Fig. 5From: Inhibition of biofilm formation in Mycobacterium smegmatis by Parinari curatellifolia leaf extractsThe effects of 100 μg/ml of the different P. curatellifolia leaf extracts on M. smegmatis biofilm formation. M. smegmatis was incubated with the plant extracts for 72 h at 37 ̊ C. The biofilm mass that formed during the incubation period was stained using crystal violet. The absorbance values of crystal violet are directly proportional to the amount of biofilm that had formed. The dye was extracted using ethanol and quantified spectrophotometrically at 590 nmBack to article page
