Dear Blog and Blog Readers,
We checked the final agar plate filled with bacteria grown from a swab of a sink handle to see what disinfectant was most effective. Soap, lysol, lysol wipes, and hand sanitizer were tested.
Lysol wipes!
Lysol wipes actually inhibited the most bacterial growth, interestingly enough! So the next time you're going to to go to clean the bathroom, be sure you ditch the spray and soap and use lysol wipes!

The whole plate.
The hand sanitizer did not kill very much bacteria at all!
This was mislabeled wipe--it's actually spray--which killed some bacteria.
This was mislabeled spray--it's actually the wipe-- which inhibited the growth of a lot of bacteria!
The soap inhibited the growth of some bacteria.
And the winner is.....Lysol wipes!

We also performed the last test needed to discover our bacteria...antibiotic testing! We inoculated a spread plate with bacteria S and separated it into 5 sections. We then placed different antibiotic disks on each section and placed it in the 25 degree incubator. Next class we will see what kills our bacteria!
Here is the list of antibiotics we could choose from to test with.
We decided to use novobiocin, erythromycin, an aminoglycoside which was neomycin, tetracycline, and penicillin.

Max placing the antibiotic circles on the plate.
The final spread plate!
Check back next time to see which antibiotic was most effective!
