ABSTRACT:
Enzymatic dehalogenation of undesirable nitrogen-free organohalogen compounds is carried out by adding bacteria 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 NCIMB 40271, 40272, 40273 and 40274 were deposited on Apr. 2, 1990. NCIMB 40313 was deposited on Aug. 31, 1990 and NCIMB 40383 was deposited on Mar. 11, 1991.
