Abstract

The microbial conversion of lignocellulosic biomass (LCB) into biofuels has become a global research hotspot for the supplementation of current energy sources. The lignocellulosic biofuel production process entails pretreatment, enzymatic hydrolysis, and microbial fermentation. Biofuel production and the microbial metabolic pathways associated with these processes are influenced by various parameters, including temperature, pH, and nutrient concentration, which could unravel key information for maximizing the process yield. This chapter provides insight into the advancement of microbial biofuel production from LCB. The current progress on bioethanol, biobutanol, biohydrogen, and biogas production processes pertaining to kinetics, microbial metabolic pathways, and key parameters are presented. Furthermore, the current challenges and future perspectives on microbial lignocellulosic biofuel production are outlined.
