Aspergilli as Ochratoxin Producers

Mycologia, 1972
To determine whether ochratoxin is produced by species of Aspergillus other than Asp. ochraceus, 44 strains representative of the 9 spp. composing the Asp. ochraceus group were grown on both pearled wheat and cracked corn in duplicate shaken flasks at 28°C for 5 days. Rice was a poor substrate for ochratoxin production.

Broad-specificity photoelectrochemical immunoassay for the simultaneous detection of ochratoxin A, ochratoxin B and ochratoxin C

Biosensors and Bioelectronics, 2018
A broad-specific photoelectrochemical (PEC) immunosensor was developed for the simultaneous detection of ochratoxin A, ochratoxin B and ochratoxin C (OTA, OTB, OTC) by using the direct growth of CdS nanorods on FTO as the photoelectrode and Au nanoflowers-modified glass carbon electrode (GCE) as the bioelectrode.

Ochratoxins

In this section, ochratoxins are described in general, and their effects on human health and the toxic effects are particularly discussed. Ochratoxins are considered to be among the mycotoxins with significant health implications due to their widespread presence in food and feed.

Targeting Ochratoxin Biosynthetic Genes

2016
The pathway of ochratoxin A (OTA) biosynthesis has not yet been completely elucidated. Essentially, two kind of genes have been demonstrated to be involved in the biosynthesis of OTA. One of them is the nrps gene encoding a non-ribosomal peptide synthetase (NRPS) which catalyzes the ligation between the isocoumarin group, constituting the polyketide ...

Immunotoxic activity of ochratoxin A

Journal of Veterinary Pharmacology and Therapeutics, 2006
Ochratoxin A (OTA) is an immunosuppressant fungal compound, produced by toxigenic species ofAspergillusandPenicilliumfungi in a wide variety of climates and geographical regions. The contamination of food by this mycotoxin takes place primarily during preharvest periods. Almost all types of food can be contaminated.

OCHRATOXIN A IN TURKISH WINES

Journal of Food Biochemistry, 2005
In this research, 47 wine samples produced from 2001 to 2002 harvest period in four Turkish regions were analyzed for the presence of ochratoxin A (OTA). Based on the results, the OTA levels of red wines are generally higher than those of white and rose wines.

Ochratoxin A

2001
Recommendations. Studies should be conduced to clarify the mechanism by which ochratoxin A induces nephhrotoxicity and carcinogenicity. Appropriate sampling procedures should be developed for food commodities likely to be contaminated with ochratoxin A.
