MCB 3020L Chapter Notes - Chapter 16: Reaction Rate, Ideal Gas Law
Document Summary
Sterilization: the complete elimination of vegetative bacterial cells. Ionizing radiation (x rays or gamma rays: are both commonly used to sterilize items such as disposable medical tools and equipment, as the radiation pass through the microbial molecules, they force electrons out of their shells, creating ions. These ions quickly combine (mostly with cellular water) and free radicals are generated. Free radicals can affect cell metabolism and physiology. Ionizing radiation does not have a direct effect on nucleic acids (such as dna or. Rna: advantages: the items being sterilized remain at normal temperatures and containers are able to remain completely sealed throughout the sterilization process due to the penetrating abilities of the ionizing radiation passing through them. Heat: probably the most common form of sterilization. Pressure is the key because of the ideal gas law- as pressure increases, so will temperature.
