Biobutanol Production from Lignocellulosic Biomass: Prospective and Challenges

Abstract

Biobutanol production from lignocellulosic biomass is considered promising and economically feasible. This paper provides an updated review on development of lignocellulose-based biobutanol production with a focus on the understanding of the structure of the feedstock, pretreatment technologies, and fermentation processes. To enhance butanol production from lignocellulosic materials, strategies in terms of inhibitors detoxification, strains improvement and process integration and optimization are also addressed. Besides, the reviewer attempts to shed light on the challenges and perspectives for the bioconversion of lignocellulosic biomass-to-butanol.
