The effects of selected concentrations of enzymes (a) lyticase (2.5 units mL− 1) and (b) β-glucosidase (0.05 units mL− 1) against biofilm embedded P. aeruginosa strains with different gene profiles that were determined by colony counting technique. Error bars represent standard deviation (SD). Asterisks indicate the statistically significant difference before and after enzyme treatment (*P < 0.05)
