Evaluation of zearalenone, α-zearalenol, β-zearalenol, zearalenone 4-sulfate and β-zearalenol 4-glucoside levels during the ensiling process
(Wageningen Academic Publishers, 2014-03)
Zearalenone-producing Fusarium species can contaminate maize before ensiling and cause reproductive problems in animals. Suspect feeds are only routinely analysed for zearalenone (ZEA), not considering other oestrogenic ...
Zearalenone and its derivatives α-zearalenol and β-zearalenol decontamination by Saccharomyces cerevisiae strains isolated from bovine forage
(MDPI, 2015-08)
Zearalenone (ZEA) and its derivatives are mycotoxins with estrogenic effects on mammals. The biotransformation for ZEA in animals involves the formation of two major metabolites, α- and β-zearalenol (α-ZOL and β-ZOL), which ...
Effect of the combination of crude extracts of Penicillium griseofulvum and Fusarium graminearum containing patulin and zearalenone on rumen microbial fermentation and on their metabolism in continuous culture fermenters
(Taylor & Francis Ltd, 2014-06)
Six single-flow continuous cultures were used to study the effects of the mycotoxins patulin (PAT) and zearalenone (ZEN) alone or in combination on rumen microbial fermentation. In each of the four 7-d periods, the fermenters ...
Estrogenic mycotoxins in surface waters of the rico stream micro-basin, SãO Paulo, Brazil: Occurrence and potential estrogenic contribution
(2020-04-01)
The aim of this study was to assess the occurrence of zearalenone (ZEN) and its metabolites zearalanone (ZAN), α-zearalenol (α-ZEL), β-zearalenol (β-ZEL) α-zearalanol (α-ZAL), and β-zearalanol (β-ZAL) in the surface waters ...
Uma avaliação qualitativa da presença de micotoxinas e micro-organismos toxigênicos em insumos e em cervejas artesanais
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2019-12-06)
Consisting primarily of water, hops, malted and non-malted cereals as well as yeast, beer is one of the most consumed alcoholic fermented beverages in the world. Although there are risk laws that compromise product quality, ...
Biomarcadores sanguíneos de exposição à zearalenona e aplicabilidade na avaliação da eficiência de aditivos antimicotoxinas em suínos e bovinos
(Universidade Federal de Santa MariaBrasilMedicina VeterináriaUFSMPrograma de Pós-Graduação em Medicina VeterináriaCentro de Ciências Rurais, 2020-02-14)
The inclusion of antimycotoxins additives (AMA) in the diet of production animals has been used to avoid mycotoxins exposure. To confirm the efficacy of such products in vivo, measurement of mycotoxins and/or their metabolites ...
Assessment of Mycotoxin Exposure in a Rural County of Chile by Urinary Biomarker Determination
(2021)
Aflatoxin B1 (AFB1), ochratoxin A (OTA), zearalenone (ZEN), and deoxynivalenol (DON) are frequent mycotoxins that may cause carcinogenic, mutagenic, estrogenic, or gastrointestinal effects. The aim of this study was to ...
Presence of multiple mycotoxins and other fungal metabolites in native grasses from a wetland ecosystem in Argentina intended for grazing cattle
(MDPI, 2015-08)
The aim of this study was to evaluate the occurrence of several fungal metabolites, including mycotoxins in natural grasses (Poaceae) intended for grazing cattle. A total number of 72 and 77 different metabolites were ...
