The industrial production of kojic acid are fermented by fungi, mostly Aspergillus species that can be easily isolated and identified by the presence of an acid-producing enzyme called tyrosinase to form this acid, it’s from the chelating agent of different fungi, such as Aspergillus oryzae, Aspergillus parasitica, Aspergillus flavus, etc. Among the most efficient kojic acid producers are Aspergillus flavus number 7 and Aspergillus oryzae.
