IMPROVED ETHANOL PRODUCTION IN FERMENTATION OF MIXED SUGARS CONTAINING XYLOSE

摘要

Xylose-utilizing Z. mobilis strains were found to have improved ethanol p roduction when grown in medium containing mixed sugars including xylose if s orbitol or mannitol was included in the medium. The effect was seen in conce ntrations of mixed sugars where no growth lag period occurs, as well as in h igher sugars concentrations.
