MICROBIOLOGY LABORATORY
The screening, isolation and characterization of microbes are critical for success in biotechnology discipline. Microbes provide with rich variety (including beneficial and pathogenic microbes) of structure, forms, and compounds that has been efficiently utilized in many functional domains. At TSBS, the Microbiology Laboratory caters to the biotechnology and applied microbiology courses. The following are the list of instruments in the microbiology facility-
