MCB 3020L Lecture Notes - Lecture 44: Autoclave, Non-Ionizing Radiation, Bacteriostatic Agent
Document Summary
Filters composed of substances such as cellulose esters or plastic polymers that are 0. 1 mm thick and pores range in size as needed. Typically only have a bacteriostatic effect, but some bacteria will grow at a slower rate, but eventually will grow. High pressure applied to liquid suspension can alter the molecular structure of proteins and carbohydrates, but will leave endospores untouched unless combined with high temperatures as well. Absence of water that typically only have a bacteriostatic effect until water is reintroduced. High concentrations of salt and sugar have a similar affect on bacteria in that it deprives the cell of water. Gamma rays, x rays, or high-energy electron beam that have a wavelength of less than about 1 nm. Emitted by certain radioactive elements such as cobalt and electron beams are produced by accelerating electrons to high energies in special machines. Produced by machines in a manner similar to the production of electron beams.
