Career In Microbiology and Its Importance

Microbiology is the study of microscopic organisms like bacteria, viruses, fungi and some parasites, and it is the field that explains how these organisms is involved in different biological and environmental activities. A career in microbiology is followed when a person study these microbes and work with them in laboratories or research centers.

It is common that students work as clinical laboratory professionals where the disease-causing organisms is identified from blood, urine or other samples which is important for diagnosis and treatment. It is also the process used in many hospitals because correct detection of microbes is required to control infections.

In research areas, the microbiologists work as scientists in universities or institutes. Here the main work is performing experiments, maintaining cultures, studying microbial behavior and teaching the students.

It is often seen that some researchers is involved in explaining new mechanisms of microbes and developing new ideas for medicines or vaccines. Besides these, industry also use microbiologists because the major source of many products is microbial activity. These include antibiotics, enzymes, fermented foods, vaccines, biofuels and other useful compounds.

A career in microbiology is important because it helps in early detection of infectious diseases and allows the development of control strategies. It is also the field used in studying antimicrobial resistance (AMR) which is a growing problem as many microbes become resistant to drugs. Microbiology is the process that support environmental balance through bioremediation where microbes degrade pollutants and help to clean soil and water.

Among the important roles, microbiology also contribute to biotechnology where microbes act as biofactories for producing useful products. Thus, this field provide many career options and also maintain health, industry and environment through its applications.

Career In Microbiology

It is the study of microorganisms and their various activities. A microbiologist is a scientist who works with these organisms, and the training may include a bachelor’s degree, master’s degree, or a doctoral program in microbiology. It is the process where an individual learn about different groups of microbes and how these microbes is connected with human, animals, plants and the environment.

There are many fields inside microbiology. It is sometimes focused only on one group of microorganisms and the reactions shown by them. These are explained below in simple points.

Types

• Bacteriologist– It is the study of bacteriology. The structure, activities and functions of bacteria is examined here.
• Phycologist– These are scientists who study algae. The activities of algae and their different forms is studied.
• Protozoologist– It is the process where protozoa and their movements is studied.
• Mycologist– These scientists study fungi. The diseases caused by fungi and their growth pattern is observed.
• Virologist– Virology is the study of viruses and their effects on living cells. Some virologists also study prions and viroids which is even smaller than viruses.

There are also fields which is applied in industry, agriculture, medicine and ecology. These are some of the main fields–

1. Biotechnology (Industrial Microbiology)

It is the use of microorganisms in industries. It is the process used in formation of products like beer, wine, alcohol, enzymes, vitamins and antibiotics. Industrial microbiologists monitor the growth of microbes that is required for these industries. Applied microbiologists also work for developing new products and effective antibiotics.

2. Environmental Microbiology and Bioremediation

Environmental microbiology is connected with water, soil and sewage treatment. Microorganisms help in purifying wastewater in sewage disposal plants. Some microbes break down metals and minerals. Bioremediation is the process where microbes is used to clean landfills and toxic wastes. These are important for maintaining environment quality.

3. Agricultural Microbiology

This field study the role of microbes in soil fertility, nutrient cycles (carbon, nitrogen, phosphorus, sulfur), plant diseases, and digestion in ruminants. Food microbiologists monitor food processing, cooking and storage. Dairy microbiologists study milk grading, pasteurization and cheese production.

4. Veterinary Microbiology

It is the study of infectious diseases in animals. Many microorganisms cause diseases in livestock and pets. The diseases transmitted from animals to humans is called zoonotic diseases. It is a good field for those interested in animals.

5. Medical and Clinical Microbiology

It is the study of pathogens and the diseases caused by them. It is connected with epidemiology, disease transmission, aseptic methods, immunology, and vaccines production. The process help in controlling infections.

6. Microbial Genetics and Genetic Engineering

It is the study of microbial DNA, genes, plasmids and chromosomes. Genetic engineering is the process where foreign genes is inserted into microorganisms so that they produce useful products. It is used in agriculture, medicine and industry.

7. Microbial Physiology

It examine the structure and functions of microbial cells. Many reactions seen in microbial cells is similar to other cells so this field is important for biochemistry.

8. Paleomicrobiology

It is the study of ancient microbes. Molecular fossils found in old rocks show that life existed billions of years ago. Microbial DNA from mummies and bones is studied to understand ancient diseases.

9. Parasitology

It is the study of parasites. These include parasitic protozoa, helminths (worms) and arthropods. Their life cycle and diseases caused by them is examined.

10. Sanitary Microbiology

It deals with sewage disposal, garbage processing and water purification. Sanitary microbiologists also inspect food handling areas to prevent contamination.
