![]() Malfunctions can lead to cancer or birth defects. Importantly, the human versions of a number of yeast cell cycle and DNA repair genes have been found to be directly involved in human cell division. But humans are very complicated, so it is easier to establish basic principles in simple model organisms. Why is yeast relevant to biomedical research? Normal cell division is central to normal growth and development not only of yeast cells, but of humans as well. We have also made bread with it that was more successful and was actually tasty, although it is not as robust at rising as standard baker's yeast. ![]() Still, I've been told that pombe generates the largest number of foul-tasting compounds for any fermentation and it is typically viewed as a spoilagein winemaking. But of course, this is not a traditional method, so maybe it tastes better with millet. The sulfurous nose was very noticeable and increased with time. My lab has also tried brewing with pombe with unimpressive results. The taste is described as sour, or even foul.If you use fission yeast to brew with malt and hops (European style), the results are disappointing. Other sources suggest that beer-making is traditionally women's work, and I have a story- quilt from Zimbabwe that illustrates beer making. When I visited Kenya, I was told that traaditional pombe is buried for a period to rot-er, ferment. Millet was used for most beer in the 19th c, other grains today. pombe particularly useful in the laboratory, where we use it as a model system for cell division.Īn aside about beer: Various sources describe pombe beer as millet, maize, or sorghum based. pombe and closely related species have been isolated from grape juice, kambucha tea, and arak. pombe was originally isolated from a millet beer (see the history pages for the original characterization of S. However, the species that we study is the fission yeast Schizosaccharomyces pombe, which is a very different organism, not harmful, and easy to grow. ![]() "Yeast infections" typically come from the pathogenic species Candida albicans. Most people are familiar with brewer's or baker's yeast, Saccharomyces cerevisiae, which is a popular laboratory model system as well as a well-domesticated servant. You can find out more about various yeasts by visiting the web pages listed in the yeast virtual library. Yeast is a very general term, and covers a broad range of unicellular fungi that are only vaguely related.
