- what is "How Regulation Stymies Medical Research of Controlled Substances" by Alivia Kaylor?This diagram shows the filter paper method used to evaluate the inhibitory effect of chemical agents, heavy metals, and antibiotics on bacterial growth. A culture of a test bacterium is spread uniformly over the surface of an agar plate. Small filter paper discs containing the material to be tested are then placed on the surface of the medium. A disc that has been soaked in sterile distilled water is sometimes added as a control. After incubation, a lawn (film of growth) will cover the plate, but a clear zone will surround those discs that contain an inhibitory compound. The size of the zone reflects several factors, one of which is the effectiveness of the inhibitory agent. What are two other factors that might affect the size of the zone of inhibition? What is the purpose of the control disc? If a clear area were apparent around the control disc, how would you interpret the observation?I missed a couple of my labs due to covid and am struggling to teach myself how to do serial dilution, dilution, dilution factors, and colony forming units per ml of original stock. I thought I was understanding everything until it was time for me to take the practice quiz and I realized that I understood nothing.
