I don't understand what aerobic and anaerobic fermentation is. I thought fermentation was a anaerobic process in the first place.
basically anaerobic will require oxygen within the fermentation process. where as aerobic will produce pyruvites to help with the fermentation process. this will in turn the process of glycolysis to begin and thus will begin celluar respiration. aerobic requires no air.
this is a process of metabolism. humans can't ferment alcohol(aerobic fermentation) because we don't have the genetic code to do so. all our cells requires energy in thus requiring oxygen.
aerobic fermentation is in the presence of O2 Aerobic fermentation: in which the substrate is
used for organism
growth, useful either for
water treatment or
anaerobic fermentation is in the absence of O2 like
Ethanol fermentation (performed by yeast and some types of bacteria) breaks the pyruvate down into ethanol and carbon dioxide. It is important in bread-making, brewing, and wine-making. Usually only one of the products is desired; in bread-making, the alcohol is baked out, and, in alcohol production, the carbon dioxide is released into the atmosphere or used for carbonating the beverage. When the ferment has a high concentration of pectin, minute quantities of methanol can be produced.
Lactic acid fermentation breaks down the pyruvate into lactic acid. It occurs in the muscles of animals when they need energy faster than the blood can supply oxygen. It also occurs in some kinds of bacteria and some fungi. It is this type of bacteria that converts lactose into lactic acid in yogurt, giving it its sour taste. These lactic acid bacteria can be classed as homofermentative, where the end product is mostly lactate, or heterofermentative, where some lactate is further metabolized and results in carbon dioxide, acetate or other metabolic products.
The main difference is that of presence or absence of oxygen and formation of more dangerous byproducts in anaerobic fermantation.
Not always all the Fermenttion are anaerobic! First Know that fermentation is the breaking of Carbohydrate. In anaerobic Fermentation, no oxygen is supplied
C6H12O6 [Gulcose] -Gives 2 C2H5OH [Ethanol] + 2CO2 [Carbon Di oxode]
But in an aerobic
C6H12O6 + O2 Gives C2H5OH + CO2
Aerobic fermentation requires the presence of oxygen, while anaerobic fermentation does not require oxygen.
