Abstract: A culture system for culturing a microaerophilic or an anaerobic microorganism is provided. The culture system can include effective amounts of i) an enzyme of an oxidoreductase family and ii) a substrate for said enzyme, a container, and a predetermined volume of aqueous medium that supports growth of said anaerobic or microaerophilic microorganism. The enzyme can be selected from a group consisting of ascorbic acid oxidase and laccase. The effective amounts are effective to deplete dissolved oxygen in the predetermined volume to a concentration that facilitates growth of a microaerophilic microorganism or an obligately-anaerobic microorganism. A method of using the system is also provided.
