Industrialization progress of lignocellulosic ethanol

Lignocellulose is an abundant and renewable biomass that mainly composed of cellulose, hemicellulose lignin. The development utilization lignocellulosic ethanol effective way to solve the energy problem/crises, In addition, industry can play a significant role in controlling environmental pollution extending agricultural industrial chain; however, it has not been able realize large-scale industrialization due limitation both biotechnology economy. This review first introduces status ethanol, then focuses on progress practical technology analyzing economic feasibility second-generation bioethanol plant; finally, future trend was prospected. To summarize, continuous technological innovation needed vital steps such as pretreatment, enzymatic hydrolysis, fermentation. Meanwhile, for making cellulosic truly economically competitive, we also need achieve interdisciplinary, cross-domain integration innovation, construction raw material collection storage system, situ producing special enzyme high-value components, developing closely refinery with mature equipment overall programs, etc. It hoped this provide useful reference bioethanol.
