High Production of Kojic Acid Crystals by <i>Aspergillus parasiticus</i> UNBF A12 in Liquid Medium

Abstract

The crystalline compound produced in large quantity in liquid medium by Aspergillus parasiticus UNBF A12, a high aflatoxin-producing strain isolated from the air in the Federal District of Brazil, was identified as kojic acid. The effect of pH on the production of crystalline kojic acid and aflatoxins by the strain was studied. Fourteen single spore isolates were evaluated for their capacity to produce kojic acid crystals and aflatoxins.
