Impact of hadD deletion on the sensitivity of M. smegmatis to antibiotics and SDS in planktonic cultures.

M. smegmatis strain	Minimal inhibitory concentrationa
	Rifampicin (µg/ml)	Isoniazid (µg/ml)	Ethambutol (µg/ml)	SDS (%)
wt	16.9 ± 4.8	7.1 ± 0.9	3.9 ± 1.2	0.016 ± 0.000
ΔhadD	0.37 ± 0.13	7.7 ± 0.2	3.1 ± 0.0	0.007 ± 0.001
complemented	3.1 ± 0.9	6.4 ± 1.6	3.1 ± 0.0	0.012 ± 0.004

^aMIC values (means ± average deviations) measured by MTT assays were determined as the lowest concentration of compound yielding 99.9% inhibition of the bacterial growth.
