Jan 22, 2011 · Fermentation: A Discussion In a general sense, fermentation is the conversion of a carbohydrate such as sugar into an acid or an alcohol. More specifically, fermentation can refer to the use of yeast to change sugar into alcohol or the use of bacteria to create lactic acid in certain foods.
Butanol-acetone fermentation. Butanol and acetone were discovered as the main end products of fermentation by Clostridium acetobutylicum during the World War I. This discovery solved a critical problem of explosives manufacture (acetone is required in the manufacture gunpowder) and is said to have affected the outcome of the War.
The End Products of Fermentation are produced from different types of fermentation: Ethanol and carbon dioxide are produced from alcohol fermentation (ethanol fermentation). They are produced by fungi, notably by yeast. Lactic acids are produced from homolactic acid fermentation.
Dec 01, 2020 · Fermentation is the anaerobic, energy-yielding breakdown of organic substances via bacteria, yeast or other microorganisms. Milk sugar, better known as lactose, imparts a characteristic sweetness to dairy products.
Suppose your yeast experiments produce 500 ml (0.5 liters) of gas (CO 2) in the glucose fermentation. The volume produced is equivalent to (0.5 liters) • (0.042 mole/liter) = 0.021 moles of CO 2. If 0.021 moles of CO 2 are produced, how much ethanol was produced? Glucose (a 6 carbon sugar) yields two ethanol molecules and two CO 2 molecules. For
