Aquatic ecosystem as a bioreactor: water purification and some other functions

A detailed analysis of the discovery and innovation: a new aspect of the functioning of ecosystem was discovered and analyzed. The paper showed that ecosystem has attributes of a bioreactor. It is considered as a large-scale diversified bioreactor with a water self-purification function.

Abstract:

A fundamental concept is proposed of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams. The ecosystem as a bioreactor has the following characteristic attributes: (1) it is a large-scale (large-volume) bioreactor; (2) it is a diversified (in terms of the number of taxa and the scope of functional activities) bioreactor; (3) it possesses a broad range of biocatalytic (chemical-transforming and degrading) capabilities. New experimental data on xenobiotics-induced inhibition of the functioning of the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and Limnaea stagnalis emphasize the potential ecological hazard from sublethal concentrations of pollutants (including those exemplified by synthetic surfactants and detergents).
