Microbiologist

Growing and identifying bacteria, viruses and fungi; testing water, food, medicines and clinical samples for germs; running diagnostic tests; keeping lab records; following strict safety and cleanliness rules; writing reports for doctors, food makers or pharma teams.

A day in the work
A microbiologist usually starts the morning by checking cultures and equipment, such as incubators and microscopes. Most of the day goes on sample testing, plating, staining and reading results under a microscope. Afternoons often go to recording data, checking results against standards and writing a report for a doctor, a food maker or a pharma team. Lab rules on gloves, masks and waste disposal apply all day.

1. Step 1 · Class 11–12Choose Science with Physics, Chemistry and Biology. Build good lab habits and keep your Biology practicals neat, since many colleges count practical marks. (reported — check with the official body)
2. Step 2 · Class 12Aim for at least 50% overall, and check each college's cut-off. If you want a central or Delhi university, check whether it uses CUET UG for B.Sc admission. (reported — check with the official body)
3. Step 3 · 3 yearsComplete a B.Sc in Microbiology. Practicals cover culture techniques, staining, microscopy, immunology and molecular biology. (reported — check with the official body)
4. Step 4 · 2 yearsDo an M.Sc in Microbiology. Many employers in pharma, food testing and diagnostics look for a postgraduate degree for lab-in-charge or research roles.
5. Step 5 · OptionalTake CSIR-UGC NET (Life Sciences) or a university entrance test, then do a PhD for research, teaching or senior scientist posts.
6. Step 6 · Early careerWork as a lab analyst or research assistant in a pharma company, hospital lab, food-testing lab or environmental lab. Build a record of tests you have run and reports you have written.

Pay depends on the employer, the city and your qualification: a B.Sc often starts in a lab-assistant role, while an M.Sc or PhD opens up senior research and quality posts.

• Class 7–9Watch free school-level videos on bacteria, fungi and viruses and make a simple chart comparing them. Ask your Science teacher to show you a microscope.Open link ↗
• Class 10–12Join your school's science club or ask your Biology teacher about safe, supervised experiments, such as looking at yeast or mould under a microscope. Keep a notebook of what you observe and what you change.
• College or afterFind a free biology or microbiology course on NPTEL and finish one week of lectures. Then write a short summary of what you learned.Open link ↗

• Eligibility and admission rules differ widely between colleges. Read the current prospectus of each college you apply to, because the criteria change year to year.
• Some universities list PCB as the rule, but others accept Biotechnology in place of Biology. Some top colleges set cut-offs well above the minimum.
• No single licence is needed to work as a microbiologist. Employers usually ask for a B.Sc or M.Sc plus lab skills, and research posts usually need an M.Sc or PhD.
