L-Arabinose Fermenting Yeast

NREL (Inventor)

Research output: Patent


An L-arabinose utilizing yeast strain is provided for the production of ethanol by introducing and expressing bacterial araA, araB and araD genes. L-arabinose transporters are also introduced into the yeast to enhance the uptake of arabinose. The yeast carries additional genomic mutations enabling it to consume L-arabinose, even as the only carbon source, and to produce ethanol. Methods ofproducing ethanol include utilizing these modified yeast strains.
