| Abstract: | Pseudomonas sp. strain IST103 obtained from a stable consortium was capable of degrading pentachlorophenol (PCP) as sole carbon and energy source. The PCP-degrading potentiality of the strain was determined by growth of bacteria in culture medium, utilization of PCP by high performance liquid chromatography (HPLC), chloride release and ring cleavage. The strain was applied in two set of soil microcosms containing 20 and 40% moisture, each having different concentrations, 0, 10, 100, 500, and 1000 mg/l, of PCP. The result showed significant utilization of PCP (77% in 45 days) and higher growth of bacterial strain when PCP was applied in 100 mg/l concentration at 40% moisture. Inhibitory effects on the growth of bacterial strain were seen in 500 and 1000 mg/l concentration. |
