Internal connection of Bioengineering

Date of release:2016-08-04 Author: Click:

        Bioengineering is already an indispensable part of our lives. As a new era of engineering technology which has a significant impact on our lives, biotechnology has an important impact on our lives. Here is a brief introduction to the relationship between components of biotechnology engineering. So that we can better understand biotechnology.

Fermentation engineering
Fermentation engineering refers to the use of engineering and technical means, the use of biological, mainly some functions of microorganisms, for the production of useful biological products for mankind, or directly with microorganisms to participate in the control of some local production process of a technology. It is well known that the fermentation of beer, wine, industrial alcohol, cheese and yoghurt by lactic acid bacteria, large-scale production of penicillin by fungi are examples of this. With the progress of science and technology, fermentation technology has made great progress, and has entered the stage of modern fermentation engineering which can control and transform microorganisms artificially and make them human products. As an important part of modern biotechnology, modern fermentation engineering has broad prospects. For example, the use of DNA recombination technology to purposefully transform the original strains and increase their production; the use of microbial fermentation to produce drugs, such as human insulin, interferon and growth hormone.
Two. Cell engineering
Cell engineering refers to the application of cell biology and molecular biology methods, through some engineering means, in the overall level of the cell or organelle level, according to people's wishes to change the genetic material in the cell or obtain a comprehensive technical science of cell products.
Cell engineering involves a wide range of fields, such as cell fusion technology, cell disassembly technology, chromosome introduction technology, gene transfer technology, embryo transfer technology and cell tissue culture technology.
1. Plant Tissue Culture: Under artificial operation, the organs, tissues or cells of plants are removed from the plant body, and appropriate nutrients are supplied in certain containers, so that they can be differentiated, developed and grown. Plant cells or organs used in tissue culture are called explants. After the explants divide again on the artificial medium, a group of undifferentiated cells with the same morphology, structure or similarity are called callus. The callus cells begin to differentiate under certain external factors, and eventually develop into a complete plant. The basic principle of this technology is the totipotency of plant cells. This technology is currently mainly used for crop improvement and production of useful physiological substances. Using plant tissue culture technology, tens of thousands or even hundreds of thousands of seedlings can be cultivated in one year with a small piece of plant tissue, which is superior to introducing fine varieties or rare varieties which are difficult to reproduce. Stem tips of phases are usually not infected by viruses, and virus-free plants can be obtained by tissue culture of stems.
2. cloned animals: generally refers to the formation of animal offspring by asexual reproduction. In 1997, British biologists successfully cloned a young ewe, Dolly sheep, from somatic cells of sheep for the first time. Cloning refers to asexual reproductive lines, specifically, from a common ancestor, through the method of asexual reproduction produced a group of genetic characteristics of the same DNA molecules, cells or individuals. Cloning can also refer to the process of asexual reproduction.
3. Monoclonal antibody: the immune B lymphocytes and myeloma cells fused together to form hybridoma cells. Such cells can prolong asexual reproduction like tumor cells and secrete antibodies like B lymphocytes. And because this antibody can be produced by a single clonal cell line, it is also known as monoclonal antibody. This technology has been widely applied in clinic.
Three. Genetic engineering
Genetic engineering, also known as genetic engineering, is the main technology of biotechnology. Genetic engineering refers to the technology that according to human desire, the genetic material of different organisms is artificially cut in vitro and transformed into cells after vector recombination to amplify and express the required protein. Genetic engineering can break the boundaries of species, alter bioheritability at the genetic level, and provide useful products and services to humans through engineering.
