Abstract
The work presents the result of some tests on the action of phenol
and beta-indolil acetic acid on a few unicellular algae, common in
the Black Sea phytoplankton. The tested products change the membrane
permeability for the trophic substratum, which causes modification
in the rate of utilization of the medium and implicitely the 
variation of the generating time and of biomass of the studied algae.
