| Applications | Uses: A toxic metabolite of Aspergillus ochraceus, Aspergillus sulphureus, Aspergillus melleus, and Penicillium viridicatum molds. Ochratoxins are natural contaminants of corn, peanuts, storage grains, cottonseed, and other decaying vegetables, Used as an experimental teratogen and carcinogen, [Merck Index], Experimentally as teratogen and carcinogen, Ochratoxins, Human exposure occurs mainly through consumption of improperly stored food products, particularly contaminated grain and pork products, as well as coffee, wine grapes and dried grapes. (L1939), General Manufacturing Information: Dichlorvos at 1 mg, 100 mL of yeast extract-sucrose medium decreased production of ochratoxin b in cultures of Aspergillus ochraceus by 50%, but growth of culture was not affected. Concentrations of 10-30 mg, 100 mL, dichlorvos decreased production of ochratoxin b 50-90%, growth was decreased 9-21%., Isolations: van Walbeek et al, Can J Microbiol 14, 131 (1968), Shotwell et al, Appl Microbiol 17, 765 (1969), Nesheim, J Assoc Offic Anal Chem 52, 975 (1969), Natori et al, Chem Pharm Bull 18, 2259 (1970)., As these molds occur widely, some toxins have been found as natural contaminants on corn, and other decaying vegetation., Ochratoxion B ..., is, the less toxic ..., non-chlorinated, derivative of ochratoxin A., Two strains of Aspergillus ochraceus isolated from country cured hams produced ochratoxin B on rice, defatted peanut meal, and country cured ham. |
