Abstract:
... Massive use of glyphosate-based herbicides in agricultural activities has led to the appearance of this herbicide in freshwater systems, which represents a potential threat to these systems and their communities. These herbicides can affect autotrophic and heterotrophic picoplankton abundance. However, little is known about glyphosate impact on the whole structure of these assemblages. Herein, we ...

Abstract:
... The concept of stereoisomerism in the biological activity of compounds in living systems emerged in 1948 with the work of Louis Pasteur, who first observed the optical activity of tartaric acid. Enantiomers can produce undesired effects on biological system, due to their different optical activity, even though they possess the same physico-chemical properties in an achiral environment. For this re ...
