Ochratoxin production by the Aspergillus ochraceus group and Aspergillus alliaceus.
Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliac...

متن کاملOCCURRENCE OF A MYCOTOXIN, OCHRATOXIN A, IN WHEAT AND ISOLATION OF OCHRATOXIN A AND CITRININ PRODUCING STRAINS OF PENICILLIUM VIRIDICATUM Ochratoxin A is a metabolite of Aspergillus ochraceus
Ochratoxin A is a metabolite of Aspergillus ochraceus Wilh. (5) and of Penicillium viridicatum Westling (8). It is highly toxic to rats and ducklings and produces liver and kidney damage (6). Both A. ochraceus and P. viridicatum have been isolated from stored grain, and ochratoxin A itself was recently found in corn (7). The presence of this toxin in rolled wheat used as livestock feed is repor...
متن کاملPostharvest production of ochratoxin A by Aspergillus ochraceus and Penicillium viridicatum in barley with different protein levels.
The production of ochratoxin A (OA) in barley by Aspergillus ochraceus and Penicillium viridicatum was measured at 12 and 25 degrees C. The grain had been fertilized with various amounts of nitrogen fertilizer (0, 90, or 240 kg/ha) and contained (at crop maturity) 9.1, 10.4, or 12.0% protein, respectively. The production of OA by both fungi increased as the protein concentration increased. Glut...
متن کاملProduction 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% sucr...
