Resea.ch works in the recent pa.t ha.e revea.ed three ma.or biodegra.a.ion processes lea.ing to the degra.a.ion of trichloroethylene. Reductive dechlorina.ion is a. a.a.robic process in which chlorina.ed ethenes a.e used a. electron a.ceptors. On the other ha.d, cometa.olism requires oxygen for enzyma.ic degra.a.ion of chlorina.ed ethenes, which however yields no benefit for the ba.teria.involved. The third process is direct oxida.ion under a.robic conditions whereby chlorina.ed ethenes a.e directly used a. electron donors by microorga.isms. This review presented the current resea.ch trend in understa.ding biodegra.a.ion mecha.isms with rega.d to their field a.plica.ions. a.l the techniques used a.e eva.ua.ed, with the focus being on va.ious fa.tors tha. influence the process a.d the outcome.
