MODIFIED BACTERIA FOR THE PRODUCTION OF BIOALCOHOL

摘要

The present invention provides a modified bacterial strain capable of fermenting both hexose and pentose sugars for production of bioalcohol wherein a promoter of pyruvate dehydrogenase operon (PDH) is replaced with a promoter of a gene that is expressed under anaerobic conditions. The present invention further provides a method of obtaining modified bacterial strain capable of fermenting both hexose and pentose sugar for production of bioalcohol. The present invention also provides a method of fermenting lignocellulosic biomass having hexose and pentose sugar using the modified bacteria for production of biomass.
