Abstract
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.
