Yes, if you choose to major in microbiology, you can also become a lecturer in Zoology or Botany. To qualify for lectureships, you must first complete a master's degree in microbiology before applying for exams like the CSIR NET. You can be chosen for a lectureship and a Junior Research Fellowship through the CSIR NET Exam, which is administered by the NTA (National Testing Agency). Only candidates from the Science stream are eligible to take this exam. The subjects covered by this exam include:
Natural Science
Molecular Science
Life Science Mathematical Science
Planetary Science
You must submit a CSIR NET Life Sciences application because you are studying microbiology. The administrators will issue you a Certificate once you pass the test, which you can use to apply for assistant professor positions at various colleges and universities.
