ABSTRACT:
A method of killing and inhibiting the growth of microorganisms in industrial process streams comprises the addition of an enzymatically catalyzed biocide system utilizing a microbial or plant dehydrogenase enzyme such as peroxidase or laccase in the presence of an oxidant such as hydrogen peroxide or oxygen to oxidize phenolic compounds found in or added to the process streams to produce oxidation products that are toxic to microorganisms.
