These high-efficiency particulate air (HEPA) filters can remove up to 99.997% of particles >0.3mm in diameter and thus are acting as depth filters. Examples include: the sterilant, sterilization indicators, and services provided by contract sterilizers or contract laboratories. Further, it is capable of preventing the passage of both viable and nonviable particles and can thus be used for both the clarification and sterilization of liquids and gases. Cambridge. On average, the microorganisms may range from 10-2,000/m 3 while the suspended particles may be 20-100,00/ m 3. Pascalization is especially useful on acidic foods, such as yogurts and fruits, because spores which are pressure-tolerant dont have the ability to live in environments with low pH.

Factors affecting removal of M.O. The principle of pasteurization is the logarithmic reduction in the number of viable microbes so that they can no longer cause diseases. }~'{ no\/u\BrJYXXvcnz^z{ Wab.+?VZ1oN /G-)))***++m/^. Membrane filtration method is an assessment of water quality through the use of a special filter, i.e. Still, it can be applied to both moisture-sensitive and moisture-resistant products, for which dry (160180C) and moist (121134C) heat sterilization procedures are respectively used. Laboratory Manual in General Microbiology For Undergraduate Students. Steam Sterilization Really 2 different processes. Once they reach a maximum size, these cavities violently collapse, causing submicroscopic voids to form which induce the formation of high-energy hydraulic shock waves. Often filters are dried with compressed gas after sterilization and before use. Moist heat sterilization above 100C involves sterilization by steam under pressure. . Besides milk, other fluids and equipment like vaccines of non-sporing bacteria are also pasteurized at 60C for 1 hour in special water baths.

The term sterilization for pharmaceutical preparations, means the complete destruction of all living organisms and their spores or their complete removal from the preparation. The above PPT includes different methods of sterilization- Dry heat, Moist heat, Radiation and Chemical methods. The filter and housing are steam sterilized before product filtration, typically by steam-in-place (SIP) systems. Dry heat sterilization is used for the sterilization of materials which are difficult to sterilize by moist heat sterilization for several reasons. components of nutrient solutions which are heat -sensitive and would thus be denatured through the steam sterilization process normally used in industrial fermentation.
