FIGURE 4.
Effects of flagellar biosynthesis on growth with soluble or insoluble electron acceptors. A, insoluble Fe(III) oxide. The wild-type DL-1 strain (WT) and the DL-1 strain containing the complete fgrM gene (+fgrM) were grown in FWA liquid medium containing Fe(III) oxide. Reduction of Fe(III) was monitored by measuring the concentration of Fe(II). B, soluble Fe(III) citrate. The wild-type DL-1 strain and the DL-1 strain containing the complete fgrM gene were grown in FWA liquid medium containing Fe(III) citrate. Reduction of Fe(III) was monitored by measuring the concentration of Fe(II). C, fumarate. The wild-type DL-1 strain and the DL-1 strain containing the complete fgrM gene were grown in NBAF liquid medium. Growth was monitored as A600.
