Minor in Microbiology

Students on Summer 2022, Fall 2022, or Spring 2023 requirements MICRMIN

The Minor in Microbiology will allow students to demonstrate that they have specialized in Microbiology as a sub-discipline through taking several core Microbiology courses. It has been specifically designed to benefit students who wish to explore their appreciation for the importance and fascinating lifestyles of microbes in conjunction with majors outside of Biology and Microbiology.


The minor requires at least 17 credit hours, including the requirements listed below.
  1. Principles of Chemistry and Biochemistry. One (1) course:
    • CHEM-C 105 Principles of Chemistry I
    • CHEM-C 117 Principles of Chemistry and Biochemistry I
    • CHEM-H 117 Principles of Chemistry and Biochemistry I, Honors
    • CHEM-J 117 Principles of Chemistry and Biochemistry for Science Majors
  2. Molecular Biology. One (1) course:
    • BIOL-L 211 Molecular Biology
    • BIOL-S 211 Molecular Biology, Honors
  3. Microbiology. One (1) course:
    • BIOL-M 250 Microbiology
    • BIOL-M 380 Microbiology of Infectious Disease
  4. Microbiology Lab. One (1) course:
    • BIOL-M 315 Microbiology Laboratory
    • BIOL-M 316 Molecular Microbiology Laboratory
    • BIOL-M 435 Viral Tissue Culture Laboratory
    • BIOL-M 445 Medical Microbiology: Laboratory

    • BIOL-X 150 ASURE Biology Research Lab 1 (approved topics only; see academic advisor)
    • BIOT-X 150 ASURE Biotechnology Research Lab 1
  5. Electives. Two (2) courses:
    • Additional 400-level courses from the Microbiology Lab List above.
    • BIOL-L 472 Microbiomes: Host and Environmental Health
    • BIOL-M 350 Microbial Physiology and Biochemistry
    • BIOL-M 360 Microbial Physiology Laboratory
    • BIOL-M 430 Virology Lecture
    • BIOL-M 440 Medical Microbiology: Lecture
    • BIOL-M 460 Microbial Evolution

    • BIOT-X 325 ASURE Biotechnology Research Lab 2
  6. Minor GPA, Hours, and Minimum Grade Requirements.
    1. Minor GPA. A GPA of at least 2.000 for all courses taken in the minor—including those where a grade lower than C- is earned—is required.
    2. Minor Minimum Grade. Except for the GPA requirement, a grade of C- or higher is required for a course to count toward a requirement in the minor.
    3. Minor Upper Division Credit Hours. At least 9 credit hours in the minor must be completed at the 300–499 level.
    4. Minor Residency. At least 9 credit hours in the minor must be completed in courses taken through the Indiana University Bloomington campus or an IU-administered or IU co-sponsored Overseas Study program.

Minor Area Courses

Unless otherwise noted below, the following courses are considered in the academic program and will count toward academic program requirements as appropriate:

  • Any course at the 100–499 level with the BIOL subject area prefix—as well as any other subject areas that are deemed functionally equivalent
  • Any course contained on the course lists for the academic program requirements at the time the course is taken—as well as any other courses that are deemed functionally equivalent—except for those listed only under Addenda Requirements
  • Any course directed to a non-Addenda requirement through an approved exception

This program of study cannot be combined with the following:

  • Bachelor of Arts in Biology (BIOLBA)
  • Bachelor of Arts in Microbiology (MICRBA)
  • Bachelor of Science in Biology (BIOLBS)
  • Bachelor of Science in Microbiology (MICRBS)
  • Minor in Biology (BIOLMIN)
  • [Name unavailable] (BIOLTSBA)
  • [Name unavailable] (BIOLTSBS)

Exceptions to and substitutions for minor requirements may be made with the approval of the unit's Director of Undergraduate Studies, subject to final approval by the College of Arts and Sciences.
