Princeton researchers find fundamental mechanism of isobutanol’s toxic effect

Princeton researchers find fundamental mechanism of isobutanol’s toxic effect

April 28, 2020 |

In New Jersey, in a study published in the journal Cell Systems, researchers from Princeton University revealed a fundamental mechanism of isobutanol’s toxic effect. They found that in the presence of isobutanol, yeast behave like they are starving, even though they are in rich nutritious broth, causing them to slow their growth and metabolism. The […]

Princeton researchers discover genetic switch in yeast to boost isobutanol production

Princeton researchers discover genetic switch in yeast to boost isobutanol production

November 14, 2019 |

In New Jersey, yeast only creates a tiny amount of isobutanol. Now researchers at Princeton University have discovered a genetic switch that significantly ramps up production. The findings, published Nov. 13 in the journal Cell Systems, showed that the researchers were able to increase isobutanol production by roughly five times over that of standard yeast […]

WPI researchers develop novel process to produce isobutanol cheaper

April 18, 2019 |

In Massachusetts, taking a step closer to a “green” replacement for fossil fuels, a research team that includes a chemical engineer at Worcester Polytechnic Institute (WPI) has developed a novel process using an unusual solvent and an exotic microorganism that may make it possible to manufacture isobutanol and other biofuels more economically. In a paper […]

UW-Madison researchers find red pigment can improve isobutanol production

UW-Madison researchers find red pigment can improve isobutanol production

November 5, 2018 |

In Wisconsin, a compound that has scientists seeing red may hold the key to engineering yeasts that produce better biofuels. A red pigment called pulcherrimin, naturally produced by several strains of wild yeasts, is synthesized in part through the same biochemical pathway that researchers hope to use to improve production of isobutanol, a promising biofuel […]

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 […]

Researchers use light to turn yeast into biochemical factories

Researchers use light to turn yeast into biochemical factories

March 23, 2018 |

In New Jersey, Princeton University researchers used light to control genetically modified yeast and increase its output of commercially valuable chemicals. The team used light to enhance the production of biofuels, drugs and commercial chemicals in bioreactors, which contain microorganisms such as yeast that have been metabolically engineered to make biological products. The team uses […]
