Abstract in Portuguese
Contribuição ao conhecimento da ação algicida do sulfato de cobre, em especial sobre a cianofícea Microcystis flos-aquae (Wittrock) Kirchner. O presente trabalho descreve a técnica empregada para a obtenção de culturas unialgáceas de Microcystis flos-aguae (Wittrock) Kirchner e de culturas mistas onde coexistiam vários gêneros de algas mas com predominância da referida cianofícea, simulando a situação do ambiente natural. Estas culturas foram expostas a 0,1 mg/l e 0,2 mg/l do algicida CuSO4 5H2O (sulfato de cobre pentahidratado) por períodos variáveis de tempo. A espécie Microcystis flos-aquae (Wittrock) Kirchner, quando em cultura unialgáceas, resistiu por mais tempo à ação do algicida do que quando em culturas mistas.

Abstract in English
Contribution to the knowledge on copper sulfate as an algicide, with special reference to the blue-green alga Microcystis flos-aquae (Wittrock) Kirchner. The present work describes the techniques employed in order to obtain unialgal cultures of Microcystis flos-aquae (Wittrock) Kirchner as well as mixed cultures where other genera of algae were present but Microcystis flos-aquae (Wittrock) Kirchner was by far more numerous similarly as it occurs in nature. These cultures were exposed to 0,1mp/l and 0,2mg/l CuSO4 . 5H2O Cpentahydrate copper sulfate) through variable periods. Unialgal cultures of Microcystis flos-aguae (Wittrock) Kirchnero resisted longer to the algicide than mixed ones.
