INCREASED ETHANOL PRODUCTION FROM XYLOSE

摘要

Methods and compositions for the production of ethanol from lignocellulosic starting materials are provided herein. Embodiments of the invention provide methods of manipulating the carbon flux of a host cell transformed with plasmids of the invention. Plasmids of the invention may include nucleotides that encode pyruvate decarboxylase. In one embodiment, a strain of the thermotolerant yeast Hansenula polymorpha that has been transformed with plasmids and polynucleotides of the invention is provided.
