Summary
Chlorophenol-mineralizing Rhodococcus strains were immobilized on modified polyurethane carrier (PUR, Bayer Ag). A column containing the immobilized bacteria was fed with technical chlorophenol (3 to 130 mg/1) contaminated water. The chlorophenol concentration of the column effluent was 1/1000–1/10,000 of the influent concentration. Inorganic chloride in effluent water and carbon dioxide in exhaust gas were found as products. The immobilized biomass adsorbed chlorophenols effectively both at room temperature and at the local ground water temperature (+4 °C). The temperature was intermittently increased to 25 °C to allow the immobilized bacteria to biodegrade the adsorbed chlorophenols. Life time of the immobilized rhodococci was several months. The degradation of chlorophenols by the immobilized cells proceeded in the absence of an additional carbon source. The method described can be applied to remove chlorophenols from ground water.
