Dehalogenation of organohalogen-containing compounds

Abstract From the Canadian patent

Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding a dehalogenase to an aqueous composition comprising a nitrogen-free organohalogen compound and a nitrogen-containing cationic polymer. The enzymatic dehalogenation of the nitrogen-free organohalogen compound is achieved without any substantial effect upon the nitrogen-free organohalogen compound. The dehalogenation method may be carried out via continuous batch, or semi-continuous processes. The composition is especially useful as a paper wet strengthening formulation, and is useful in commercial papermaking processes. The resulting paper product comprises a residue of a microorganism. …
