Research progress on bioethanol production with microalgae as feedstocks.

Fuel ethanol as excellent renewable liquid fuel,has received widespread attention for its exceptional performance. Microalgae is one of the best biomass resources with high photosynthetic efficiency and high biomass yield. Microalgae rich in starch,polysaccharides,cellulose(Iα) and other substances can be used as excellent feedstock for fuel ethanol production with traditional ethanol production technology after simple treatment. Fuel ethanol production with microalgae can alleviate China's growing energy problems,and reduce greenhouse gas emissions and environmental pollution. The recent research progress on microalgae ethanol reviewed and proposed its developmental potential.
