Anaerobes all use fermentation.
Anaerobic respiration.
Aerobic fermentation makes energy, water and CO2 Anaerobic fermentation makes energy, water, alcohol and CO2.
Fermentation
Fermentation is anaerobic because it doesn't require oxygen to produce energy. Instead, it uses organic compounds as electron acceptors in the absence of oxygen. This process generates energy for the cell without the need for aerobic respiration.
Photosynthesis and fermentation both involve energy conversion processes in living organisms. While photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen, fermentation is an anaerobic process that converts sugars into energy in the absence of oxygen, producing either alcohol or lactic acid.
Fermentation and glycolysis are two examples of anaerobic chemical reactions where energy is produced without the presence of oxygen.
Organisms that are anaerobic do not require oxygen to generate energy, while aerobic organisms do. Anaerobic organisms can generate energy through processes like fermentation, which is less efficient than aerobic respiration. Aerobic organisms can produce more energy because aerobic respiration is a more efficient process that requires oxygen.
Yeast use fermentation (alcoholic fermentation). This produces carbon dioxide, alcohol, and some energy.
By using aerobic respiration and anaerobic fermentation Yersinia pestis are able to produce and consume hydrogen gas for energy.
If the organism grows in the OF-glucose medium exposed to air, it is likely undergoing oxidative metabolism. This is because air contains oxygen, which the organism can use through oxidative phosphorylation to generate energy. If the organism were fermentative, it would generate energy through fermentation pathways even in the presence of oxygen.
Anaerobic bacteria are organisms that can live in environments with little to no oxygen. They have adapted to generate energy through fermentation or anaerobic respiration. Some examples include clostridium and methanogens.
Anaerobic species are organisms that can live and grow in environments without oxygen. They typically produce energy through fermentation or anaerobic respiration. Anaerobic species often thrive in environments such as deep sea vents, wetlands, and the human digestive system.
