Effects of pduT mutations on the growth of a Salmonella PduA-S40L mutant on 1,2-propanediol minimal medium. All strains were grown on 1,2-PD minimal medium supplemented with limiting B₁₂ (25 nM) as described in the Methods section. Growth assays were performed three or more times with similar results in a microplate reader. The error bars represent one standard deviation and are based on three biological replicates.
