title: Dechlorination of PCB in the presence of plant nitrate reductase.
abstract: The dechlorination of PCB, specifically the noncoplanar congener PCB 153, has been observed in the presence of a crude nitrate reductase extract from Medicago sativa leaves. These observations were further confirmed using a commercially available and pure nitrate reductase from Zea mays. The presence of nitrate reductase increased PCB 153 dechlorination. Then, the addition of molybdenum, the enzyme's cofactor, enhanced dechlorination of the environmental contaminant. The ability of plant nitrate reductase to dechlorinate PCB is a new observation.
