Oxidation of acetophenone by Aspergillus species and their possible contribution to Katsuobushi flavor.

Acetophenone was converted to phenol by A. glaucus MA0200. Production of phenol, which has a pungent flavor, seemed to give a contrary effect on the creation of flavor of molded Katsuobushi. Production of phenol is the process of degradation of acetophenone, also with a pungent flavor. It would play a role in the decreasing of the pungent flavor of Katsuobushi.
