See both of the subjects you have mentioned have amazing scope in research as well as in industrial sector.

Bsc Microbiology is all about the study of microbial organisms and to infer information from various characteristics and finding out there effects in ecosystem.

Advanced Zoology and Biotechnology is a applied field concerned about the sciences involving evolution, genetics, anatomy and related fields.

Thus both of the field have there certainties in industry. Pharma companies appoints a lot of MSc Microbiologist for the sales and marketing as well as R&D purposes. The Biotechnologist also have a good scope in the industry although its always preferred that a BTech Biotechnologist for industrial purpose.

So if you ask my opinion then I would say BSc Microbiology will be a better option than the other course because BSc Microbiology have a elongated area of work field which isn't hampered by anyother branch unlike Biotechnology.

**Your career is the most important. Thus I would recommend you to go for it after you conduct an research by yourself and infer that you agree to my logics. If you don't agree then go for what ever will be the best for you.
