  1. Sterilization can be defined as any proces that effectively kills or eliminates transmissible agents (fungi, bacteria, viruses, prions).
  2. The air in the autoclave chamber is evacuated and filled with saturated steam.
  3. Thermal Death Time – a minimum time required to kill a suspension of organisms at a predetermined temperature in a specified environment.
  4. Encapsulation is method of physicall immobilization.
  5. The usual temperature for autoclave is 121 oC at exposure time of 15-20 minutes.
  6. UV light is generally used in irradiation of air in certain areas e.g. operating rooms and laboratories.
  7. We distinguish gravity method, vacuum and liquid method in kinds of autoclaves.
  8. Immobilization of biological material is related to attachment of a compund of interest to/within a support or matrix.
  9. Tyndallization may fail with spores of some anaerobes and thermophiles.
  10. The action of heat in sterilization will be due to induction of lethal events mediated through the action of water and oxygen.
  11. Autoclave is a pressurized device designed to heat aqueous solutions above their boiling point at normal atmospheric pressure to achieve sterilization.
  12. Filtration is physical method of sterilization.
  13. Main use of filtration is for heat labile substances like antibiotics, vitamins, amino acids, proteins and many gases.
  14. Heat sterilization can be performed with dry or moist heat.
  15. Free!
  16. Inspissation is the proces of thickening by dehydration in inspissator.
  17. Steam sterilizers autoclaves use pressurized steam heat to kill any microbial life that may be present on a contaminated load.
  18. Due to its reversibility and simplicity, the most favored method of immobilization is physical adsorption.
  19. Moist heat kills - microorganisms by denaturing and coagulating proteins.
  20. Steam at 100 oC contains 7x as much energy as water at 100 oC.
  21. DISINFECTANT – products used to kill microorganisms on inanimate objects or surfaces.
  22. Immobilization is a method for recovering enzymes.
  23. Both ethanol and isopropanol are widely used disinfectants, usually at concentration of about 70%.
  24. We can monitore autoclaves by heat sensitive chemicals.
  25. Filtration removes bacteria but viruses and some small bacteria may pass through.
  26. Advantages of heat sterilization are good penetrability and non-corosive nature.
