Abstract

The invention utilizes cloning and transformation techniques in combination with mutation and strain taming techniques to obtain yeasts having high xylose consumption rate and ethanol yield. The cloning and transformation used in the invention are to transform xylose metabolism genes to yeasts to solve the problem that some yeast strains cannot utilize xylose to produce ethanol. The mutation and strain taming used in the invention are to increase xylose consumption rate and ethanol yield to solve the problem of low rate and yield. By combining the above-mentioned technical means, the invention unexpectedly obtain a mutant having high xylose consumption rate and ethanol yield.
