Also known as biotechnology or biotechnology. Applying the principles of biology and engineering, aiming at the unique functions of biomaterials and organisms, the comprehensive science and technology of new biological varieties with specific characteristics are established directionally. Bioengineering was developed on the basis of molecular biology and cell biology in the early 1970s, including genetic engineering, cell engineering, enzyme engineering and fermentation engineering. They are interrelated, among which genetic engineering is the foundation. Only by transforming organisms through genetic engineering can we produce more and better biological products according to human wishes. The results of genetic engineering can only be transformed into products through projects such as fermentation.

Medical bioengineering can produce a large number of cheap drugs to prevent and treat human diseases, such as insulin, interferon, growth hormone, hepatitis B vaccine and so on. Bioengineering is also widely used in food and light industry. During the period of 1983, the annual output of high fructose syrup used to make drinks in the United States reached 6 million tons, thus reducing the consumption of sucrose by half. The use of bioengineering technology has greatly changed the breeding work, such as transferring disease-resistant genes into tobacco and cultivating new tobacco varieties to prevent pests; Some achievements have also been made by transferring the nitrogen-fixing genes of rhizobia from lower organisms into the cells of higher crops, so that they can produce nitrogen fertilizer by themselves. At present, all countries in the world attach great importance to bioengineering, and China also lists bioengineering as one of the key scientific research projects. The research of bioengineering will have a great impact on human production and lifestyle.

Bioengineering, also known as biotechnology or biotechnology, is a technology that uses biology to carry out human medicine, environment and agricultural food. Early biotechnology can be traced back to ancient times, when Egyptians used yeast to make wine. Later, it includes the traditional use of microbial fermentation technology for food fermentation, or fermentation to produce antibiotics. Are examples of using biotechnology. Modern biotechnology, since the discovery of DNA structure in 1950, molecular biology has developed rapidly, which has revolutionized traditional biotechnology. For example, insulin, insulin, insulin is cloned into E.coli by gene cloning technology. Opened the industrial value of modern biotechnology.
