Construction and characterization of heavy metal-resistant haloaromatic-degrading Alcaligenes eutrophus strains
- SCK/CEN-VITO, Mol (Belgium)
The use of specialized bacterial strains that are able to degrade organic pollutants, such as polycholorinated biphenyls (PCBs) and pesticides, is becoming increasingly important for decontaminating polluted soils, sludges, and groundwaters. However, bioremediation of sites polluted with organic compounds might be impaired by the presence of heavy metals. The researchers used Alcaligenes eutrophus strains to test responses to heavy metals by evaluating their capacity to degrade organic xenobiotic compounds. The constructed strains were able to grow in the presence of nickel and zinc and exhibited unimpaired biodegradation activities. Both properties are important in considering microorganisms for decontamination of areas with organic xenobiotic and heavy metal pollution. 36 refs., 1 fig., 6 tabs.
