Screening microalgae strains for their productivity in methane following anaerobic digestion

► There were no significant differences in the methane potential from freshwater or marine microalgae. ► Freshwater microalgae showed higher methane production when cultured in f/2 medium compared to Bold's 3N. ► Methane production of up to 408 mL CH4/g TVS could be achieved when anaerobically digesting microalgae. ► The strain Scenedesmus sp. AMDD was chosen as a model strain for future work.
