What Is Asepsis?
It means no live bacteria, and it is an important concept in biotechnology. Only under the premise that the culture medium, fermentation equipment, etc. are sterile, can the purebred culture be realized after the microorganisms are inoculated, and finally the desired products can be obtained. The method of preventing microorganisms from entering the body or object is called aseptic operation or aseptic technique. Microbiological experiments, surgical procedures, dressing changes, and injections must be carried out in strict accordance with aseptic procedures.
- The so-called sterility of an environment means that everything in the environment has
- 1.Superheated steam sterilization method
- The advantage of this sterilization method is that the iron can can obtain a higher temperature under pressure, but the microorganisms have greater thermal resistance in superheated steam than in saturated steam, so the sterilization temperature requirements are higher.
- 2. Dry hot air sterilization method
- Like superheated steam, the use of dry hot air has its advantages and disadvantages, and is mostly used in aseptic packaging systems for compound tanks. This method has not been used for the aseptic production of low-acid foods, but this aseptic equipment has been used for the production of juice drinks.
- 3. Hydrogen peroxide sterilization method
- Utilize the sterilization effect of hydrogen peroxide, and then use other thermal methods to achieve the purpose of sterilization. [1]
