Aspergilli as Ochratoxin Producers
Mycologia, 1972To 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.

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.

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
2016The 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, 2006Ochratoxin 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.

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.

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.

, 2006 Cette présentation montre les résultats majeurs obtenus au cours d'un travail R&D portant sur la contamination du café par l'ochratoxine A (OTA) et les moisissures toxinogènes responsables. Partant de l'hypothèse que les contaminations se développent essentiellement au cours du premier traitement post-récolte au cours duquel, la teneur en eau du ...

Ochratoxin A and Related Mycotoxins
2014Ochratoxins are toxins produced by fungal species belonging not only to Aspergilli but also to Penicillia with ochratoxin A (OTA) being the main toxin of the group followed by ochratoxin B (OTB) and ochratoxin C (OTC). These mycotoxins are formed in a variety of plant products as well as in some animal-derived products following fungal invasion.
