Digestion performance at different temperatures. The displayed volume of the gas has been normalized at standard temperature (273 K) and pressure (101325 Pa). a Daily CH4 production during 27 days of anaerobic fermentation at different temperature. b Total biogas production in 27 days (L kg−1 VS) and average CH4 production (L kg−1VS day−1) from initial period to peak period; TBP total biogas production in 27 days, ACP average CH4 production from initial period to peak period. All the data are presented as means ± standard deviations (n = 3)
