Occurrence of Ochratoxin A in Grape Juice of Iran
Ochratoxin A (OTA) is one of the most important mycotoxins that contaminate a broad range of agricultural and food products. In this study, the occurrence of OTA in available brands of grape juice in Iran purchased from retail outlets or producer were determined for the first time using high-performance liquid chromatography (HPLC) with immunoaffinity columns(IAC) as the clean-up step. The aver...

متن کاملOchratoxin A Producing Fungi, Biosynthetic Pathway and Regulatory Mechanisms
Ochratoxin A (OTA), mainly produced by Aspergillus and Penicillum species, is one of the most important mycotoxin contaminants in agricultural products. It is detrimental to human health because of its nephrotoxicity, hepatotoxicity, carcinogenicity, teratogenicity, and immunosuppression. OTA structurally consists of adihydrocoumarin moiety linked with l-phenylalanine via an amide bond. OTA bio...
متن کاملFilamentous fungi producing ochratoxin a during cocoa processing in Cameroon.
Ochratoxin A (OTA) is the main mycotoxin occurring in cocoa. A study was conducted in Cameroon to assess how filamentous fungi and toxigenesis were affected by the type of cocoa post-harvest treatment (boxes or heaps). The filamentous fungi isolated were almost identical when fermentation was carried out in boxes or heaps, with the presence of abundant black Aspergillus filamentous fungi: A. ni...
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...
