  2. Ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fermentation

    Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.

  3. Fermentation in winemaking - Wikipedia

    en.wikipedia.org/wiki/Fermentation_in_winemaking

    Carbon dioxide activity is visible during the fermentation process in the form of bubbles in the must. During fermentation, there are several factors that winemakers take into consideration, with the most influential to ethanol production being sugar content in the must, the yeast strain used, and the fermentation temperature. [15]

  4. Fermentation - Wikipedia

    en.wikipedia.org/wiki/Fermentation

    Fermentation is a type of redox metabolism carried out in the absence of oxygen. [1] [2] During fermentation, organic molecules (e.g., glucose) are catabolized and donate electrons to other organic molecules. In the process, ATP and organic end products (e.g., lactate) are formed. Because oxygen is not required, it is an alternative to aerobic ...

  5. Acetone–butanol–ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Acetone–butanol–ethanol...

    The process may be likened to how yeast ferments sugars to produce ethanol for wine, beer, or fuel, but the organisms that carry out the ABE fermentation are strictly anaerobic (obligate anaerobes). The ABE fermentation produces solvents in a ratio of 3 parts acetone, 6 parts butanol to 1 part ethanol.

  6. Brewing - Wikipedia

    en.wikipedia.org/wiki/Brewing

    Steps in the brewing process include malting, milling, mashing, lautering, boiling, fermenting, conditioning, filtering, and packaging. There are three main fermentation methods: warm, cool and spontaneous. Fermentation may take place in an open or closed fermenting vessel; a secondary fermentation may also occur in the cask or bottle.

  7. Cellulosic ethanol - Wikipedia

    en.wikipedia.org/wiki/Cellulosic_ethanol

    Instead of sugar fermentation with yeast, this process uses Clostridium ljungdahlii bacteria. [41] This microorganism will ingest carbon monoxide, carbon dioxide and hydrogen and produce ethanol and water. The process can thus be broken into three steps:

    Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...

  9. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Fermentation is the process of culturing yeast under favorable thermal conditions to produce alcohol. This process is carried out at around 35–40 °C (95–104 °F). Toxicity of ethanol to yeast limits the ethanol concentration obtainable by brewing; higher concentrations, therefore, are obtained by fortification or distillation. The most ...
