  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 tannin biofilm control agent is fed to the system water. The modified tannin biofilm control agent comprises a reaction product of an amine, an aldehyde and tannin and provides a good environmental profile.
