Secondary Metabolites of Pleustophytes as Markers of Resistance to Metal Nanoparticles

摘要

The effect of mixture of the metals' (Mn, Cu, Zn, Ag) colloidal nanoparticles of on the content of terpenoids, phenolic compounds, chlorophylls and caroten-oids in three species of pleustophytes (Limnobium laevigatum (Humb. Bonpl. ex Willd.)), Pistia stratiotes L. and Salvinia natans (L.) All.), selected as potential phytoremediators of the aquatic environment was studied. The phenolic compounds and terpenoids content significantly (by 26 and 25) decreased only in L. laevigatum, and the content of carotenoids and chlorophyll decreased only in S. natans (by 31 and 52), indicating different metabolic pathways over the reparation processes. Resistance in terms of all considered indicators was found only in P. stratiotes, so it can be recommended as a remediator regarding colloidal solutions of metal nanoparticles.
