Magnetic hyperbranched molecularly imprinted polymers for selective enrichment and determination of zearalenone in wheat proceeded by HPLC-DAD analysis.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2020
A novel magnetic surface molecular imprinted polymers with 2, 4, 6-trisacrylamido-3, 5-triazine (TAT) as a functional monomer was successfully synthesized and used for the enrichment and determination of zearalenone.

Effects of Processing on Zearalenone

2002
Zearalenone (ZEN), a common contaminant of all major cereal grains worldwide, is produced by some plant pathogenic molds including Fusarium graminearum and F. culmorum. The biological activity of this mycotoxin is mainly attributed to its estrogenic activity that modulates/disrupts endocrine function in animals and possibly humans.

Urinary zearalenone measured with ELISA as a biomarker of zearalenone exposure in pigs

Mycotoxin Research, 2014
The suitability to assess zearalenone (ZEA) exposure in pigs of a commercial ELISA kit for ZEA analysis in urine was tested. A daily dose of 0, 5, 10, 20 and 40 μg synthetic ZEA per kilogram BW was administered via the feed to four gilts per dose group, and after 3 and after 7 days of ZEA intake, urine samples were assayed with the ELISA which has a ...

[Zearalenone in food].

Mycotoxin research, 2013
The research project "Methods of Analysis and occurrence of important Fusarium toxins (deoxynivalenol and zearalenone) as well as the intake of these toxins by the German consumer" supported by the Federal Ministry of Consumer Protection, Food and Agriculture (BMVEL) is processed by the institutions mentioned above. This work represents a comprehensive

Effect of zearalenone on dairy cows

American Journal of Veterinary Research, 1986
SUMMARY Doses of 99% pure zearalenone (0.0, 31.25, 62.5, 125.0, 250.0, or 500.0 mg) in gelatin capsules were given once a day per os to 18 nonpregnant, nonlactating, multiparous dairy cows for 2 consecutive estrous cycles. There was no effect (P < 0.10) on serum progesterone concentrations, rbc, wbc, pcv, hemoglobin, and estrous cycle length ...

Occurrence of zearalenone in maize

Mycotoxin Research, 1993
The occurrence of zearalenone in whole plants and parts of maize usually used for silage making was investigated during the cultivation period of the crop.Zearalenone was detected upto several hundreds of μg/kg DM, that mainly accumulated at the end of the ripening process thus contaminating the silages subsequently.

Phosphorylation of Zearalenone retains its toxicity

Journal of Agricultural and Food Chemistry
ABSTRACTMicrobial biotransformation of Zearalenone (ZEN) is a promising deactivation approach. The residual toxicity and stability of Zearalenone-14-phosphate (ZEN-14-P) and Zearalenone-16-phosphate (ZEN-16-P), two novel microbial phosphorylation products of ZEN, remain unknown.We investigated the cytotoxicity, oxidative stress, pro-inflammatory, and ...

[Biotransformation of zearalenone].

Wei sheng wu xue bao = Acta microbiologica Sinica, 1992
The conversion of Zearalenone by some strains of microorganisms was investigated. When the selective strains of Rhodotorula sp., Arthrobacter sp., Saccharomyces sp., and Candida sp. were incubated by shaking or standing at 28 degrees C for 72 h with an alcoholic solution of Zearalenone as the substrate at a concentration of 2-10 mg/ml ethanol (50-100 ...

A novel zearalenone lactonase can effectively mitigate zearalenone-induced reproductive toxicity in gilts

Toxicon
Zymdetox Z-2000 is a novel zearalenone (ZEN) lactonase produced by Bacillus subtilis that can biodegrade ZEN to hydrolyzed ZEN and decarboxylated hydrolyzed ZEN with much lower estrogenic activity. This study aims to evaluate the efficacy of Zymdetox Z-2000 in mitigating the adverse effects of ZEN on the growth performance and reproductive health of ...
