Microbial Physiology

Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.

Chemotaxis

The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.
