In the previous article, I have already discussed What is Microbiology? And History Of Microbiology. In this article, we will discuss Different branches of Microbiology and their purpose.
What is Microbiology? Microbiology is an advanced biology course that studies unicellular (single cell), multicellular (cell colony), or acellular (lacking cells) microorganisms, including bacteria, archaea, algae, fungi, protozoa, and viruses.
Branches of Microbiology
There are two branches of Microbiology such as Pure Microbiology and Applied Microbiology. Microbiology can be also classified into bacteriology, mycology, protozoology, and phycology, etc based on their taxonomy.
There is appreciable overlap between the particular branches of microbiology with one another and with different disciplines, and sure facets of those branches can prolong past the normal scope of microbiology In common the sphere of microbiology could be divided within the extra elementary department (pure microbiology) and the utilized microbiology (biotechnology).
In the extra elementary discipline, the organisms are studied as the topic itself on a deeper (theoretical) stage. Applied microbiology refers back to the fields the place the micro-organisms are utilized in sure processes reminiscent of brewing or fermentation. The organisms itself are sometimes not studied as such, however, utilized to maintain sure processes.
