Areas of Application
Ethanol is a promising renewable liquid fuel
used as a gasoline additive to reduce
the content of toxic substances in exhaust gas
and to prevent emission of additional carbon
dioxide to atmosphere due to the use
of renewable vegetable raw material
(lignocellulose)
Specifi cation
Ogataea (Hansenula) polymorpha recombinant
strains with a 25 times higher yield of ethanol
from xylose, an optimized medium composition,
and conditions of their cultivation are
a framework for obtaining effective producers
of ethanol from lignocellulose hydrolysates with
a maximum yield of target product
Advantages
O. polymorpha yeast recombinant strains
are more thermotolerant as compared with
the known counterparts. Due to a high ethanol
yield in the course of high-temperature xylose
alcohol fermentation the obtained strains can be
used in simultaneous saccharization and
fermentation of lignocellulose
Stage of Development.
Suggestions for Commercialization
IRL3, TRL3
Recombinant strains with increased yield
of ethanol from xylose, which have been tested
on real hydrolysites of vegetable raw materials
are provided
