  2. Yeast - Wikipedia

    en.wikipedia.org/wiki/Yeast

    At the time, it was the most complex organism to have its full genome sequenced, and the work of seven years and the involvement of more than 100 laboratories to accomplish. [107] The second yeast species to have its genome sequenced was Schizosaccharomyces pombe, which was completed in 2002.

  3. Saccharomyces cerevisiae - Wikipedia

    en.wikipedia.org/wiki/Saccharomyces_cerevisiae

    Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.

  4. Elephant's toothpaste - Wikipedia

    en.wikipedia.org/wiki/Elephant's_toothpaste

    Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide.

  5. Yeast extract - Wikipedia

    en.wikipedia.org/wiki/Yeast_extract

    Yeast extract is a common ingredient in commercially prepared soups (canned, frozen, or deli). [1] [2] It is a flavor enhancer like monosodium glutamate (MSG).Yeast extracts consist of the cell contents of yeast without the cell walls; [3] they are used as food additives or flavorings, or as nutrients for bacterial culture media.

  6. Baker's yeast - Wikipedia

    en.wikipedia.org/wiki/Baker's_yeast

    Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...

  7. Yeast assimilable nitrogen - Wikipedia

    en.wikipedia.org/wiki/Yeast_assimilable_nitrogen

    Yeast need a reliable source of nitrogen in forms that they can assimilate in order to successfully complete fermentation. Yeast assimilable nitrogen or YAN is the combination of free amino nitrogen (FAN), ammonia (NH 3) and ammonium (NH 4 +) that is available for a yeast, e.g. the wine yeast Saccharomyces cerevisiae, to use during fermentation.

  8. Aerobic fermentation - Wikipedia

    en.wikipedia.org/wiki/Aerobic_fermentation

    However, the yeast still had to use a portion of the sugar it consumes to produce ethanol. [2] Crabtree-positive yeasts also have increased glycolytic flow, or increased uptake of glucose and conversion to pyruvate, which compensates for using a portion of the glucose to produce ethanol rather than biomass. [ 9 ]

  9. Candida albicans - Wikipedia

    en.wikipedia.org/wiki/Candida_albicans

    Candida albicans is an opportunistic pathogenic yeast [5] that is a common member of the human gut flora.It can also survive outside the human body. [6] [7] It is detected in the gastrointestinal tract and mouth in 40–60% of healthy adults.
