Abstract:
1. A method of reducing oxygen from an aqueous medium of an electrochemical process, comprising: combining in an aqueous medium an oxidase, an oxidase substrate, and a catalase to so form a test medium for use in an electrochemical process; wherein the oxidase produces from the oxidase substrate and dissolved oxygen in the test medium a reaction product and hydrogen peroxide; wherein at least one of the oxidase and the oxidase substrate is selected such that the reaction product maintains at least one of pH of the test medium, activity of an enzyme present in the electrochemical process, and reactivity of the reaction product in the electrochemical process over a predetermined test period; incubating the test medium for a time sufficient to deplete the test medium of dissolved oxygen while the test medium is exposed to ambient air; and performing the electrochemical process within the predetermined test period while the test medium is exposed to atmospheric oxygen.
