Authors:Ifeoluwa Victoria Olaogun, Deke Victoria Adegunloye Abstract: This research explored the potential of corn stover and rice bran as suitable biomass for biofuel production through microbial investigation, proximate analysis and evaluation of mineral content using conventional techniques. The microbial investigation revealed twenty microorganisms in total. Generally, the most predominant bacteria found in both samples were from the genus Bacillus, followed by Paenibacillus. The predominant fungi were from the genus Aspergillus. The total bacterial and fungal count for corn stover was 4.56 x 105 cfu/g and 2.55 x 105 sfu/g, while it was 5.97 x 105 cfu/g and 1.36 x 105 sfu/g for rice bran. The results obtained from the proximate and mineral evaluation showed that both corn stover and rice bran had a low moisture content (6.06%, 5.47%) and ash content (5.23%, 5.18%) which can boost the efficiency of the fuel produced. Corn stover had a crude fibre of 38.09%, crude fat of 1.87%, and crude protein of 3.56% while rice bran had a crude fibre of 29.72%, crude fat of 1.21%, and crude protein of 3.25%. They both had high carbohydrate contents with corn stover having 51.44% and rice bran having 57.89% which can liberate suitable amounts of monomeric sugars for the production of biofuels. Both samples had a moderate mineral content and a comparative study showed that corn stover had a higher potassium (31.51%), phosphorus (23.26%) and magnesium content (14.87%) while rice bran had a higher calcium (32.24%) and iron content (5.79%). Due to their composition and nutritional content, corn stover and rice bran can serve as suitable subtrates and present an economically viable solution for the production of biofuels. Employing them as energy sources will not only eradicate wastes but also create wealth without affecting the food supply.

Abstract: Purpose: This paper aims to establish the effects of electricity transmission lines on the livelihoods of communities in Ghana. Method/ Approach: The paper adopts the stakeholder theory framework with quantitative research techniques to explained and established the effect of electricity transmission lines on community livelihoods. Findings: The findings revealed that, electricity transmission projects have a substantial effect on communities such as access to farmlands. It also emerged that communities perceived such projects as a threat to their health and livelihood. Originality: Contextually and geographically, paper is the first of its kind and has not been published anywhere. Limitations: The limitation of the paper lies in its methodological approach where a qualitative research technique could have unearthern the perceptions variables of community dwellers Recommendation: It is recommended that an effective and broader community education and stakeholder must be done prior to the implementation any electricity transmission line projects. The use of other data collection and sampling techniques to enable the transferability and generalization of the findings is recommended. Conclusion: The study concluded that electricity transmission projects do provide benefits for the communities within the catchment areas, despite the negative perceptions held by residence of such communities.
