Impact of Pediococcus pentosaceus strain L006 and its metabolites on fumonisin biosynthesis by Fusarium verticillioides

Yeast and bacteria from ensiled high moisture maize grains as potential mitigation agents of fumonisin B1

“…Such a decrease was, however, not found by Uegaki et al and Latorre et al , who indicated stable free FB 1 concentrations in whole plant silages, even after 8 months of storage. As corroborated by numerous publications, one of the main processes that could explain the free FB 1 decrease results from adsorption mechanisms . Fumonisin adsorption mechanisms which generate FB 1 complexed forms may take place during silage fermentation with the matrix or fermentative bacterial peptidoglycans .…”

“…These biological treatments include both adsorption and microbial degradation . Adsorption can result from the binding of FB 1 with cell wall components of microorganisms, which is largely documented in the literature . Moreover, during the biological postharvest treatments of maize, FB 1 binding can also involve the formation of covalent bonds with maize components or the physical entrapment of the toxin into macromolecules such as starch .…”

Factors controlling mycotoxin contamination in maize and food in the Hebei province, China

“…3a). According to the code of practice for the prevention and reduction of mycotoxin contamination in cereals (CAC 2003), all these agricultural practices adopted by farmers for raising maize yield can also reduce the spread and survival of fungi in the field and then mitigate the mycotoxin contamination of maize. Adversely, to raise the maize yield, farmers generally applied more than the recommended amount of pesticide, potentially posing an environmental risk.…”

“…Ongoing research on the control of mycotoxin contamination has not only advanced the techniques of mycotoxin detection and detoxication (Alberts et al 2009;Heinl et al 2010;Pereira et al 2011;Dalié et al 2012), but also increased the information concerning environmental factors that affect fungal colonization and subsequent mycotoxin production in oil-rich agricultural crops including maize pre-and postharvest (Paterson and Lima 2010;Wu et al 2011;Hell and Mutegi 2011;Chang et al 2012). It has been confirmed that mycotoxin contamination is a generally climate-dependent, plant and storage-associated problem, associated with many factors (e.g., biological factors, harvesting, storage and processing conditions, moisture content), insect damage, and preand post-harvest handling (Gnonlonfin et al 2013).…”

Furthermore, various best preventive practices and management systems are already in use or being developed, such as pre-harvest hazard analysis and critical control points programs for controlling aflatoxin in maize in Southeast Asia (FAO/IAEA 2001), code of practice for the prevention and reduction of mycotoxin contamination in cereals (CAC 2003). Recently, the code of practice and measures to control fumonisins in maize (discussion paper) was also released (FAO/WHO 2013).…”
