Anti-biofilm activity of nisin and polymyxins against P. aeruginosa: Inhibition of biofilm formation of P. aeruginosa PA-01 a) in the presence of nisin (1/3× MIC), colistin (1/2×, 1/5× MIC) and combinations thereof and b) in the presence of nisin (1/4× MIC) and polymyxin B (1/2×, 1/5× MIC) and combinations thereof, when assessed in microtiter plates and subjected to crystal violet (CV) staining for the detection of biofilm formation.
