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, […]

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 […]

Keeping yeast fit and healthy: combating organic acids in fermentation

Keeping yeast fit and healthy: combating organic acids in fermentation

October 23, 2017 |

By Amanda Moser, Senior Scientist, Novozymes Special to The Digest It’s harvest time, and that means organic acids—a common stressor for yeast—are a top-of-mind concern for ethanol producers. But while some yeasts are more resilient than others, most still require constant attention; after all, each stressor can potentially reduce performance, and those reductions can quickly […]

German researchers boost metabolism of baker’s yeast to improve yields

German researchers boost metabolism of baker’s yeast to improve yields

September 18, 2017 |

In Germany, currently, making products such as fuels, synthetic materials or pharmaceuticals from renewable raw materials lacks efficiency because the microorganisms process the raw materials very slowly and generate many unwanted by-products. Biotechnologists at Goethe University Frankfurt have now succeeded in optimizing sugar utilization in baker’s yeast. Researchers from the Institute of Molecular Biosciences at […]

Thai researchers use yeast to lower cassava ethanol production costs

Thai researchers use yeast to lower cassava ethanol production costs

March 22, 2017 |

In Thailand, researchers from the Thailand Institute of Science and Technological Research have discovered that the yeast Saccharomyces Cerevisiae can be used to better produce ethanol from cassava thanks to its heat resistance and speed in consuming sugars, reducing production costs down to those of molasses. The research leading to the discovery took 18 months […]

MIT engineers reprogram yeast to convert sugars to fats more efficiently

MIT engineers reprogram yeast to convert sugars to fats more efficiently

February 14, 2017 |

In Massachusetts, MIT engineers have genetically reprogrammed a strain of yeast so that it converts sugars to fats much more efficiently, an advance that could make possible the renewable production of high-energy fuels such as diesel. The researchers modified the metabolic pathways of yeast that naturally produce large quantities of lipids, to make them about […]
