The proximate composition of foods includes moisture, ash, lipids, protein and carbohydrate contents. This component may be of interest in product development, quality control, screening or regulatory purposes especially during fermentation. Methanogenesis was once considered a special type of fermentation. However, in some respect a very unique biochemistry is involved, which distinguish methanogenesis from fermentation as well as respiration. Analysis used may be rapid methods for screening and quality control or more accurate but time-consuming official methods. Sample collection must be considered carefully during this analysis to ensure analysis of a homogenous and representative sample, and to obtain accurate results. This is achieved by the breakdown of complex polymeric substances such as carbohydrate, protein, fatty acid to simple compounds like carbon dioxide (Co2), methane (CH4), hydrogen sulfide and other trace elements. The process is carried out by strict anaerobic bacteria all of which belong to the phylum Euryarchaeota. ATP synthesis during methanogenesis is based on electron transport linked phosphorylation not substrate linked phosphorylation. In view of the ever-increasing costs and the negative environmental impacts of petroleum-based fuels and enormous amount of sawdust generated yearly in Nigeria. This study was undertaken to assess the suitability of Sawdust, Cow dung and Mixed fruit and vegetable residue as source of energy by determining their chemical properties via proximate analysis carried out at the International Institute of Tropical Agriculture, Ibadan, Oyo state. The aim of this work is geared towards determining the chemical constituents of these substrates and to ascertain its usability in biomethenation, to be added to the substrate biomethane potential (BMP) database of these substrates for referral purposes in scientific findings and research. This is because optimum methanization (biogas production) is only possible with the optimum range of pH, Carbon, Nitrogen, Carbon Nitrogen ratio, ash content, sulfur and others of these factors and macro nutrients.
