Microalgae grown on wastewater are promising feedstocks for biomethane production by anaerobic digestion. However, the hemicellulose composition of the microalgae cell wall inhibits hydrolysis of intracellular substances and limits their anaerobic digestibility. This study investigated enhancement of biomethane production rates during anaerobic digestion of Chlorella sp. using thermal pretreatment at varying temperatures. Experimental data were fitted to three simplified kinetic models and an energy analysis was performed to gain insights into this potential application of thermal pretreatment.
