The efficiency of ethanol production will be increased by preventing poisoning of enzymes by reaction products as in current technology. Enzymes will be robustly attached to porous surfaces so that a high efficiency continuous flow process can be used. A novel selective membrane for the continuous removal of ethanol will be developed, allowing water to be saved and unreacted inputs to be recycled. The ultimate outcome will be a process which achieves dramatic water saving and greatly reduced environmental impact. In the final stage of the project we will apply our methods to the processing of cellulose from agricultural and forestry waste, with the potential of preventing the diversion of food resources into the transport fuel industry.

通过防止如现有技术中的反应产物对酶的毒害，将提高乙醇生产的效率。酶将牢固地附着在多孔表面上，使得可以使用高效连续流动过程。将开发一种用于连续去除乙醇的新型选择性膜，从而节省水并回收未反应的投入。最终的结果将是一个实现显着节水和大大减少环境影响的过程。在该项目的最后阶段，我们将把我们的方法应用于从农业和林业废物中加工纤维素，并有可能防止粮食资源转移到运输燃料行业。
