    • Define and distinguish pH groups - acidophile, neutrophile, alkaliphile - and classify bacteria by their pH preferences?
    • Define the terms used to control microbial growth - antiseptic, disinfectant, sterilant, sanitizer - and the difference between -cidal (killing) and -static (inhibiting) agents?
    • Define zone of inhibition and compare the effectiveness of chemical agents in a disk-diffusion experiment?
    • Explain the Kirby-Bauer sensitivity test, including the role of Mueller-Hinton agar and how the test is performed?
