Abstract
The concern on how food and livestock waste should be managed and recycled has greatly increased in the world. This research investigated the anaerobic decomposition (digestion) process for biogas production on dairy cattle manure (CM) and food waste (FW) using a bacteria as inoculum - Pseudomonas aeruginosa. CM and FW were co-digested with bacteria (P. aeruginosa) as the substrate. FW was allowed to decompose separately without inoculum for 30 days. Digesters (Bioreactor) were prepared in five places to monitor the maximum biogas production, generation rate of methane and number of days for the production of biogas. 1 to ratio 5ml and 10ml of FW were co-digested with P. aeruginosa (bacteria) in 2 proportion and also Cow manure with 1 to ratio 1 and 0.5ml in 2 proportions [ 1:5ml; 1:10ml and 1:1; 1:5ml]. Batch process operation was used under mesophilic condition (35⁰C) for the digesters/bioreactor. Production of biogas was notices on the third and fourth day after commencement for the digesters with cattle manure, fourth to fifth day for the digester (bioreactor) with bacteria and third day for the digester with only FW. FW and CM generated highest cumulative biogas with volume of 88.5g/kg.
