Claim:
A method of reducing or inhibiting the growth of aerobic microbes in a preparation comprising the step of incorporating into said preparation a polypeptide that can oxidize at least maltose, wherein said polypeptide is a recombinantly-produced polypeptide comprising a polypeptide encoded by a recombinant DNA sequence that hybridizes with the nucleic acid sequence set forth in SEQ ID NO:30 under stringent conditions comprising (1) hybridization at 65° C. for at least 14 hours in a buffer containing 1×Denhardt's solution, 2×SSC, 0.1% dextran sulphate, and 50 μg/ml denatured salmon sperm DNA, followed by (2) two washes at 65° C. for 10 minutes in 2×SSC, 0.1% SDS, and followed by (3) two washes at 65° C. for 10 minutes in 1×SSC, 0.1% SDS.
