Abstract
Microtox™ bioassay was used for assessing the complexation of copper with organic compounds including humic acids and corn root exudates. The bioassay, based on reduction of bacterial luminescence in the presence of toxicants, consists of determining the toxicity of organo-metallic complexes and thus assessing the bioavailability of copper to the test bacteria. Natural organic compounds reduced the extent of copper toxicity. Thus, Microtox can be used as a rapid tool for assessing the interactions of heavy metals with organic ligands.
