B.Sc Microbiology

If you are thinking about a high-paying salary, the major difference is that biotechnology is a broad field. In this course, you will study about a lot of different subsets of biotechnology, that are bioinformatics, plant biology, animal biology, biochemistry, genetics and heredity, etc.
Microbiology is (somewhat) a type of specialisation. If you do choose B.Sc Microbiology you are confined to a type of field only for your Master's degree, but don't take my word for it. As I said earlier, different universities have a different syllabus and teaching styles too.

You need to have at least 60% aggregate in class 12th with physics, chemistry and biology as the main subjects.

B.Sc in Microbiology pass outs has a great career scope abroad. They can work in a lot of job profiles like
Bacteriologists
Industrial Microbiologists
Medical Microbiologists
Biotechnologist
Biomedical Scientist
Cell Biologists
Geneticists
Mycologists
Protozoologists
Biochemist
Immunologists
Parasitologists
Virologists
Environmental Microbiologists
Food Microbiologists
Various organisations abroad demand experts in this field. The salary packages basically depend on the job profile and the chosen firm.

B.Sc in biotechnology would be a better choice since microbiology is a part of biotechnology.
Good luck.
