Abstract:
The purpose of this study is to determine the rate of biogas production from cattle dung and cattle abdominal wastes, with a view to knowing the best for biogas yield. The two different wastes used for the work were obtained fresh from Sokoto abattoir in Sokoto State of Nigeria. The wastes were respectively collected in clean polythene bags. The apparatus used comprise of pairs of 250cm3 conical flask, two hole rubber cork, measuring cylinder, thermometer, delivery tube, trough of water, beam balance, nutrient agar, autoclave, incubator and gram staining reagents. Two conical flasks of size 250cm3 were thoroughly washed and allowed to dry in an oven at 1100C. 100/g of each organic waste was mixed with distilled water to form slurries; the flasks were labeled for distinction. The two different wastes were subjected to the same anaerobic fermentation in the laboratory and their rates of biogas production were monitored using graduated inverted cylinders. The daily production of biogas from the wastes was studied. The results show that the cattle abdominal waste produced biogas faster than the cattle dung but the cattle dung gave a higher volume of biogas than the cattle abdominal waste. Microbiological analysis of the fresh wastes using standard microbiological methods reveals that the cattle dung contains Methanococcus bacteria while the cattle abdominal waste contains Methanobacillus bacteria and Methanococcus spp. In conclusion, the study showed that cattle dung is a better organic waste for biogas production than the cattle abdominal waste.
