title: Metabolism of Halophenols by 2,4,5-trichlorophenoxyacetic acid-degrading Pseudomonas cepacia.
abstract: Resting cells of 2,4,5-trichlorophenoxyacetic acid-grown Pseudomonas cepacia AC1100 were able to completely and rapidly dechlorinate several chlorine-substituted phenols, including 2,4,5-trichlorophenol, 2,3,4,6-tetrachlorophenol, and pentachlorophenol. Several other trichlorophenols were only partially dechlorinated. The evidence suggests that 2,4,5-trichlorophenol is an intermediate in the degradation of 2,4,5-trichlorophenoxyacetic acid by strain AC1100. Moreover, although strain AC1100 was isolated by selection for growth on a chlorinated aromatic compound, brominated and fluorinated analogs were efficiently dehalogenated by strain AC1100 resting cells, whereas an iodinated analog was poorly dehalogenated.
