What is biochemical engineering? Please briefly describe the development history of biochemical engineering.

Biochemical engineering is the engineering application of biochemical reaction, which mainly includes metabolic engineering, fermentation engineering and biochemical sensors. Biochemical engineering and biomedical engineering are the original concepts of bioengineering. In 2 1 century, gene recombination, fermentation engineering, cell engineering and biochemical engineering were combined to form a systematic bioengineering. The book is divided into ten chapters, which mainly introduces culture medium sterilization, air sterilization, aeration and stirring, comparison and amplification of fermentors, immobilized enzymes and cells, typical fermentation process dynamics and models, online measurement and instrumentation of fermentation process parameters, quality and energy balance of microbial biochemical reaction process, computer online control of fermentation process and downstream technology of fermentation engineering.

The development of biochemical engineering can be divided into three periods: ① the period of traditional biotechnology; ② the formation and development period of modern bioengineering; ③ Modern bioengineering period.
