Developing Antibiotic Eveloping Antibiotic Resistance in Soil Bacteria

The purpose of this experiment was to create an antibiotic resistance in soil bacteria, and to determine to which antibiotic bacteria would develop the greatest resistance. Antibiotics used were Penicillin, Amoxicillin, and Streptomycin. Soil bacteria were collected and exposed to each of the three antibiotics and allowed to incubate for 48 hours. Then the strongest bacteria (those around a zone of inhibition surrounding the antibiotic disc) were exposed to the antibiotics again. Soil bacteria developed the greatest resistance to Streptomycin, but a resistance to Penicillin and Amoxicillin was also created.
