentration and pH. The swimming speed was assayed at various concentrations of sodium as described in Materials and Methods. (C) Effect of EIPA and CCCP on the swimming speed of wild-type B. clausii. Swimming speeds were measured at various concentration of EIPA (Left) or CCCP (Right) in alkaline complex medium containing 230 mM sodium.
