I need help with the discussion and conclusion. This is the correct result from the experiment and correct format for the lab report.
Objective
Antibiotic disc test (Perform antibiotics test assay)
Introduction
The purpose of this experiment is to learn how to test the susceptibility of microorganisms to various antibiotics. Antibiotic is a chemical produced by a fungus or bacterium that has the potential to limit the growth of another bacterium.
Material and Methods
The description is in the laboratory manual. Test 1 using the aseptic technique to paint the entire surface of a sterile agar plate with E. coli and to covers all the areas then place four different antibiotics disc onto the marked surface with their proper name onto it.
Results
Table 1: Antibiotic inhibition zone results for E. coli
Diameter â Disc/2 = Radius (r)
Disc = 6mm/10 = 0.6 cm.
Bacterium: E. coli
Antibiotic used
Inhibition zone size (cm)
Penicillin 10 mg/1
0
Ampicillin
3.8 â 0.6/2 = 1.6
Penicillin 100 mg/1
1.70 â 0.6/2 = 0.55
Cefoxitin
4.20 â 0.6/2 = 1.8
