MtH37Rv 9.0 (0.01) 10.7 (0.74)
MtΔP27 15.3 (0.54)* 11.6 (0.34)
MtΔP27+P27 15.3 (0.54)* 12.3 (1.90)

  1. §Rates are expressed as nanograms of malachite green decolorized in 10 min per milliliter of culture at 37°C. Values show means +/- standard deviations of duplicates. All data are representative of three independent experiments. *Significantly different from values of H37Rv (p < 0.005).
