What is Difference Between Aerobic And Anaerobic Bacteria?

Difference Between Aerobic And Anaerobic Bacteria is that Aerobic Bacteria are  The organisms that need diatomic oxygen to live or develop can be called aerobic or aerobic. The adjective “aerobic” applies not only to organisms but also to the processes involved (“aerobic metabolism”) and to the environments where they are performed. Difference Between Aerobic And Anaerobic Bacteria

An “aerobic environment” is one that is rich in oxygen, unlike an anaerobic one, where oxygen is absent, or a microaerophilic one, where oxygen is at a very low concentration.

Aerobic metabolism (respiration) emerged in evolution after oxygenic photosynthesis, the most common form of photosynthesis, released oxygen into the atmosphere, which had been very scarce until then. Initially, it represented a way to counteract the toxicity of oxygen, rather than a way to take advantage of it.

As the oxidation of glucose and other substances releases much more energy than their anaerobic use, for example, fermentation, aerobic beings soon became the dominant organisms on Earth.

The common ancestor of eukaryotic organisms (with nucleated cells) acquired the ability to perform aerobic metabolism by integrating an aerobic bacterium as a permanent organelle, the mitochondria (endosymbiosis theory).

Aerobiosis, a process known as cellular respiration, uses oxygen for oxidation of the substrate (for example sugars and fats for energy).

A good example could be the oxidation of glucose (a monosaccharide) in aerobic respiration.

C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + 38 ATP
Giving around 2,880 kJmol-1 Oxygen is used during glucose oxidation and produces water
Anaerobic organism

Anaerobic or anaerobic organisms are those that do not use oxygen (O2) in their metabolism, more precisely that the final electron acceptor is another substance other than oxygen.

If the electron acceptor is an organic molecule (pyruvate, acetaldehyde, etc.) it is a fermentative metabolism; If the final acceptor is an inorganic molecule other than oxygen (sulfate, carbonate, etc.) it is anaerobic respiration.

The concept opposes that of the aerobic organism, in whose metabolism oxygen is used as the final electron acceptor.
IN a test tube activate the yeast at 37 ° with sucrose
use dyes
in one it is the yeast and in the second tube vinegar is placed and they are placed under the microscope after having activated these two as we mentioned it with sucrose
finally to observe under the microscope a few drops of cotton blue were placed.
If the difference between an aerobic and an anaerobic microorganism could be observed. Difference Between Aerobic And Anaerobic Bacteria
