A reduced dynamic model for anaerobic digestion of microalgae is developed, accounting for the uncoupling between methane production and ammonium release. Three reactions are considered: two parallel hydrolysis-acidogenesis steps for, respectively, sugars/lipids and proteins, followed by a methanogenesis step. The model accurately reproduces experimental data for anaerobic digestion of the freshwater microalgae Chlorella vulgaris. Its reduced complexity makes it suitable for developing advanced control and monitoring strategies.
