“…The result in Table 4 showed that immediately after charging, total viable count of the three experimental wastes ranged from 2.42×10 8 to 3.82×10 7 cfu/ml and a total of eight morphologically and physiologically different bacteria species (Aspergillus nigar, Bacillus spp., Escherichia coli, Klebsiella, Salmonella, lactobacillus, Pseudomonas, Staphylococcus and Streptococcus) and two fungi species (Aspergillus spp and Sacchromyces) were also isolated. This might be attributed to the nature of the substrate (Ali Shah et al, 2014;Idire et al, 2016). Immediately biogas production started, the total viable count increased significantly (p<0.05) while the isolated microorganisms reduced to six bacteria species.…”

The anaerobic states of the modified bio-digester and potentials of the generated biogas in cooking foods were evaluated. The study adopted experimental design. Data generated were analyzed using one-way analysis of variance and independent t-test. Carbon, free fatty acid, chemical and biochemical oxygen demand decreased significantly (p<0.05) while moisture and protein contents of the wastes increased significantly (p<0.05) after digestion. The 50% cow dung and 50% yam peel, and 50% cow dung and 50% vegetable had significantly (p<0.05) higher total (12.48%) and volatile (8.10%) solid contents respectively before digestion, but decreased significantly (p<0.05) after digestion. The pH of fermenting slurry was changing in line with the condition within the digester. Bacillus spp., Escherichia coli, klebsiella, Salmonella, Staphylococcus and Streptococcus were predominant microorganisms in all stages of biogas production from different wastes. Biogas generated from the wastes cooked significantly (p<0.05) faster than kerosene but not faster than liquefied petroleum gas. Cooking with biogas did not have any significant (p>0.05) effect on the proximate and sensory characteristics of foods when compared with the foods cooked with liquefied natural gas and kerosene.

“…Biogas research in Nigeria is in its infancy as limited substrates have been utilized and significant effort has not been directed at evaluating the composition and/or succession of the microbes responsible for the bioconversions [41]. As seen in excreta, agricultural residues and kitchen wastes as feedstock substrates [41][42][43][44][45][46][47][48][49]. The use of succulent plants for biogas production has been limited to water lettuce, water hyacinth, cassava leaves, Cymbopogon citratus and Eupatorium odoratum [41-44, 50, 51].…”

The quest for renewable and sustainable energy generation is fast becoming widespread across Africa due to the understanding that there is a need to seek an alternative to fuels of fossil origin, which currently sustains the largest portion of the world's energy need. Research into the generation of renewable fuels had been on-going in continents like Europe, South America, Asia, and other developed countries bearing in mind the extinction nature of fossil fuels. Globally, attentions are being drawn to fuel generation from biomass and its derivatives such as lignin, triglycerides, cellulose, and hemicelluloses. The aim is to use such fuels for cooking and heating and in vehicles, jet engines, and other applications. Therefore, the integration of the African continent in the race for biofuel production is germane in the quest for survival and developments considering favorable factors like climate, soil, and land mass among other environmental-friendly resources in different African countries.

Biomass gasification mainly involves a process whereby agricultural residues or biomass are subjected to partial combustion for the biomass to undergo pyrolysis and reduction, thereby releasing its gaseous component such as hydrogen, carbon-dioxide and methane. Past studies have laid emphasis on the need to study the effect of moisture content and biomass types on the rate of gasification and gasifier efficiency. This study focused on the development of a downdraft gasifier for production of syngas using agricultural wastes as raw materials. The design of the Imbert type downdraft gasifier was based on specific gasification rate, called hearth load Gh, nozzle air blast velocities, throat inclination angle, air inlet diameter and size of reduction zone. The developed gasifier consisted of a reactor, cyclone and filtration unit of 0.006, 0.016, and 0.006 m3 capacities respectively. The testing and evaluation of the designed gasifier showed adequate capacity for biomass treatment by pyrolysis. The fabricated gasifier also showed high efficiency in the pyrolysis of the selected biomasses and the product yields are appreciable. The development and use of such gasifier especially for the treatment of other agricultural wastes is hereby solicited.
