2,4,5-三氯苯氧乙酸培养的洋葱假单胞菌AC1100静息细胞能够完全、快速地脱氯几种氯代苯酚，包括2,4,5-三氯酚、2,3,4,6-四氯酚和五氯酚。其他几种三氯苯酚仅部分脱氯。有证据表明，2,4,5-三氯苯酚是菌株AC1100降解2,4,5-三氯苯氧乙酸的中间体。此外，虽然菌株AC1100是通过选择在氯化芳香族化合物上生长而分离出来的，但菌株AC1100静息细胞对溴化和氟化类似物的脱卤效果很好，而对碘化类似物的脱卤效果很差。
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.
