Abstract

Pseudomonas veronii PH-05, a bacterial strain capable of transforming pentachlorophenol (PCP) to a metabolic intermediate, was isolated by selective enrichment of soil samples from a timber storage yard. Strain PH-05 was shown to be able to grow using PCP as the sole source of carbon and energy. GC-MS analysis showed that the metabolic intermediate was tetrachlorocatechol, which inhibited the growth of this strain. The formation of tetrachlorocatechol during biotransformation was monitored, and its inhibitory effect on growth of strain PH-05 was analyzed at a range of concentrations. The catabolic activity of the isolated strain differs from that of other PCP-degrading bacteria, which metabolize PCP through a chlorinated hydroquinone intermediate.
