What are the usefulness of microbial physiology study data f

Solution

It is necessary to identify related microorganisms and to group them for industrial and clinical applications. It is difficult and will not be accurate to decide closeness by observing their external features. So observing the physiological characters like their cell structure, growth, metabolism etc. give us idea to classify the organism. A better example to explain this concept would be the closeness between dolphin and cow than that of dolphin and fish.
