The effects of light, temperature, nitrogen and phosphore on inhibitory metabolites (toxins) production and growth of Fischerella muscicola were studied under laboratory conditions. A factorial experiment with a split plot design was used to quantify the interaction of environmental factors and inhibitory metabolites production. Results indicated that the physical factors, i.e., light and temperature, affected the toxicity of the cyanobacterium at a statistically significant level (
