Figure 5

Images of the effects of the extract and B1 on biofilm structure of P. aeruginosa viewed under a Nikon light microscope at 40x magnification. (a) Cells treated with the extract had a dispersed biofilm structure. (b) Cells treated with B1 had no biofilm structure. (c) The untreated cells showed a compact biofilm structure.
