Analogy amplification of fermentation tank
Firstly, it is necessary to identify the various parameters that characterize this system, assemble them into several dimensionless numbers with certain physical meanings, and establish functional equations between them. Then, using experimental methods, the constants and exponents contained in this functional equation can be obtained in the experimental equipment. Under certain conditions, this relationship equation can be used as a basis for analogy amplification.

Fermentation technology: comprehensive analysis and prevention measures of contamination
To improve the level of production technology, strengthen the management of the production process, grasp the various links that are prone to bacterial contamination, and prevent the occurrence of fermentation bacterial contamination as much as possible; And once bacterial contamination occurs, the cause of the contamination should be identified as soon as possible, and corresponding effective measures should be taken to minimize the losses caused by fermentation bacterial contamination.

Key points for attention of fermentation equipment
Prepare the culture medium in a fermentation tank, heat it directly with saturated steam to reach the predetermined sterilization temperature and maintain it at that temperature for a period of time, then cool it down to the fermentation temperature. This sterilization process is called medium tank sterilization or medium batch sterilization (sterilization).

Animal vaccine cultivation and fermentation production
The in vitro culture of animal cells has always been a research field that scientists attach great importance to. Nearly a century after American Harrison successfully cultured the neural tissue of tadpoles in vitro in 1907, animal cell culture played a very important role in animal virus research and vaccine production. Through large-scale cultivation of animal cells, many valuable biological substances have been obtained, such as vaccines, diagnostic reagents, interferons, and monoclonal antibodies, providing favorable guarantees for human health. The concept of "tissue engineering" was proposed in the late 1980s, and the three-dimensional culture of animal cells became an important research topic
