  reportOpen access

  Global climate change - due largely to the emission of anthropic CO2 - has been recognized by the scientific community for many decades and is becoming increasingly obvious to the public due to extremely hot summers, drought, and frequent fires. Destruction of tropical forests especially contributes to climate change and loss of species diversity.

• Disruption of the cytochrome C gene in xylose-fermenting yeast

  OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023-01-23

  articleOpen access1st authorCorresponding

  Disclosed is a xylose-fermenting mutant yeast strain exhibiting reduced expression of cytochrome c and enhanced fermentation of xylose relative to xylose-fermenting yeast strains in which cytochrome c is fully functional. Also disclosed is a method of producing ethanol from xylose by culturing a xylose-fermenting mutant yeast strain exhibiting reduced expression of cytochrome c in the presence of xylose-containing material.

• Co-fermentation of glucose, xylose and/or cellobiose by yeast

  OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023-01-23

  articleOpen access1st authorCorresponding

  Provided herein are methods of using yeast cells to produce ethanol by contacting a mixture comprising xylose with a Spathaspora yeast cell under conditions suitable to allow the yeast to ferment at least a portion of the xylose to ethanol. The methods allow for efficient ethanol production from hydrolysates derived from lignocellulosic material and sugar mixtures including at least xylose and glucose or xylose, glucose and cellobiose.
