Figure 5

MmpL11 is essential for Mtb to grow in fatty acid rich conditions: (A) Bacterial growth in the presence of different concentrations of methyl palmitoleate with (solid symbols) and without ADC (open symbols) for 15 days is depicted as % relative growth mean ± SD of triplicate wells of one of three experiments. Values are represented as ratio of mean O.D. at 600 nm in methyl ester of fatty acids relative to no treatment ± SD. (B) The bacterial numbers at 0, 1, and 3 days of growth in media containing 33.5 µM methyl-palmitoleate for the Mtb strains is shown as mean cfu/ml ± SD. (C) Growth in the presence of methyl oleate or methyl elaidate with (solid symbols) and without ADC (open symbols) is depicted as the average % relative growth mean ± SD of triplicate wells. (D) Quantitation of CL in the lipids of Mtb grown in methyl-oleate for 24 hr by densitometry. The relative amount of CL is represented as mean ± SD for a representative of 2 biological replicate experiments. (E) Intracellular growth of Wt, ΔM11 and Comp grown in oleic acid pre-treated differentiated THP1 cells is shown as cfu/ml ± SD of triplicate wells of one of the two experiments. (F) A representative image of the bacterial colonies from oleic acid treated THP1 cells at day 1 p.i. for the 3 Mtb strains.
