Peroxidase driven micromotors for dynamic bioremediation.

Phenolics are size products present in tons concentrations in industrial wastewater that can cause adverse health effects when released in the environment. As such, there is a growing interest in the development of efficient strategies for the removal of phenolic compounds from polluted water. Herein we describe the use of poly(3,4-ethylenedioxythiophene) (PEDOT)-Au/peroxidase micromotors as dynamic biocatalytic platforms for the removal of model phenolics (phenol, bisphenol A, guaiacol, pyrogallol and catechol).

Peroxidase Immobilized Cryogels for Phenolic Compounds Removal.

In this presented work, preparation of poly(AAm) cryogel, peroxidase immobilization onto the poly(AAm) cryogel, and usability of these enzyme modified cryogels for phenolic compounds removal were described. For this purpose, poly(AAm) cryogels were synthesized by using cryocopolymerization technique at sub-zero temperatures, and covalently functionalized with peroxidase enzyme by EDC/NHS chemistry. Characterization of the cryogels was carried out by FTIR, SEM, and EDX analysis.
