Zymomonas mobilis Can be useful as bioenergy with high ethanol tolerance, high ethanol conversion, and high ethanol production. The influencing factors were studied about Two-dimensional gel electrophoresis technology on Zymomonas mobile, and the optimized conditions for 2-DE map were established. The result showed good repeatability and high resolution. This technology built the foundation of comparative proteomic analysis and clonging of the high ethanol producing ratio gene.
