Paper Abstract

With the increase of microalgae biomass cultivation opportunities, kinetic modeling of microalgae photosynthesis and growth has become more significant, because precise model is an enabler for creation of effective photobioreactor, prediction of process productivity and improvement of operation environment. Light is major factor, affecting the kinetics of microalgae photosynthesis. In this case, light intensity and spectral structure are the most important characters. Under lacking light conditions photosynthesis in cells decelerates, and optical density of suspension decreases. Moreover, redundant density of photonic flux causes photoinhibition in cells, what leads to reduction of optical density of microalgae suspension. This means that optimum illumination plays vital part as well as temperature, nutritional medium, and CO2 delivery.
