Hello! For those of you who saw the bacterial plates in person, you won’t believe these pictures! I think the bacteria was not given long enough to incubate. I think the zones of inhibition are clearly evident in the antimicrobial 1-6 plates. You can see what tables are represented in the pictures, and realize that the only unlabeled plates are from table 1.
So…for your quiz next week, November 5, you should expect to see a picture similar to the one you made for testing various substances and being able to determine which antibiotic/antiseptic/antimicrobial substance works the best or worst. For my ease, I would appreciate if one person from each table would comment to this post by stating where you took your samples for your 1-4 plates and what 1-5 substances were on your 1-6 plates. I know you have sent this info to me, but it will be easier if everyone can just look at the pictures and comments while in one place. Thanks much and I will see you Monday! Have a great weekend!
