Bacterioplankton are bacteria and archaea, which play an important role in remineralising organic material down the water column (note that many phytoplankton are also bacterioplankton). Plankton are found throughout the oceans, seas and lakes of Earth.
Beer fermenting at a brewery. Fermentation in food processing is the conversion of carbohydrates to alcohols and carbon dioxide or organic acids using yeasts, bacteria, or a combination thereof, under anaerobic conditions.Fermentation usually implies that the action of microorganisms is desirable.eer and bread, two major uses of fermentation in food. The primary benefit of fermentation is the conversion of sugars and other carbohydrates into preservative organic acids, e.g. converting juice into wine, grains into beer, carbohydrates into carbon dioxide to leaven bread, and sugars in vegetables.
Fermentation starts with pyruvate (the end product of glycolysis). Depending on the organism, pyruvate can either be fermented into ethanol (a fancy name for alcohol) or lactate (lactic acid). Fermentation releases CO 2, but does not make any ATP â all ATP during anaerobic respiration is produced during glycolysis.Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell.ermentation starts with pyruvate (the end product of glycolysis).
