(FR) BIODÉGRADATION DE PRODUITS CHIMIQUES FLUORÉS
Abstract
(EN)
Media are described herein for the degradation and/or remediation of fluorochemicals. Briefly, a medium comprises an electron donor; a fluorochemical component; an electron acceptor; and a Feammox bacterium and/or one or more enzymes exhibiting reductive dehalogenase activity, the Feammox bacterium and/or enzyme(s) capable of fluorochemical degradation in conjunction with oxidation of electron donor and electron transfer to the electron acceptor. In some embodiments, the fluorochemical component comprises one or more fluorochemicals selected from the group consisting of perfluoroalkyl compounds, polyfluoroalkyl compounds, fluorinated carboxylic acids, fluorinated alcohols, and fluorinated sulfonates. The medium, in some embodiments, comprises water, soil, sludge, sorbents and/or solids contaminated with the fluorochemical component.

L'invention concerne des milieux pour la dégradation et/ou la remédiation de produits chimiques fluorés. En bref, un milieu comprend un donneur d'électrons; un composant fluorochimique; un accepteur d'électrons; et une bactérie Feammox et/ou une ou plusieurs enzymes présentant une activité de déshalogénase réductrice, la bactérie Feammox et/ou la ou les enzymes étant capables d'une dégradation fluorochimique conjointement avec l'oxydation d'un donneur d'électrons et d'un transfert d'électrons vers l'accepteur d'électrons. Dans certains modes de réalisation, le composant fluorochimique comprend un ou plusieurs produits chimiques fluorés choisis dans le groupe constitué par les composés perfluoroalkyle, les composés polyfluoroalkyle, les acides carboxyliques fluorés, les alcools fluorés et les sulfonates fluorés. Dans certains modes de réalisation, le milieu comprend de l'eau, du sol, des boues, des sorbants et/ou des solides contaminés par le composant fluorochimique.
