During fermentation, yeast cells convert cereal-derived sugars into ethanol and CO 2. At the same time, hundreds of secondary metabolites that influence the aroma and taste of beer are produced. Variation in these metabolites across different yeast strains is what allows yeast to so uniquely influence beer flavor [9].

What makes yeast such a useful model organism? An important feature of yeasts (especially Saccharomyces cerevisiae - a.k.a. S. cerevisiae) is that their cells, like ours, are eukaryotic – meaning they have a nucleus containing DNA packaged into chromosomes. And although it may seem like yeast and humans have very little in common, at least 20 perce...
Over the last several decades, researchers have been tirelessly interrogating all of the mutations that cause cancer in humans. Dr. Leeland Hartwell, a biologist and 2001 Nobel Laureate, was one of the first scientists to discover some of the mutations involved in cancer. Since then, many of the mutations found so far are in genes involved in some ...
What would happen if scientists were able to expedite their research by several orders of magnitude. What if multiple expertiments could be run at the same time, with data delivered almost instantaneously? How much more quickly could they target new drugs and therapies to treat humanity's most deadly diseases? Fenologica's platform quickly performs...
3.1 General characteristics. Yeasts are one-celled fungi, 5~10 μm in size. Yeast cells are usually spherical, cylindrical, or oval and are important for their ability to ferment the carbohydrates within various substances. They are widespread in nature, existing in soil and on plants.
The basic aerobic alcoholic fermentation ability was subsequently “upgraded” in several lineages by evolving additional regulatory steps, such as glucose repression in the S. cerevisiae clade, to achieve a more precise metabolic control. Keywords: alcoholic fermentation, yeast, evolution, life strategy, carbon metabolism. Introduction
Oct 18, 2021 · Fermentation is a process in which sugars are transformed into a new product through chemical reactions carried out by microorganisms. Since ancient times, humans have taken advantage of the natural fermentation process to develop many products, including foods, medicines, and fuels. In this article, we provide a close look at the history of fermentation, demonstrating why this natural process ...
Therefore, brewers and wine makers can select different strains of yeast to produce different alcohol contents in their fermented beverages, which range from 5 percent to 21 percent of alcohol by ...

Jan 4, 2024 · The history of yeast Saccharomyces cerevisiae, aka brewer’s or baker’s yeast, is intertwined with our own. Initially domesticated 8,000 years ago to provide sustenance to our ancestors, for the past 150 years, yeast has served as a model research subject and a platform for technology. In this review, we highlight many ways in which yeast has served to catalyze the fields of functional ...
