Abstract

Cyanobacteria are photo-autotrophic organisms which can regulate their buoyancy. Cyclic exposure of solar radiation affects photo-chemical processes within the cell and this, in turn, changes the physical parameters of the organisms. The loss of the spatial stability of the mature cyanobacterial population, due to the influence of environmental changes cause surface scum in fresnwater reservoirs. Sets of equations are used to describe physical, biological and chemical properties of the dynamical behaviour of a population of cyanobacteria in an eutrophical lake.
