Influence of light on macromolecular composition of microalgae in continuous culture of low density (Part 2)
It is shown that the form of dependence of macromolecular composition of microalgae biomass on light is determined by the ratio of saturating values of photosynthesis and synthesis of structural components of cells. When processes rates are limited in the sequence of conversion of resource substances into structural ones, with no light saturation achieved, spare substances in the form of carbohydrates and possibly lipids are accumulated in the cells. The equations allowing to describe the dependence of ratio of resource (reserve) and structural forms of biomass on the light intensity in dynamically equilibrium (continuous) culture of low density are obtained.
