Choice of sterilization method:
Continuous sterilization: It is suitable for large-scale production, which can ensure the continuous supply and sterilization efficiency of the feed liquid, but requires a large equipment investment.
Filtration sterilization: It is suitable for heat-sensitive materials, which can avoid material denaturation or activity loss that may be caused by heat treatment.
Batch sterilization: suitable for small-scale or intermittent feeding, the equipment is simple, but may not be as thorough as continuous sterilization.
Sterilization of ancillary equipment and piping: In addition to the feed, the fermenter and its ancillary equipment and piping also need to be sterilized to avoid becoming a source of microbial contamination. Commonly used methods include steam sterilization and chemical sterilization.
Fermentation Room Temperature Sterilization Technology: Provides a new sterilization solution, including:
Fermentation bacteriostatic solution: It reduces the growth of environmental bacteria by reducing the amount of miscellaneous bacteria, which helps to solve the problem of filtration membrane sterilization.
Sterilization in fermentation workshop: Intelligent technology is used to realize normal temperature sterilization in a large-scale fermentation workshop where man and machine coexist, avoiding the inconvenience of high-temperature and high-pressure sterilization.
Ventilation system sterilization: including air compressor pipeline sterilization technology and VHP (Vaporized Hydrogen Peroxide) pipeline sterilization technology, which has the characteristics of almost non-corrosive and rapid sterilization.
The choice of sterilization technology should be determined according to the specific fermentation process, material characteristics and production scale.
At the same time, as technology evolves, new sterilization methods may offer solutions that are more efficient, more economical, or better suited to specific applications.
In practice, the cost-effectiveness, ease of operation, and environmental impact of sterilization methods also need to be considered.
