Chapter 11, Episode 49

Additional chemical control methods include alcohols, oxidizing agents, surfactants, quats, heavy metals, aldehydes, gaseous sterilants, and essential oils, each with distinct mechanisms and applications. Alcohols and phenolic-type compounds disrupt membranes and proteins, oxidizing agents damage cells through reactive oxygen species, and surfactants remove microbes through mechanical action. Heavy metals interfere with proteins but can accumulate and cause toxicity, while aldehydes and ethylene oxide act as powerful sterilants. Overall, chemical control depends on choosing the right agent based on microbial resistance, toxicity, and the balance between killing microbes and inhibiting their growth.
