Abstract: This invention relates to methods to reduce the levels of contaminants in effluent produced in industrial operations, e.g., refinery operations. In particular, the invention relates to method to reduce the level of organic contaminants in industrial effluent wherein said effluent lacks sufficient dissolved oxygen to support enzymatically-catalyzed removal of organic contaminants comprising adding to the effluent one or more enzymes in an amount effective to reduce the level of organic contaminants in said effluent, wherein said enzymes require oxygen for enzymatic activity; and adding an in situ source of dissolved oxygen.
