Influence of light on microalgae growth in continuous culture of low density

Abstract

A mathematical model of the dependence of the specific growth rate of microalgae on the light intensity for a continuous culture of low optical density is proposed. In the basis of the mechanism of light-limited growth is the thesis on photosynthesis having light and dark phases. The product of the first phase is carbohydrates, which are used in the dark phase as a source of energy and carbon skeletons for the synthesis of all structural components of cells .Rates of the processes are described by linear splines. The equations describing the dependence of the specific growth rate on the intensity of the acting light are obtained.
