Fermentation research in Nigeria

Socio-ecological biotechnology concepts for developing countries

“…It is encouraging to see the realization that fermented foods are mixedculture processes and that it is time to start detailed and extensive investigations into the functioning of such cultures (Doelle 1985;Steinkraus 1987;Okagbu 1988;Odunfa 1988). It is the suggestion of the author to encourage a review on mixed culture with particular emphasis on fermented food production and its waste disposal.…”

Energy analysis for onsite and offsite suburban wastewater

“…Considering the calorific power equivalent for the global warming potential of methane (CH 4 ), it is 63 compared with 1 for CO 2 over a 20-year horizon (IPCC, 2001;Prendez and Gonzalez 2008). In Nigeria, identified feedstock substrate for an economically feasible biogas production includes water lettuce, water hyacinth, dung, cassava leaves and processing waste, urban refuse, solid (including industrial) waste, agricultural residues and sewage (Okagbue 1988;Ubalua 2008;Akinbami et al 2001Akinbami et al , 1996. Harvested cassava is commonly processed into different local meals in many homes and into other useful forms (e.g.…”

Biofuel Development in Sub-Saharan Africa

“…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].…”

“…To this end, several feedstocks which are economically suitable for biogas generation in Nigeria have been selectively identified. These include aquatic plants like water lettuce and water hyacinth; agricultural wastes like cow and piggery dung, poultry droppings and processing waste; industrial wastes like municipal solid wastes and sewage [41][42][43]. Also, the continuous assessment of other locally available materials for their use in biogas production has been made [44].…”

“…The world over, several feedstock have been utilized including food wastes, animal dungs, agricultural and plant residues, wastewaters, Organic Fraction of Municipal Solid Wastes (OFMSW), energy crops, etc. Across Sub-Saharan Africa, substrates suitable for anaerobic digestion include aquatic plants such as water lettuce and water hyacinth; agricultural wastes/residues such as cow and piggery dung, Cymbopogon citratus, cassava leaves; municipal wastes such as human excreta, processing wastes, urban refuse and industrial wastes [42][43][44][45][46]. Among these, the potentials of poultry manure, cow dung and kitchen wastes for biogas production have been demonstrated [54][55][56][57][58][59].…”
