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.
Primary fermentation usually takes between three to seven days to complete. It goes by much more quickly than secondary fermentation because wine must is a much more fertile environment for the yeast. Sugar and oxygen levels are high during primary fermentation and there are plenty of nutrients.
