Title: IMPROVED PROCESSES FOR PRODUCTION OF ETHANOL FROM XYLOSE-CONTAINING CELLULOSIC SUBSTRATES USING ENGINEERED YEAST STRAINS
Abstract:
Provided herein are recombinant host cells having a heterologous polynucleotide encoding a hexose transporter and a heterologous polynucleotide encoding a xylose isomerase, wherein the cells are capable of fermenting xylose in the presence of glucose and under oxygen limited growth. Also described are processes of fermenting saccharified material using the recombinant cells to produce ethanol at higher yields.
