The potential for polychlorinated biphenyl biodegradation is of environmental interest because of the toxicity and bioaccumulation of these compounds. Biodegradation studies on 4-chlorobiphenyl (4CB), a model for polychlorinated biphenyl degradation, have focused mainly on the genes and enzymes that permit the degradation of 4CB to 4-chlorobenzoate (4CBA). Most biphenyl- and polychlorinated biphenyl-degrading strains accumulate the corresponding chlorobenzoic acids without degrading the chlorobenzoate to CO{sub 2}. The study demonstrated that the 4-chlorobiphenyl-degrading Alcaligenes sp. strain ALP83 can degrade 4-chlorobenzoate to 4-hydroxybenzoate. The dehalogenase activity is correlated with a 10-kb fragment carried on plasmid pSS70.
