Abstract: Biorefinery technologies using lignocellulosic biomass as feedstock have become a hot topic and huge task in globle research and development，which are also an important goal of long\|term biomass energy roadmap in both EU countries and the United States. However，the current overall level is still in pilot stage. China has abundant biomass resources，which has great potential in the production of biomass energy and bio\|based chemicals，but also faces a lot of bottleneck problems to be solved in order to achieve commercial production. The lack of efficient fermentation strains simultaneously ferment cellulosic hydrolyzate，has become a key constraint in cellulosic biorefinery. Currently，Zymomonas mobilis has became a preferred host in cellulosic ethanol fermentation for its unique ED pathway. Z. mobilis also showed some advantages of higher specific rate of sugar uptake，etc.，which made it an ideal platform for commercial\|scale production of desirable bio\|products，such as sorbitol，gluconic acid，succinic acid and isobutanol. This paper reviewed the research history，molecular biology，strain improvement and its application in biorefinery system, and also put forwards that Z. mobilis could be considered as a noval important microbe platform of cellulosic biomass biorefinery system.
