ZYMOMONAS WITH IMPROVED ARABINOSE UTILIZATION

摘要

Several strains of arabinose-utilizing Zymomonas were engineered to express an arabinose-proton symporter which was found to provide the strains with improved ability to utilize arabinose. These strains have improved ethanol production in media containing arabinose, either as the sole carbon source or as one sugar in a mixture of sugars.
