On regularities of copper bio-accumulation by representatives of autotrophic and heterotrophic organisms

The technique of inversion voltammetry aimed at the definition of the amount and content of copper in live organisms is improved. It was established that the longer was the exposition of cyanobacteriae culture to copper sulfate solution the bigger was the amount of copper concentrated on the cells’ surface. A practically total extraction of copper ions from the solution within 14 days demonstrated that the culture can be used for the new biosorbent development. It was revealed that with the increase of glutathione consentration in solution the accumulation of ions of heavy metals increases as well, and it decreases with the presence of water fleas. This in turn affects the results of biotesting solutions with the identical content of copper but various content of glutathione. The solutions with the minimum content of glutathione are acute toxic to water fleas and solutions with the maximum content are toxic to cyanobacteriae. It indicates that organisms of various systematic accessory can react differently in the presence of toxicants.
