ABSTRACT:
This invention relates to a recombinant microorganism which expresses pyruvate decarboxylase, alcohol dehydrogenase, Klebsiella phospho-.beta.-glucosidase and Klebsiella (phosphoenolpyruvate-dependent phosphotransferase system) cellobiose-utilizing Enzyme II, wherein said phospho-.beta.-glucosidase and said (phosphoenolpyruvate-dependent phosphotransferase) cellobiose-utilizing Enzyme II are heterologous to said microorganism and wherein said microorganism is capable of utilizing both hemicellulose and cellulose, including cellobiose, in the production of ethanol.
