Résumé : Wastewaters produced by industry and municipalities contain numerous synthetic compounds in varying concentrations. Micro pollutants can be defined as inorganic and organic substances present at low concentrations (pg/L to ng/L) in the environment having adverse consequences for living organisms at these low concentrations. To date, an effective and sustainable global strategy against this insidious contamination of aquatic environments barely exists. Source controls and technical systems, such as wastewater treatment plants, function only as partial barriers or not at all. In this presentation, we present an efficient strain of white rot fungi producing high amounts laccase capable of transforming the tested micro pollutants (bisphenol A, nonylphenols and triclosan). The enzymes are successfully immobilized on mesoporous silica particles to form a biocatalyst. Successful and promising tests were realized with this biocatalyst in various reactors designed for the micro pollutants abatement process.
