The synthesis, regulation and modification of lignocellulosic biomass as a resource for biofuels and bioproducts

Abstract

Most of the plant biomass is cell wall and therefore represents a renewable carbon source that could be exploited by humans for bioenergy and bioproducts. A thorough understanding of the type of cell wall being harvested and the molecules available will be crucial in developing the most efficient conversion processes. Herein, we review the structure, function, and biosynthesis of lignocellulosic biomass, paying particular attention to the most important bioresources present in the plant cell wall: cellulose, hemicellulose, and lignin. We also provide an update on key improvements being made to lignocellulosic biomass with respect to utilization as a second-generation biofuel and as a resource for bioproducts.
