Effects of hydrogen peroxide on Compsopogon caeruleus (Rhodophycophyta) and two superior plants.

Abstract

Hydrogen peroxide was investigated as a potential algaecide for the filamentous epiphytic alga, Compsopogon caeruleus (Balbis ex C.Agardh). The goal was to determine if hydrogen peroxide could be used to eliminate C. caeruleus, without affecting two other aquatic plants, Ceratopteris thalictroides, and Hygrophila rosanervis. A zebrafish (Danio rerio) was also exposed during the treatment, to observe the effects of hydrogen peroxide on fish. Concentrations between 1mM and 6 mM were tested for their ability to induce bleaching or tissue disintegration in plant and algal tissues. 1 mM hydrogen peroxide had no major effect on the alga, or on the plants. The 3 mM solution induced partial bleaching in C. thalictroides and damaged significantly de filamentous alga. The 6 mM solution killed completely the alga and damaged significantly the C. thalictroides. H. rosanervis suffered minor lesions during the treatment. D. rerio wasn’t affected by the mentioned concentrations of hydrogen peroxide.
