Kinetic modeling of photoautotropic growth and neutral lipid accumulation in terms of ammonium concentration in Chlamydomonas reinhardtii

▸ Nitrogen depletion increases lipid production and limits growth effect. ▸ Neutral lipid production rate is indirectly related to biomass growth. ▸ Model equations satisfactorily predict cell growth and lipid production. ▸ Growing algae in different nitrogen concentrations is beneficial for scale up.
