Features of self-organization and biological properties of solutions of citric and succinic acids in low concentrations

Resumo

A relationship between the nonmonotonic concentration dependences of the size of the dispersed phase (nanoassociates), physicochemical properties (electric conductivity, pH, redox potential), and fertility of hydrobionts under the action of solutions of citric (CA) and succinic (SA) acids in low concentrations was established. Solutions of CA stimulate the fertility of Paramecium caudatum infusoria and Chlorella vulgaris algae in a wide range of formation of domains and nanoassociates (1•10^–13–1•10^–5 mol L^–1), whereas solutions of SA exert almost no effect on the fertility and slightly inhibit it only in a range of nanoassociate formation at the calculated concentrations from 1•10^–17 to 1•10^–14 mol L^–1.
