blue-green (Cyanobacteria)Cyanobacteria (blue-green algae)

Cyanobacteria are photosynthetic organisms and as such require light (400–700 nm wavelength) and a supply of inorganic carbon to grow. The photosynthetic rate is also affected by nutrient level (particularly phosphorus), water temperature and water chemistry. For Microcystis , the maximum photosynthetic rate of 28.9 × 10 −6 (mol C) (mol cell C) −1 s −1 at 20°C is achieved at a photon flux of 753 × 10 −6 mol photon m 2 s −1 ( Reynolds, 1990 )....
