Scope of Microbiology

Scope of Microbiology

From our beds and mobile phones to parks and offices, Microorganisms are everywhere. Charles Darwin had rightly said, “We cannot fathom the marvelous complexity of an organic being, but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm, a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.” Where we see the microbes processing some of the most fundamental activities essential to the earth, the study of these minute organisms becomes important. This further makes a career in Microbiology one of the most sought-after ones. Through this blog, we will give you an insight into this small world and how the scope of Microbiology is vast. 

What is Microbiology?

Having mentioned that Microbiology is one of the most popular courses after BiPC, let us know what this area is all about. Microbiology is one of the branches of Biology which involves the study of bacteria, fungi, viruses, and other microscopic organisms that cannot be seen with a naked eye. A microbiologist identifies and examines the behaviour of certain microbes in given conditions and the impact they can have. Encompassing the elements of various other disciplines such as genetics, immunology, and molecular biology, the scope of Microbiology is huge.

Scope of Microbiology: Sub-disciplines

As discussed, the scope of Microbiology is very broad as it consists of various specializations under it which cover different aspects of this very field. Tabulated below are some of the most prominent and sought-after branches: 

Branch What Does it Study?
Bacteriology Bacteria
Mycology Fungi
Protozoology Protozoa
Phycology Algae
Parasitology  Parasites
Immunology Immune System
Virology Viruses

Scope of Microbiology: Key Employment Areas

The microbiologists today are in huge demand in a number of industries and sectors across the world. Not being limited to just one, here are the fields where the scope of microbiology is visibly high:

Food Microbiology Microorganisms in food industries are used in preparing various other food products, such as pickles, cheese, vinegar, alcohol, bread, green olives, etc.
Environmental Studies The scope of microbiology in this sector is vast. From understanding and using the microbes(primary decomposers) and bioremediation to pest control, microbiologists can work on an array of issues prevalent in this field.
Healthcare Sector Bacteria and other microbes are used to manufacture various Antibiotics and synthesize vitamins which is essential for the body. They are also used for gene therapy for treating genetic diseases. This is why the scope of microbiology in this field is increasing. 
Genetic Engineering The scope of microbiology in this discipline is vast due to the increasing popularity of the field. The genes of the microbes are manipulated in order to produce useful and valuable products such as hormones, enzymes, etc.

Listed below are some other areas where the scope of Microbiology is visible:

  • Agrochemistry biotechnology
  • Pollution control boards
  • Biorefineries
  • Hospitals 
  • Universities
  • Research Centres
  • Forensic Labs

Scope of Microbiology: Job Profiles

With the constant awareness of the usefulness of Microbiology, many people are flocking towards this field to pursue some of the high salary courses after 12th science. Enlisted below are the popular job profiles that an aspirant can head to for making a successful career in Microbiology: 


With an aim to devise and create products that can be used in scores of applications, a Biotechnologist carries extensive research on the physical, chemical, and genetic characteristics of microbes and produce user-friendly products. From agriculture and pharmaceutics to genetics and food sciences, the scope of microbiology while working as a biotechnologist is broad. 

Food Microbiologist

When we talk about the scope of microbiology, food microbiologist is a work profile that is very popular. These professionals work towards preventing foodborne diseases by conducting extensive research on the disease-causing microbes, their conditions, packaging of food, food poisoning, legislations, etc. You can work in educational institutes, NGO’s, government and private agencies, etc under this profile and can further amp up your knowledge by pursuing a Career in Food Biotechnology or related disciplines.

Medicinal Chemist

With an aim to identify, design, and optimize drugs using chemical compounds, the medicinal chemists play a pivotal role in the pharmaceutical sector. As a Medicinal Chemist, the scope of MIcrobiology is not only restricted to developing new drug formulations but also extends to devising new techniques through which drugs can be made. For those who want to establish a Career in Biochemistry, this can be an ideal role.


As discussed, the scope of microbiology is not only restricted to certain specific fields but has applications in other sectors too. A pharmacologist is one such profession where the microbiologists are in demand. Identifying and analyzing the link between living components and substances so as to formulate new medicinal products is the main task of such professionals. 


With applications in almost every sector, nanotechnology courses encompass the elements of chemistry, biology, physics, pharmacology, microbiology, etc. From identifying and finding solutions to infectious diseases to water and sewage treatment, the scope of Microbiology by working as a Nanotechnologist is immense. 

Technical Brewer

In the beer production industries, technical brewers are senior-level professionals who through their managerial and technical knowledge, oversee, manage and maintain the brewing process and equipment. Such experts should be adept in concepts related to biochemistry, microbiology, etc. 

Marine Biologist

A marine biologist is the one who studies marine life and identifies the causes disrupting the same. With various microorganisms like fungi, bacteria, algae forming an essential part of marine life, these professionals examine the physiological and behavioural process of various marine species and can also work on taxonomy and fossil microbiology. 

Clinical Scientist

Working in hospitals, clinics, laboratories, and research institutes, clinical scientists strive to use their knowledge in the field of medicine and biomedical research, that help the growth of living organisms, along with developing various medications and treatments for it.
