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

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 […]

More Yeast Beasts for Biotech? JGI marks more strains for production possibilities

August 20, 2016 |

Yeast, they’re so small that they probably all look like twins, all work the same, do the same things. Not so, says DOE Joint Genome Insitute’s Robert Riley, who tells The Digest, “We might think of yeasts as simple unicellular, creatures similar to each other, but in fact their genetic diversity is like the difference […]

Researchers break through on oil production in yeast using advanced gene-editing tool

January 31, 2016 |

In California, a team led by a researcher at the University of California, Riverside has adapted the CRISPR-Cas9 gene editing system for use in a yeast strain that can produce useful lipids and polymers. The development will lead to new precursors for biofuels, specialty polymers, adhesives and fragrances. Published recently in the journal ACS Synthetic […]
