Mitigation of nivalenol using alcoholic fermentation and magnetic field application

This study aimed at evaluating mitigation of nivalenol (NIV) in alcoholic fermentation with magnetic field application (MF). Mitigation was related to both the glutathione (GSH) redox molecule and the enzyme peroxidase (PO), which were synthesized by Saccharomyces cerevisiae US-05. Conditions under evaluation were NIV (0.2 mu g mL(-1)), MF application (35 mT) and simultaneous use of mycotoxin and MF. The GSH content and the PO activity were increased when the culture contained NIV and the alcohol profile was altered after 48 h of fermentation. At the end of the alcoholic fermentation, NIV was mitigated by 56.5%. Therefore, this process is a promising method to reduce contamination by NIV, although the mycotoxin affects the chemical characteristics of the final product.

Automated summary

This study aimed to evaluate the mitigation of NIV in alcoholic fermentation using MF. The GSH content and PO activity were increased with the presence of NIV, and after 48 hours of fermentation, the alcohol profile was altered. By the end of the fermentation, NIV was mitigated by 56.5%. This method shows promise in reducing NIV contamination, although the mycotoxin can affect the chemical characteristics of the final product.
