Determination of Yield Coefficients of Methane and Carbon Dioxide in Methanogenesis to Predict the Overall Performance of a Biogas Digester
Biogas has globally remained a renewable energy source derived from anaerobic digestion of organic matter. This process treats the organic matter efficiently producing a effluent whose residue is rich in inorganic elements like nitrogen and phosphorous needed for effective plant growth. In our investigation determination of yield coefficients of methane and carbon dioxide in methanogenesis was done considering volatile fatty acid and long chain fatty acids as the principal substrates obtained after the acidogenic degradation of vegetable market waste. The purpose of considering these two substrates is that these are the primary substrates for the methanogens needed to produce biogas. Besides, a pure chemical source of volatile fatty acid and long chain fatty acids has been used to conveniently determine yield coefficients of the products of methanogenesis which matched well with the biogas generated from the digester.
