Production of ochratoxin A by Aspergillus ochraceus isolated in Japan from moldy rice.
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 so...
متن کاملOchratoxin 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...

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...

15 صفحه اولNew ochratoxin A or sclerotium producing species in Aspergillus section Nigri
Aspergillus section Nigri includes some of the most important species for biotechnology and its species are of widespread occurrence. During our surveys of various food products and tropical soil we isolated several aspergilli belonging to section Nigri. In this paper, four new sclerotium and/or ochratoxin A producing species belonging to this section are proposed. In addition, based on a polyp...
