Industry-ready process makes plastics chemical from plant sugars

Industry-ready process makes plastics chemical from plant sugars

May 12, 2019 |

In Wisconsin, researchers at UW–Madison and the Great Lakes Bioenergy Research Center developed an inexpensive, industry-compatible process to produce high yields of the versatile chemical HMF – 5-hydroxymethylfurfural, which is used to make many bio-based chemicals, plastics and fuels. The team’s research shows that the process is simple and compatible with the existing infrastructure in […]

More than meets the eye – Carbon efficiency isn’t the whole story for biofuels

More than meets the eye – Carbon efficiency isn’t the whole story for biofuels

October 21, 2018 |

In Wisconsin, a study from researchers at the University of Wisconsin–Madison and the Great Lakes Bioenergy Research Center compared two processes for producing biofuels from corn stover: biological conversion to ethanol (BCE) and catalytic conversion to alkenes (CCA) and found that carbon efficiency isn’t the only factor for determining promising strategies for the production of […]

Red-hued yeasts hold clues to producing better biofuels

Red-hued yeasts hold clues to producing better biofuels

October 13, 2018 |

In Wisconsin, a team based at the University of Wisconsin–Madison and the Great Lakes Bioenergy Research Center found clues in red-hued yeasts that could help harness the synthesis pathway for large-scale production of isobutanol as a biofuel. A red pigment called pulcherrimin, naturally produced by several strains of wild yeasts, is synthesized in part through […]

Pre-winter switchgrass harvest produces better ethanol yields

Pre-winter switchgrass harvest produces better ethanol yields

September 22, 2018 |

In Michigan, researchers from Michigan Technological University, University of Tennessee, University of Wisconsin-Madison and Michigan State University are looking at Wisconsin switchgrass to better understand the costs and benefits to harvesting at various points in the season. Comparing data from samples collected every two to three weeks from the switchgrass fields against biofuel yield data […]

University of Wisconsin–Madison researchers tweak yeast genes to better tolerate pretreatment

University of Wisconsin–Madison researchers tweak yeast genes to better tolerate pretreatment

August 13, 2018 |

In Wisconsin, researchers from the University of Wisconsin–Madison and several Department of Energy laboratories have identified two changes to a single gene that can make the yeast tolerate the pretreatment chemicals. They published their findings recently in the journal Genetics. The researchers used the gene-editing tool CRISPR to alter a strain of an ionic liquid-susceptible […]

Yeast can be protected from damage in biofuel production

Yeast can be protected from damage in biofuel production

August 11, 2018 |

In Wisconsin, researchers from the University of Wisconsin–Madison and several Department of Energy laboratories identified two changes to a single gene that can make yeast tolerate pretreatment chemicals during biofuel production. The toxicity involved in pretreatment chemicals is enough to make the yeast as much as 70 percent less efficient at turning sugar into biofuel, […]

University of Wisconsin-Madison and ExxonMobil extend R&D agreement two more years

University of Wisconsin-Madison and ExxonMobil extend R&D agreement two more years

July 17, 2017 |

In Wisconsin, the University of Wisconsin-Madison and ExxonMobil have announced a two-year renewal of an agreement to research the fundamental chemistry of converting biomass into transportation fuels. The research is part of a broad effort to identify scalable and commercially viable solutions to help meet increasing global energy demand with a renewable resource. Over the […]
