Abstract

A chemostat is a widely used laboratory and industrial scale equipment for continuous culture of microalgae and other microorganisms under controlled conditions. Being a photosynthetic organism, light and other nutrients are growth limiting for all microalgal species, and thus optimization of external conditions is necessary to maximize algae harvest at a commercial scale. In this study, we mechanistically formulate a cell quota-based, light-dependent model of algae growth in a chemostat and study various mathematical properties of the model, in addition to exploration of the parameter space for obtaining guidelines on biomass growth optimization.
