Cell culture technology has been widely used in many fields such as biopharmaceutical, genetic engineering, tissue engineering, food industry and environmental science. Animal cell culture is widely used for vaccine production, antibody preparation and protein expression, while plant cell culture is mainly used for plant active ingredient extraction, genetic modification and biosynthesis. In order to optimize the culture conditions and increase the cell growth and product yield, the selection and design of bioreactor are very important. In this paper, the culture process of animal and plant cells will be described in detail and their special requirements for bioreactors will be discussed.

With the continuous development of biotechnology, plant cell bioreactor has become an important tool for the production of high value-added biological products such as medicinal proteins, polysaccharides and secondary metabolites. The design of plant cell bioreactor directly affects its yield, stability and production cost, so it is very important to optimize its composition and design specification. In this paper, the key components of plant cell bioreactors and their design specifications will be discussed in detail.

Plant nutrition is a crucial link in agricultural production, affecting the growth, yield and quality of crops. In recent years, biological fermentation technology has been widely used in the field of plant nutrition, using the metabolism of microorganisms to decompose organic matter and convert it into nutrients that are more easily absorbed by plants, improve the utilization rate of fertilizer and improve the soil environment. The biological fermentation process of plant nutrients, its application in agriculture and the specific requirements for fermenters were discussed in this study.

Biological fermentation system is widely used in pharmaceutical, food, bioenergy, environmental protection and other fields, its core is the use of microorganisms or cells under well-controlled conditions for growth, metabolism and product synthesis. An efficient and stable fermentation system requires several key components to work together to ensure an optimal culture environment and ultimately a high yield, high quality target product. This article will introduce the important components of the biological fermentation system and discuss the key matters that need attention during operation.
