| Research Abstract |
An introduction method of the xylose isomerase pathway into the yeast by the genome integration of xylose isomerase encoding gene was constructed. Ethanol fermentation abilities from glucose and xylose of both only xylose isomerase pathway introduced yeast and xylitol, by-product of fermentation from xylose, pathway blocked that yeast were evaluated. And glucose and xylose consumption rates were improved by the overexpression of the transporter that intermediate uptake of the sugars into the yeast.
