International Journal of Molecular Sciences. 13:13867-13880. DOI:10.3390/ijms131113867. Interpretive Summary: Kojic acid is a natural compound commonly produced by a number of fungi. One fungus, Aspergillus oryzae, is commonly used to produce a variety of consumable products, such as soy sauce, miso, sake and rice wine. Large quantities of kojic acid are produced as a by-product of these fermentative processes. Thus far, kojic acid has been widely used as a food additive, to prevent browning, and in cosmetics, for skin depigmentation, such as “age spots.” ARS scientists have discovered, yet, another potential use for kojic acid. In this report we show that adding small amounts of kojic acid can improve the antifungal activity of certain commercial products used to kill fungi, both in agriculture and medical or veterinary situations. Since kojic acid is considered a safe compound, it shows promise as a supplement to improve drugs and fungicides for control of problematic fungi.
Technical Abstract: Kojic acid (KA), a natural by-product of fungal fermentation, is a commonly used food and cosmetic additive. We show that KA increases activity of amphotericin B and strobilurin, medical and agricultural antifungal agents, respectively, possibly targeting the fungal antioxidative system. KA shows promise as a chemosensitizing enhancer of antimycotic activity.
