Production of ochratoxin A by Aspergillus ochraceus in a semisynthetic medium.
Aspergillus ochraceus NRRL 3174 produced 29 mg of ochratoxin A per 100 ml of nutrient medium consisting of 4% sucrose and 2% yeast extract. Ochratoxin A was the sole metabolite present in the chloroform extracts of the growth medium. Trace amounts of ochratoxin B were produced in a 1% yeast medium, and a comparatively large amount of ochratoxin B was produced in media containing 16 and 32% sucrose.
