RESUMO

The influence of cationic surfactants - catamine (benzalkonium chloride) on the structural changes of the unicellular green algae Chlamydomonas reinchardtii Dang. and their physiological-biochemical indices with using an electron microscopic method were investigated. The decrease in cell number and an increase of its volume as a result of biomembrane reorganization and strengthening of their penetrability for water were established. The significant destructive changes in chloroplast membranes, in particular, the glueing of photosynthetic membranes, the widening of intramembrane space, and also the swelling of plastids, progressive cell vacuolization, and other changes of cell organelles were simultaneously registered, which frequently caused the degeneration of algae cells.
