Aerobic fermentation or aerobic glycolysis is a metabolic ... have the largest expression difference between aerobic fermentative ... and uncontaminated water. ...
The organic or inorganic substances (e.g., oxygen) used as electron acceptors needed in the catabolic processes of aerobic or anaerobic respiration and fermentation are not taken into account here. For example, plants are lithotrophs because they use water as their electron donor for the electron transport chain across the thylakoid membrane.
This definition distinguishes fermentation from aerobic respiration, where oxygen is the acceptor and types of anaerobic respiration, where an inorganic species is the acceptor. [citation needed] Fermentation had been defined differently in the past. In 1876, Louis Pasteur described it as "la vie sans air" (life without air). [7]
Frequently referenced, but often misunderstood, the difference between the terms "aerobic" and "anaerobic" seems small but is actually big (and important). Frequently referenced, but often ...
In an aerobic system the majority of the energy in the starting material is released as heat by their oxidisation into carbon dioxide and water. [3] Composting systems typically include organisms such as fungi that are able to break down lignin and celluloses to a greater extent than anaerobic bacteria. [4]
Numerous fermentation pathways exist such as lactic acid fermentation, mixed acid fermentation, 2-3 butanediol fermentation where organic compounds are reduced to organic acids and alcohol. [8] [4] The energy yield of anaerobic respiration and fermentation (i.e. the number of ATP molecules generated) is less than in aerobic respiration. [8]
The main difference between these processes is that anaerobic reactions produce methane, while aerobic reactions do not (however, both reactions produce carbon dioxide, water, some type of residue, and a new biomass). [8]
They gather mostly at the top because aerobic respiration generates more ATP than either fermentation or anaerobic respiration. 4: Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen. They gather in the upper part of the test tube but not the very top.
