Biotechnological production of ethanol from xylose using yeast

Purpose. Ethanol is a promising renewable liquid fuel used as a gasoline additive to reduce the content of toxic compounds in the exhaust gases, and also prevents the release of additional carbon dioxide into the atmosphere through the use of renewable plant materials (lignocellulose).

Specifications. Recombinant yeast strains Ogataea (Hansenula) polymorpha with a 25-fold increase in ethanol production from xylose, as well as an optimized composition of the medium and conditions for their cultivation, are the basis for obtaining effective ethanol producers from lignocellulose hydrolysates.

Application area. Energy. It can be used in boiler power generating plants of thermal power plants, thermal power plants, light industry enterprises, oil refineries, cement plants, housing and communal services

Advantages. Recombinant yeast strains O. polymorpha are more thermotolerant than their known analogs. Due to the high production of ethanol during the high temperature alcoholic fermentation of xylose, the obtained strains can be used in the process of simultaneous saccharification and fermentation of lignocellulose.
