Abstract

Preliminary experiment on the possibility of biogas production from guinea corn and rice husks. The two samples (guinea corn and rice husk) were collected from a farm land in Rabah Local Government Area Sokoto, Nigeria. The guinea corn husks were dried and grounded using wooden pestle and mortar. The experimental set up was carried out by measuring 75g each of their pure form and mixture with label A, B, C and D before diluting with water in a ratio of 6:1, 3:1, 1:8 and 1:1 respectively and 10kg of freshly collected rumen content was added to each sample. The total volume of biogas was determined, moisture content, ash content, fiber content and N. P. K values were determined for digested and undigested slurries, as well as bacteriafrom anaerobic and aerobic culture were isolated from the digested slurries. Results indicated that both guinea corn and rice husk produced 1000cm3and 100cm3 of biogas respectively for the period of 28 days with guinea corn having the highest biogas production, the digested slurries were rich in both mineral and nutrient contents and also some methanogenic bacteria andbacteria species identified are P. aeroginosa (11%), Bacillus spp (34%), Staphylococcus spp (16%), Enterococcus spp (9%), Vibrio cholerae (11%) Enterobacter spp (5)Salmonella spp (5%), Morganiella morganii (5%), Lactococcus lactis (2%) and Serratia marcenscens (2%). Guinea corn and rice husk can be used to produce significant amount of biogas, and digested substrates (slurries)can also be used as biofertilizers. Key words: Biogas Production, Bacteriology, Microbial Load, Proximate Analysis, Guinea Corn Husk, Rice Husk, Methanogenic Bacteria.
