About the Cover

An increase in energy consumption is projected as a result of the world's unending population growth. As a result, many are likely to rely heavily on fossil fuels. Biogas is a viable choice because it is a green fuel and also sustainable. In this study, cow manure (CM) and food waste (FW) consisting of yam and plantain peels were collected, digested, and co-digested in the following proportions: 15%:85%, 25%:75%, and 35%:65%. Five (5) AD reactors of the same capacity (25 liters) were used to digest and co-digest CM and FW. The experiment was designed to discover the best proportion variation of CM to FW that will yield the greatest results. The results reveal that digestion of FW without seeding with CM takes a lengthy time to complete. In addition, co-digestion of FW with CM serving as a seeding agent took a shorter time. It was discovered that the percentage variation of co-digestion of CM (25%) to FW (75%), as opposed to the percentage variation of co-digestion of CM (15%) to FW (85%) and the percentage variation of co-digestion of CM (35%) to FW (65%), resulted in the highest biogas yield.

Comparative metagenomic analysis of rhizosphere soil associated bacterial community structure and function from Zea mays and Brassica nigra

Manisha Mandal, Biswajit Ghosh, Shyamapada Mandal

Background: The rhizosphere soil is the hotspot for diverse plant-microbe interactions, which is beneficial for plant productivity. Two economically significant and Indigenous (Malda, India) crops, Zea mays, and Brassica nigra, were analyzed in this study using 16SrRNA metagenomic sequencing to explore the structure and function of rhizomicrobiome with advantageous interaction with the plants

Experimental investigation on the impact of Vinisil, Rubber Latex and Methacrylate Ester with Dimethylaminoethyl for dehydration in natural gas pipeline

Godloves NT, Alerechi UP, Onwuchekwa OV

Hydrate formation is a major issue with flow assurance in the oil and gas business. Hydrates compounds are crystalline and non-stoichiometric substances that form when gas and water are combined at high pressure and low temperature. Hydrates accumulating along flow line could cause restrictions to flow
