Antibiotic plate

For this experiment we wanted to test which antimicrobial agent our bacteria would be susceptible to.  We placed small samples of the antimicrobial agents onto a streaked plate of our bacteria. The next lab day we recorded the clear diameter of dead bacteria surrounding each microbial agent.


Diameter surrounding each


1.Penicillin : 1cm
2.Vancomycin: 1.2 cm
3.Novobiocin: 0 cm
4.Tetracyclic: 2 cm
5.Erythro: 1.9 cm
6.Chloramphenicol: 3 cm
7.Neomycin: 2 cm


By measuring the diameters we found that our bacteria was susceptible to Vancomycinb, Tetracyclic, Chloramphenicol, and Neomycin
