Abstract

In the last decade, bioethanol has become a powerful biofuel for the improvement of environmental pollution such as reduction in greenhouse gas levels. Yet, the source and type of substrate material plays a crucial role in the bioethanol production process due to the different compositional characteristics and availability of monomeric sugars. Different substrates of first, second and third generation fuel sources exist and may be used as reliable and sustainable substrates for bioethanol generation. The current review provides an overview of Vitellaria fruit pulp; its composition and characteristics for ethanol production. This study has examined literature on the background of the Vitellaria paradoxa, the characteristics and the potential of the shea nut pulp for fermentation to bioethanol. This review will be useful in harnessing the potentials of the shea pulp as industrially relevant substrate for use independently or in combination with other substrates in microbial fermentation processes for ethanol production.

Key words: Vitellaria, shea nut pulp, fermentation, composition, characterization, bioethanol.
