The white koji fungus, Aspergillus luchuensis mut. kawachii, is an industrially important microorganism used in the production of shochu, a traditional distilled alcoholic beverage indigenous to Japan. It secretes large amounts of citric acid that can prevent the growth of contaminating microbes during the fermentation process. The citrate exporter CexA plays a key role in the overproduction of citric acid. The photograph shows the vegetative hyphae of A. luchuensis mut. kawachii.
