Effect of organic loading rate on anaerobic digestion of thermally pretreated Scenedesmus sp. biomass

► Increasing the organic loading rate did not affect anaerobic digestion performance. ► Scenedesmus sp. biofuel production is hindered by its cell wall. ► Storage time of Scenedesmus sp. biomass affected organic matter hydrolysis. ► Scenedesmus sp. thermal pretreatment was beneficial for anaerobic digestion.
