Explanation:

The diffusion procedure used to determine the minimum inhibitory concentration (MIC) for a microbe, involving antibiotic - containing discs or strips (like the strip shown in the image) to test antimicrobial susceptibility, is the Etest (epsilometer test). This test uses a gradient of the antimicrobial agent on a strip, and the point where growth inhibition starts indicates the MIC.
