Abstract

We provide a system of differential equations to model nitrogen consumption of a unicellular green microalgae and their growth. The model was modified to account different mechanisms of unionized ammonia and ammonium ion, up taken by unicellular green microalgae. An agreement between the theoretical mathematical model and experimental measure-ments was studied in order to validate the model. Parameter optimizations were performed by using a genetic algorithm.
