Reduction of Fe3+ (A) and NAG metabolism (B) by WT, ∆nuoN∆nqrF1 and single mutants with 10 mM NAG as the carbon source. Reduction of Fe3+ by (C) and d,l-lactate metabolism (D) by WT, ∆nuoN∆nqrF1 and single mutants with 10 mM d,l-lactate as the carbon source. Points represent an average of multiple replicates and error bars represent standard deviation (n = 3).
