The effect of the different concentrations of the ethanol extract on M. smegmatis biofilm formation. M. smegmatis was incubated in different concentrations of the ethanol extract of P. curatellifolia leaf powder for 72 h at 37 ̊ C. The biofilm mass that formed during the incubation period was stained using crystal violet staining which was quantified spectrophotometrically at 590 nm. The error bars indicates the standard deviation from mean (n = 4). Dunnet’s multiple comparison test was used to compare columns using graph pad prism 5 software. The asterisks (*) indicate statistical significant differences with the growth control (media + cells) * < 0.05 *** < 0.0001
