Abstract

A method has been found for the inhibition of microbial biofilm on surfaces in contact with systems, such as aqueous systems. In accordance with the method, an effective amount of a modified starch polymer is fed to the system water. The modified starch polymer may be a cationic quaternary ammonium starch.
