An aerobic microorganism is described as the type of organism that has the strict need for the consumption of diatomic oxygen to be able to live, it is classified as a facultative aerobic organism when it can live or not with the presence of oxygen.
The adjective aerobic is not only applied to the classification of an organism, it can also be used to describe an environment or a metabolic reaction, designating it the name of “aerobic environment” and “aerobic metabolism” respectively, in both situations oxygen is It is present in abundant quantities, (designating it as a microaerophilic environment when there is oxygen in small quantities but it is not nonexistent), as an example of aerobic metabolism, photosynthesis can be citedOxygen which contributes large amounts of oxygen to the environment whose oxygen is used by eukaryotic cells thanks to the presence of the mitochondria in charge of carrying out the cellular respiration process.
This term is mainly used in the classification of pathogenic microorganisms such as bacteria, aeobic bacteria, as their surname indicates, have a need to inhabit environments rich in diatomic oxygen to be able to grow, proliferate and differentiate in a timely manner, that is, they are a type of bacteria that perform cellular respiration, according to the need for oxygen we can classify them into several groups: strict aerobic bacteria (obligate aerobes) these require oxygen to carry out their metabolic processes, facultative anaerobic bacteria can use oxygen and in turn also work without it, microaerophilic bacteriathey use oxygen at low concentrations, aerotolerant bacteria can live in the presence of oxygen but do not use it metabolically.
