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 کاملInhibitory Effect of Essential Oils on Aspergillus ochraceus Growth and Ochratoxin A Production
Ochratoxin A (OTA) is a mycotoxin which is a common contaminant in grains during storage. Aspergillus ochraceus is the most common producer of OTA. Essential oils play a crucial role as a biocontrol in the reduction of fungal contamination. Essential oils namely natural cinnamaldehyde, cinnamon oil, synthetic cinnamaldehyde, Litsea citrate oil, citral, eugenol, peppermint, eucalyptus, anise and...
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...
متن کاملProduction of ochratoxin A by Aspergillus ochraceus NRRL-3174 before and after exposures to 60Co irradiation.
Spores from the toxigenic organism Aspergillus ochraceus NRRL-3174 were exposed to specific levels of gamma irradiation and then allowed to germinate on selected media. Increases in ochratoxin A production by irradiated, compared to non-irradiated, spores were observed after inoculation of spores onto a cracked red wheat or into a synthetic liquid medium. Variations in daily ochratoxin producti...
متن کاملA Saccharomyces cerevisiae Wine Strain Inhibits Growth and Decreases Ochratoxin A Biosynthesis by Aspergillus carbonarius and Aspergillus ochraceus
The aim of this study was to select wine yeast strains as biocontrol agents against fungal contaminants responsible for the accumulation of ochratoxin A (OTA) in grape and wine and to dissect the mechanism of OTA detoxification by a Saccharomyces cerevisiae strain (DISAABA1182), which had previously been reported to reduce OTA in a synthetic must. All of the yeast strains tested displayed an a...
