Title: Effect assessment of temperature on biogas production from bovine rumen and banana (Musa acuminata) stem undergoing anaerobic codigestion

In this research banana (Musa acuminata) stem waste and bovine rumen were taken to undergo degradation by anaerobic codigestion. The stem and rumen were mixed to obtain four ratios of substrate and three replicates were taken for each. 750 mL bioreactors were used, with a 3 temperature factorial arrangement (25, 35 and 45°C). Initial conditions and final physicochemical parameters were analysed. The total Chemical Oxygen Demand removal (CODr) was 13.5 and 41.8% and Volatile Solids (VS) removal only between 12.8-50.9%. The methane content in each of the bioreactors was measured by gas chromatography for 40 days. The temperature that gave the highest methane production was 45°C, followed by 35°C and 25°C, with values of 1250.1, 1018.2 and 885.7 mL, respectively. Keywords: anaerobic codigestion; methane production; banana stems; bovine rumen; greenhouse gases; GHG emissions; waste management; anaerobic digestion; temperature; biogas production; Musa acuminata; chemical oxygen demand; COD removal; volatile solids; bioreactors.
