Figure 2. Effect of B. lanzan, ciprofloxacin (CIPRO) and gentamicin (GENTA) at sub-MIC concentrations (1/2MIC, 1/4MIC and 1/8MIC) on biofilm formation of E.coli and P. aeruginosa. Biofilm formation was assessed by the colorimetric crystal violet-based technique. The results are expressed as percentage of biofilm inhibition with respect to untreated control. Values are expressed as Mean±SE.
