Abstract
A method is disclosed for controlling biofouling in an aqueous medium by treating the aqueous medium with an oil-in-water emulsion comprising an antimicrobial oil phase and at least one emulsifier. This method efficiently controls biofouling in the aqueous medium by specifically targeting the antimicrobial oil phase directly to biofilms, cell surfaces and cell aggregates in a concentrated form.
