Characterization of the M. tuberculosis Δppe37 mutant. a Growth of avirulent Mtb strain mc26206 (wt; circles) and Δppe37 mutant (triangles) in HdB minimal medium with 10 µM hemin (red) or 2.5 µM human hemoglobin (blue). b Growth of avirulent Mtb strain mc26206 (wt; black circles) and Δppe37 (red triangles) in HdB minimal medium with 0.5% bovine serum albumin and 10 µM hemin. All media contained 20 µM of 2,2′-dipyridyl to prevent utilization of trace iron. Error bars represent standard errors of mean values of biological triplicates.
