Decontamination of Fumonisin B1 in maize grain by Pleurotus eryngii and antioxidant enzymes

Abstract

Fumonisin B1 (FB1) is among the most common mycotoxins found in maize kernels and maize productsworldwide. The microbiological process of detoxification and transformation of toxic organic pollutants is a promisingmethod for foodstuffs decontamination. Some basidiomycetes, such as the Pleurotus eryngii species complex,include several important commercial edible varieties that can detoxify polycyclic organic compounds and a rangeof wastes and pollutants. We investigated the potential role of P. eryngii, one of the most consumed mushrooms, inthe decontamination of FB1 in maize. In addition, selected antioxidant enzymes, (soluble peroxidase (POD), catalase(CAT) and ascorbate peroxidase), primarily involved in control of cell hydrogen peroxide levels, and lignindegradation, were analyzed, to evaluate their contributions to the molecular mechanisms of FB1 by P. eryngii. FB1decontamination by P. eryngii and involvement of CAT and POD enzymes in the control of toxic decontaminationlevels of H2O2 were demonstrated. A consistent reduction of FB1 was observed at different incubation times. Theaverage decrease levels of FB1, with respect to the control cultures, ranged from 45 to 61% (RSD < 15%). This studyis a possible eco-friendly approach to reducing this mycotoxin in the feed supply chains.
