These values can cover a wide range, which is important for the preservation of food and to microorganisms' survival in the stomach. The act of handwashing is an example of degerming, in which microbial numbers are significantly reduced by gently scrubbing living tissue, most commonly skin, with a mild chemical (e.g., soap) to avoid the transmission of pathogenic microbes. Time it takes to kill a microbial population is proportional to number of microbes. Our mission is to improve educational access and learning for everyone.
