  1. Yeast

    Yeasts are eukaryotic microorganisms classified in the kingdom Fungi, with 1,500 species currently described. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation of strings of connected budding cells known as pseudohyphae, or false hyphae, as seen in most molds. Yeast size can vary greatly depending on the species, typically measuring 3–4 µm in diameter, although some yeasts can reach over 40 µm. Most yeasts reproduce asexually by mitosis, and many do so by an asymmetric division process called budding. By fermentation, the yeast species Saccharomyces cerevisiae converts carbohydrates to carbon dioxide and alcohols – for thousands of years the carbon dioxide has been used in baking and the alcohol in alcoholic beverages. It is also a centrally important model organism in modern cell biology research, and is one of the most thoroughly researched eukaryotic microorganisms. Researchers have used it to gather information about the biology of the eukaryotic cell and ultimately human biology. Other species of yeasts, such as Candida albicans, are opportunistic pathogens and can cause infections in humans. Yeasts have recently been used to generate electricity in microbial fuel cells, and produce ethanol for the biofuel industry.

Examples of yeast in a Sentence

  1. Elizabeth Sattely:

    Producing plant-derived drugs in easy-to-grow plants or baker's yeast in many cases will be a much more efficient way to make these drugs, this is currently being done for artemisinin (a malaria drug derived from the sweet wormwood plant), and will likely be the way we make morphine (derived from poppies) in the future.

  2. Cyril Brun:

    The yeast converts the sugar into alcohol, and because of the pressure, carbon dioxide is created, providing a shower of bubbles.

  3. Julianna Schantz-Dunn:

    If you randomly self-treat and it’s not a yeast infection, you can make the problem worse.

  4. Di Maio:

    The key to the process is to design the pressure release rate not to stress the dough, which likes to expand gently, we mainly studied how dough behaves with and without yeast -- how the softness changes with leavening( rising), and how the dough responds to a temperature program during baking.

  5. Julianna Schantz-Dunn:

    You may feel some itching or painful urination, but the symptoms may not be as severe as you’d think, i’ve seen people try to treat herpes with a topical yeast medication—and that doesn’t do much.
