Mycelia of citric acid-producing Aspergillus niger WU-2223L show cyanide-insensitive respiration catalyzed by alternative oxidase. In this study, the constitutive expression of alternative oxidase gene (aox1) even at the stage of single-cell conidium in A. niger WU-2223L was found using the visual expression analysis system of aox1 with green fluorescent protein under microscopy observation.
