Basically Fermentation is an Anaerobic respiration (i.e. Oxidation of energy compounds in the absence of oxygen).That means the answer to your question is 'oxygen'.
oxygen
Aerobic fermentation occurs in an environment that contains air. Anaerobic fermentation occurs in one lacking air.
Fermentation
In alcoholic fermentation, oxygen will react with the alcohol to form acetic acid.
Aerobic fermentation occurs in an environment that contains air. Anaerobic fermentation occurs in one lacking air.
Fermentation occurs when living cells present on the skin of fruit and vegetables break down the sugars inside. This fermentation causes a chemical change in the food which gives it a different taste.
Fermentation normally occurs in an the absence of oxygen (called anaerobic) but is can occur in its presence
fermentation occurs in the absence of oxygen (anaerobic respiration). in muscle cells, when the blood supply is inadequate, anaerobic respiration takes place and the glucose is converted into lactic acid in the absence of oxygen :)
No mitochondrion breaks down food molecules in the absence of oxygen. In the absence of oxygen, glycolysis followed by fermentation occurs in the cytoplasm.
The two types of fermentation are alcoholic fermentation and lactic acid fermentation. Alcoholic fermentation is also referred to as ethanol fermentation.
Any respiratory reaction that takes place in the absence of oxygen is considered an anaerobic respiratory reaction. I would have to guess that that is the answer you are looking for.
fermentation occurs in the mitochondria actually.
Fermentation is sometimes known as anaerobic respiration - because it usually occurs in the absence of oxygen. However, fermentation is the extraction of energy by oxidation of organic compounds. It does not necessarily have to occur in anaerobic conditions.
Solid-state (substrate) fermentation (SSF) has been defined as the fermentation process occurring in the absence or near-absence of free water. Submerged is liquid state Fermentation
