I need some help. Our teacher requires us to do 2 confirmatory tests to confirm our unknown once we think we know what it is. I have had a lot of problems with all of my tests and she thinks mine may be contaminated. She pretty much gave me the answer to what mine is and even gave me other students cultures that had the same unknown as me (since she thinks mine are contaminated) and she wants me to run 2 confirmatory tests but I can't find any to do. I have done:
Growth at 40 degrees
Fluorescents test (where you hold it under uv light and see if it glows) But the last 3 are not coming out right please tell me what other tests I can do. Thanks!
