Dear Sohom, There is vast scope in the field of microbiology due to the advancement in the field of science and technology. The scope in this field is immense due to the involvement of microbiology in many fields like medicine, pharmacy, diary, industry, clinical research, water industry, agriculture, chemical technology and nanotechnology. A undergraduate degree in microbiology gives you the opportunity to work at science laboratories and pathology labs. If you have a PG in microbiology, you can work in microbiology based industries like pharmacy, dairy, breweries, distilleries, enzyme, etc. and you also can pursue PhD. Students who complete PhD can take up teaching at universities and PG colleges. They can also take up a post-doctoral research. Based on the field you choose and the degree you have, average salary of a microbiologist is  5 laksh per year. Though, anything between  3 lakhs to 10 lakhs (approx.) per year can be expected.
