Yeast strain can increase ethanol production by 15.5%

Yeast strain can increase ethanol production by 15.5%

April 14, 2019 |

In India, researchers from the International Centre for Genetic Engineering and Biotechnology, DBT-ICGEB Centre for Advanced Bioenergy Research discovered that a robust yeast strain can produce up to 15.5% more ethanol when glucose or lignocellulose biomass — rice and wheat straw — is fermented and has been isolated. With India’s biofuel target going from the […]

Royal DSM and Lallemand conclude license agreement

Royal DSM and Lallemand conclude license agreement

April 7, 2019 |

In Illinois, Royal DSM and Canada-based Lallemand Inc. signed a joint agreement under which DSM grants to Lallemand a non-exclusive, royalty bearing license to DSM’s low-glycerol yeast technology patents (U.S. Patent No. 8,795,998). The license agreement is part of a settlement that was reached following a 2018 US Federal Court jury verdict in Wisconsin. The […]

Lallemand and Toyota sign agreement for new cellulosic yeast strains

Lallemand and Toyota sign agreement for new cellulosic yeast strains

March 24, 2019 |

In Georgia, Lallemand Biofuels & Distilled Spirits signed an agreement with Toyota Motor Corporation to produce and market a new portfolio of yeast strains “TOYOTA XyloAce” for cellulosic ethanol production in North America. Toyota, through the use of gene recombination technology, has recently developed new yeast strains that will play an important role in the […]

Great Lakes Bioenergy Research Center find four-gene cluster in yeast that produce pulcherrimin

Great Lakes Bioenergy Research Center find four-gene cluster in yeast that produce pulcherrimin

January 14, 2019 |

In Michigan, yeasts are complex organisms that may become the workhorses of biofuel production. To move yeasts into this larger role, scientists need to understand the genetic machinery that leads to the production of complex molecules like the iron-binding molecule pulcherrimin in budding yeasts. Great Lakes Bioenergy Research Center scientists revealed a four-gene cluster associated […]

University of Groningen researchers discover why some yeast produces ethanol

University of Groningen researchers discover why some yeast produces ethanol

January 7, 2019 |

In the Netherlands, University of Groningen scientists think they have figured out why some yeast cells produce ethanol: yeast cells produce ethanol as a ‘safety valve’ to prevent overload when their metabolic operation reaches a critical level. The new theory, which was published in Nature Metabolism on 7 January, could have far-reaching implications, as it […]

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 […]

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, […]

Tufts researchers genetically modify yeast to consume xylose

Tufts researchers genetically modify yeast to consume xylose

April 4, 2018 |

In Texas, researchers at Tufts University have created a genetically modified yeast that can more efficiently consume a novel nutrient, xylose, enabling the yeast to grow faster and to higher cell densities, raising the prospect of a significantly faster path toward the design of new synthetic organisms for industrial applications, according to a study published […]

Researchers use light to boost biofuel production from yeast

Researchers use light to boost biofuel production from yeast

April 2, 2018 |

In New Jersey, researchers at the Andlinger Center for Energy and the Environment use 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 a technology called optogenetics—involving light to control cellular processes—to turn […]

How EtOH production affects yeast health: 4 tips for dealing with ethanol stress

How EtOH production affects yeast health: 4 tips for dealing with ethanol stress

December 18, 2017 |

By Dale Earls, Scientist, Novozymes Special to The Digest It turns out that too much of a good thing can actually be a bad thing—even when it comes to ethanol. At least in terms of the fermentation process. In commercial yeasts available today, as fermentation progresses and the concentration of ethanol rises, yeast cells are […]
