Project description:Immobilization processes observed in natural soil are of a great environmental importance as they may lead to a considerable reduction in the bioavailability and, as a result, of a toxicity of xenobiotics, e.g. pesticides or their degradation products and to facilitation of biodegradation after a subsequent release of the bound chlorophenols by activity of microorganisms and decrease of pH (acid rains).In this way survival and degradation ability of the indigenous bacterial consortium or bioaugmented bacteria will not be influenced by initial high and toxic concentration of chlorophenols. The project has an ambition to bring new knowledge regarding the binding of organic contaminants of the chlorophenol series on organo-mineral complex performed by binding of humic acids on zeolite and to compare sorption abilities of humic acids isolated from different sources (lignite and oxyhumolite) for detoxification purposes in contaminated soil. Also the effect of humic acids on possible improvement of biodegradation and their potential protective effect on microbial cells will be studied.
