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.
There are two types of fermentation ususally studied in Biology: Alcoholic Fermentation and Lactic Acid Fermentation. Both types have the same reactants: Pyruvic acid and NADHâ¦, both of which are products of glycolysis. In alcoholic fermentation, the major products are alcohol and carbon dioxide.
