Branches of microbiology

The branches of microbiology can be classified into pure and applied sciences.

[1] Microbiology can be also classified based on taxonomy, in the cases of bacteriology, mycology, protozoology, and phycology.

In the more fundamental field the organisms are studied as the subject itself on a deeper (theoretical) level.

Applied microbiology refers to the fields where the micro-organisms are applied in certain processes such as brewing or fermentation.

The organisms itself are often not studied as such, but applied to sustain certain processes.
