Microbial physiology is the study of the various microbial processes, viz., biochemical processes, metabolic processes, growth & functioning. 

The first or the basic thing that any microbiology research begins is with the characterization of the microbes- it’s identification, physiology and genomics. It all starts with the microbial cultures. Same goes for identification of either a pathogenic or a non-pathogenic and also a beneficial microbe- first characterization will be the ability of the microbe to grow and develop in a specific media, to differentiate the pathogenic microorganisms and a non-pathogenic microbes by a streak plate method. It is obvious that most of the pathogenic bacteria can grow on any given nutrient media, and any further addition will only aid in their growth, especially the addition of blood, in Blood Agar Medium, which will assist us in the identification of the bacteria, and its further genomic classification. Which, later on takes us to the physiology of the microbes, where one observes the time of the cell division, type of the cell division, and the type of the bacteria, whether they are autotrophs or heterotrophs, and the major nutrients, growth factors & environmental factors required for its growth and which ones have a negative impact on its growth.
