Abstract
An amino acid (L-lysine) was screened against eighteen strains ofCyanophyceae, Bacillariophyceae and Chlorophyceae. OnlyMicrocystis strains (Cyanophyceae) were sensitive tolysine; other strains were not affected. Cells of sevenMicrocystis strains (106 cellsmL−1) were completely killed within 48h by lysine at concentrations between 0.6 and 5.0 mgL−1. Two Microcystis strains wereinhibited by 92 and 98 %. Similar results were obtained when lysine malonateandlysine copper were used as algicides. Microcystis specieswere killed by lysine malonate at concentrations between 0.6 and 5 mgL−1, and by lysine copper at concentrations between 0.5and 20 mg L−1.
