<p>Fumonisin B1 (FB1) is among the most common mycotoxins found in maize kernels and maize products<br>
worldwide. The microbiological process of detoxification and transformation of toxic organic pollutants is a promising<br>
method for foodstuffs decontamination. Some basidiomycetes, such as the Pleurotus eryngii species complex,<br>
include several important commercial edible varieties that can detoxify polycyclic organic compounds and a range<br>
of wastes and pollutants. We investigated the potential role of P. eryngii, one of the most consumed mushrooms, in<br>
the decontamination of FB1 in maize. In addition, selected antioxidant enzymes, (soluble peroxidase (POD), catalase<br>
(CAT) and ascorbate peroxidase), primarily involved in control of cell hydrogen peroxide levels, and lignin<br>
degradation, were analyzed, to evaluate their contributions to the molecular mechanisms of FB1 by P. eryngii. FB1<br>
decontamination by P. eryngii and involvement of CAT and POD enzymes in the control of toxic decontamination<br>
levels of H2O2 were demonstrated. A consistent reduction of FB1 was observed at different incubation times. The<br>
average decrease levels of FB1, with respect to the control cultures, ranged from 45 to 61% (RSD < 15%). This study<br>
is a possible eco-friendly approach to reducing this mycotoxin in the feed supply chains.</p>
