Abstract

The influence of growth parameters such as light intensity, light quality, light-dark cycles, temperature, pH, CO2 and O2 concentration, N and P nutrition and turbulence was determined on the growth of toxic and non-toxic axenic Microcystis isolates under laboratory conditions. The wide differences observed between laboratory and natural cultures especially with regard to light sensitivity were partially explained when laboratory cultures were grown in the presence of bacteria and when experiments were carried out under natural conditions over a long period. Equations describing the relationship between growth rate and growth parameters were deduced. These equations may be of value in predicting growth of Microcystis under natural conditions.
