Potential for anaerobic digestion by incubation and anaerobic fermentation of landfill waste: A case of the city of Lomé (Togo)

The objective of this work is to determine the methanogenic potential of landfill waste. To do this, two types of tests were carried out. The first one is the pre-test of anaerobic digestion by incubation carried out in a 500 mL flask in which 50 g of waste is placed in contact with 350 mL of water and the second one is the pre-test of the anaerobic digestion by fermentation also carried out under the same conditions as...

Histological and cytotoxic evaluation of Carica papaya seed oil and its potential biodiesel feedstock

Carica papaya is a fruit known for its great economic values in tropical Africa due to its diverse industrial, medicinal and nutritional benefits. In this study, oil was extracted from dried powdered C. papaya seeds using n-hexane as extraction solvent. The physiochemical characterization of C. papaya seed oil extract was investigated using AOAC standard procedures. Acute toxicity test was carried out to determine the...
