Production of ochratoxin A by Aspergillus ochraceus isolated in Japan from moldy rice. 1970

M Yamazaki, and Y Maebayashi, and K Miyaki

A simple thin-layer chromatography-fluorodensitometric method for quantitative analysis of ochratoxin A was developed. This method proved to be of use in investigating the production of the toxin and the nutritional factors affecting the toxin production by two strains of Aspergillus ochraceus isolated from moldy rice in Japan. These fungi produced large amounts of ochratoxin A in a nutrient solution containing 1% l-phenylalanine and 2% yeast extract.
