Which sterilization kill spores?
A process called sterilization destroys spores and bacteria. It is done at high temperature and under high pressure. In health care settings, sterilization of instruments is usually done using a device called an autoclave.
Which method is used to sterilize room?
Table 59.2
| Methods of Sterilization | Example |
|---|---|
| High temperature | Steam, dry heat |
| Low temperature | Ethylene oxide gas, hydrogen peroxide, ozone, gas plasma, gaseous chlorine dioxide, ionizing radiation, pulsed light |
| Liquid chemicals | Chemical sterilants |
| Others | Filtration |
What are the methods to kill microbe and achieve sterility?
Sterilization can be achieved by applying the proper combinations of heat, chemicals, irradiation, high pressure, and filtration. Chemical agents that can eliminate or suppress microbial life are separated in different groups based on their use.
Which kind of sterilization procedure takes advantage of the size of microorganisms?
Which kind of sterilization procedure takes advantage of the size of microorganisms? Ultraviolet radiation is an effective means of sterilizing surfaces. If one left a “pasteurized” flask of broth for a long time at room temperature, it would stay sterile forever, at least in principle.
What is sterilization process?
Sterilization refers to any process that removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) After sterilization, an object is referred to as being sterile or aseptic.
What is the best method to kill microbes?
Autoclaving is the most reliable method of sterilization or killing bacteria and other microorganisms. It is used for all materials that contain water, and are permeable or wettable and not liable to be damaged by the process. Autoclaving provides moist heat at a temperature higher than 1000C.
How can we kill microbes?
High heat combined with high moisture is one of the most effective methods of killing microorganisms.
- Parameters that Influence Heat (Temperature) Sterilization:
- Moist Heat Sterilization:
- Dry Heat Sterilization:
- (i) Filtration of Biological Fluids (Biological Filters):
- (ii) Filtration of Air:
- (i) Ionizing Radiation:
How do we control microorganisms?
Microorganisms are controlled by means of physical agents and chemical agents. Physical agents include such methods of control as high or low temperature, desiccation, osmotic pressure, radiation, and filtration.
