Virtually all countries, especially the developing nations, are being confronted with the twin problems of waste management and energy deficit. This development has led to the search for renewable energy sources. Biomass such as pig dung (PD), water hyacinth (WH) and maize cob (MC) are potential feedstocks for anaerobic digestion in Nigeria, however studies utilising their mixtures have not been fully explored. This study was therefore designed to evaluate the biogas yield and microbial species from mixtures of biomass feedstocks. Feedstocks utilized for this study comprised PD, WH, MC, PD:MC (1:1), PD:WH (1:1), and PD:MC:WH (1:1:1). Biogas digester was fabricated from 10 litres keg for feedstock biodegradation. Ratio 1:11 (w/v) slurry was prepared from each feedstock sample to be digested and fed into the corresponding digester, kept for 35 days for anaerobic digestion while samples of the effluent were taken at seven days interval for five weeks for laboratory analyses of their physicochemical and microbial characteristics. Gas generated was estimated based on Archimedes’ Principle. Data were analyzed using descriptive statistics and ANOVA at p ˂ 0.05.
