Molasses is a first-generation bioethanol feedstock that is a byproduct of sugar production. Molasses is a viscous fluid; consequently, when it serves as a substrate, it needs to be dissolved in water to obtain the appropriate conditions for the yeast. Therefore, the mixing process of molasses...

Achieving an affordable clean energy in accordance to the sustainable development goal (SDG 7) is a challenge in Nigeria and other nations in Africa. Most of the currently used energy strategies are either not sustainable or poorly maintained. Nigeria is a major exporter of fossil fuel but...

Xylose, arabinose and glucose were studied their fermentabilities to ethanol by yeast Pichia stipitis. The experiments were conducted by using 1.0, 5.0, 10.0 and 20.0 g/l of mono-saccharide solutions in a close fermentation system at 30 °C with 100-rpm shaking rate for 120 h. Fermentabilities...
