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...
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 ...
Yeast is a key ingredient in the fermentation process. Yeast has a crucial aromatic impact. Some yeast produce unique aromas , flavors , mouthfeel of wine , beer…. Yeasts are responsible for ~80% of the aromatic compounds that we can smell in wine. Yeast is also the crafter of many other fermented foods.
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 ...

Therefore it is important to notice that apart from bread, reduction of phytates by yeast phytases have been observed in other plant-derived foods such as in ‘Icacina mannii paste’, a traditional food in Senegal, during fermentation with S. cerevisiae and in ‘Tarhana’, a traditional Turkish fermented food, using baker's yeast as a phytase source .
