Abstract: Results show that the cellular microcystin content of Microcystis strain PCC 7806 varies between 34.5 and 81.4 fg per cell, which is positively correlated with growth rate under photosynthetically active radiation-limited growth. Data indicate a positive effect of light on microcystin production during and up to the maximum growth rate with hihger irradiances causing inhibition.
