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...
Each sugar sample was dissolved in 100 mL of water and then 7.0 g of yeast was added. Fermentation rate and yeast concentration. After seeing that the rate of yeast fermentation does not depend on the concentration of sugar under the conditions of our experiments, we decided to see if it depends on the concentration of the yeast.
Dec 8, 2021 · Yeast has been an essential tool to our society since the beginning of time. Beer, bread, and wine all use yeast due to their ability to undergo fermentation. 1 Not only does yeast contribute to creating yummy food, but it also plays an important role in biomedical research. Many scientists, including some at Penn State College of Medicine ...
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 ...
Jul 12, 2023 · Two common types of fermentation are named for their end products, alcoholic fermentation and lactic acid fermentation. Fermentation produces organic end products that still contain high-energy electrons. Fermentation does not fully oxidize glucose, and yields only 2 net molecules of ATP, along with organic end products. Figure 1.
