Effects of Environmental Factors on Toxicity of a Cyanobacterium ( <i>Microcystis aeruginosa</i> ) under Culture Conditions

Abstract

Effects of light intensity, temperature, and nutrients on the toxicity of Microcystis aeruginosa were investigated, using a toxic strain which kills mice. A marked change in toxicity was observed in the light intensity experiment, and slight changes were observed to be caused by temperature and phosphorus deficiency.
