Effect of in-house produced enzyme cocktail on E. coli and P. aeruginosa biofilms developed on Foley’s catheter. The panel shows the placement of crystal violet stained pieces cut from Foley’s catheter wherein (ad biofilm produced by E. coli). a Control (untreated); b treated with enzyme cocktail; c treated with heat-inactivated enzymes; d treated with PBS; e control (no biofilm, no enzyme treatment); (fi biofilm produced by P. aeruginosa). f Control (untreated); g treated with enzyme cocktail; h treated with heat-inactivated enzymes; i treated with PBS. j FE-SEM images of the (untreated) biofilms of E. coli and k P. aeruginosa established on Foley’s catheter, l disrupted E. coli and m P. aeruginosa biofilms after treatment with in-house produced enzyme cocktail. No difference was observed between heat inactivated, PBS treated and positive controls
