What purpose does the nutrient agar plate serve? The nutrient agar plate will serve as a comparison for growth for quality on the MSA plate. Since the MSA plate will favor the growth of gram-positive cocci, you'll be able to â¦ see the growth of both gram-negative and gram-positive on the nutrient agar plate. What was the purpose of incubating unopened plates for microbiology? to determine and test its growth rate at room temperature and body temperature as a control plate. Edit
On each dish we added the bacteria Bacillus subtillus and three antibiotic discs: penicillin, streptomycin, and tetracycline. We also added a blank disc to act as the control. The purpose of the control is two-fold. First, it shows us what normal growth of bacteria looks like. Second, it shows us that the antibiotics, and not the paper, are affecting the bacteria. We left the petri dishes in an incubator over night so they could grow.
