Surfactant-promoted hydrolysis of lignocellulose for ethanol production

Abstract Although great progress has been made in the research on conversion of cellulosic ethanol, the high conversion cost still exists as an obstacle. Thus, various measures such as reducing the chemical usage, minimizing the enzyme loading, and decreasing the energy consumption are required to lower the cost. Adding surfactants in bioethanol production process is recognized as a simple, effective, and economical strategy to enhance the fermentable sugars production. Therefore, making full use of surfactants (e.g., natural saponin from agricultural and forestry wastes and lignosulfonate) and other industrial wastes in the production of cellulosic ethanol would bring significant economic and environmental benefits. In this review, the recent progress on the application of different types of surfactants (synthetic, natural, and biosurfactant) in cellulosic ethanol production was summarized. The possible mechanism by surfactants was explored. The challenges of current research and outlook of surfactants used in the bioconversion of lignocellulosic biomass were also discussed.
