title: [Antibacterial activity of pure cultures of cyanobacteria and algae].
abstract: Pure cultures of Microcystis aeruginosa, Platymonas viridis and Nephrochloris salina have been grown on the media with different nitrogen and phosphorus content. Their supernatants and pellets, as well as lipid complex, terpene fraction and some its components from M. aeruginosa had selective antibacterial characteristics. The increase of nitrogen content in the medium correlated with the intensification (M. aeruginosa, N. salina) or conservation (P. viridis) of bactericidal activity. The pellet fraction was more active than supernatant (P. viridis) one. The specific cyanobacterial and microalgal inhibitory effect is supposed with respect to the organisms of different evolutionary level.
