Bioreactor has gone through three stages of development: bacterial genetic engineering, cell genetic engineering, and transgenic animal bioreactor. The emergence of transgenic animal bioreactors has attracted great attention because it overcomes the defects of the first two, that is, cell genetic engineering products are often not biologically active, and must undergo a series of modifications such as glycosylation and hydroxylation before they can become effective drugs, while cell genetic engineering limits large-scale production because the culture conditions of mammalian cells are quite demanding and the cost is too high.

In addition, the transgenic animal bioreactor also has the characteristics of high product quality and easy purification.

Generally, transgenic animals whose target fragments are expressed in organs or tissues are called animal bioreactors. Almost any living organ, tissue, or part of it can be domesticated into a bioreactor. From the perspective of production, the tissues or organs selected by the bioreactor should facilitate the acquisition of products, such as mammary glands, bladder, blood, etc., so the animal mammary gland bioreactor, animal blood bioreactor and animal bladder bioreactor have been developed.

Among them, the research on mammary gland bioreactors of transgenic animals is the most eye-catching.

Advantages of Animal Mammary Gland Bioreactors:

1.Stable product quality;

2.Low cost of product;

3.Short R&D cycle;

4.No pollution;

5.The economic benefits are significant.

Applications of Animal Mammary Bioreactors:

1.improve milk quality;

2.Production of medicinal proteins.

Problems with animal mammary gland bioreactors:

1.site integration of exogenous genes in animals;

2.tissue-specific issues of milk protein gene expression;

3.post-translational modification of the protein of interest;

4.isolation and purification of transgene expression products;

5.technical and methodological issues related to genetically modified organisms;

6.Ethical issues.

Bioreactor refers to a device system that uses enzymes or special functions of organisms (such as microorganisms, animal and plant cells, etc.) to carry out biochemical reactions in vitro.

Bioreactors are not the same as chemical reactors. Chemical reactors are energy-intensive processes that often require pressurization and heating from the entry of raw materials to the generation of products. Bioreactors, on the other hand, can be chemically synthesized at room temperature and pressure with the participation of enzymes and microorganisms.

Therefore, after the advent of bioreactors, they have attracted the attention of the chemical industry. Chemical engineering experts believe that as much of the chemical synthesis process should be done by living organisms. Designing the ideal bioreactor has become an important task for the modern biotechnology industry.

When designing a bioreactor, two points should be considered: one is to select enzymes with high specificity or suitable living cells as catalysts to minimize by-products and increase product yield; The second is to increase the concentration of the product as much as possible and reduce the cost.

Bioreactors were first used in the fermentation industry. The bioreactor used in the fermentation industry is actually a fermenter. The other is an enzyme reactor that uses immobilized enzymes or immobilized cells as catalysts.

The world's largest fermentation tank is 100 meters high, 7 meters in diameter and has a volume of 4,000 cubic meters. From afar, it looks like a spectacular round tower.

Definition 1: A general term for vessels used in biological reaction processes. Including enzyme reactors (free enzyme and fixed enzyme reactors), fixed cell reactors, various cell cultures, fermenters, and genetically modified plants and animals, etc.

It can be used to prepare or produce certain bioreaction products, and some can be used as biosensors.

Bioreactor: A bioreactor is a device system that uses the biological functions of enzymes or organisms (such as microorganisms) to carry out biochemical reactions in vitro, and is a kind of biological function simulation machine, such as fermenters, immobilized enzymes or immobilized cell reactors.

Bioreactors may sound unfamiliar, but the basic principles are fairly simple. The stomach is a complex bioreactor for the processing of food within the human body. Food is digested by various enzymes in the stomach and turned into nutrients that we can absorb.

Bioreactors in bioengineering are reaction devices designed to simulate the functions of living organisms in vitro and be used to produce or detect various chemicals. In other words, a bioreactor is a device system that uses the biological functions of enzymes or organisms (such as microorganisms) to carry out biochemical reactions in vitro, and is a kind of biological function simulation machine, such as fermenters, immobilized enzymes or immobilized cell reactors.

On the basis of the wide application of immobilized enzymes, it has been found that natural cells themselves have a multi-functional serial reaction system, and it is a shortcut to use enzymes or enzyme systems to immobilize cells by physical or chemical methods. An immobilized cell reactor is like a "promoter of vital activities". Immobilized cell technology began in the 70s, and its practical application has surpassed that of immobilized enzymes.

For example, the United States, Europe, and Japan have adopted the immobilized bacterial column bed process to produce high-fructose syrup on a large scale.

1.It can save the cost of building a plant and purchasing instruments and equipment.

2.Reduce complex production processes and environmental pollution.

3.The effect of the product is obvious.

Low cost, large yield, and can be prepared in large quantities

Divide, divide, I want to divide

Low cost, once and for all, you can get the desired product in large quantities.

It can make a large number of nutrients and medicines that are beneficial to the human body, including the improvement of military border defense, which is also of great help and benefit I'm also looking for this question, heheo(o, I asked our teacher.

A bioreactor is a reaction system that uses naturally occurring microorganisms or microorganisms with special degradation capabilities to inoculate into the liquid or solid phase. At present, the two most studied reactors are "elevator reactor" and "soil slurry reactor". The elevator reactor provides appropriate nutrients, carbon sources and oxygen through the flow of the aqueous phase, thereby degrading the pollutants in the soil.

Compared to solid-phase systems, bioreactors are able to effectively degrade contaminants in a shorter period of time. This bioreactor technology has been applied to the bioremediation of organically contaminated soils.

Chinese name. Bioreactors.

Foreign language name. bioreactor

Utilize enzymes or organisms.

Nature of medical devices.

A bioreactor is any manufacturing or engineering equipment that provides a biologically active environment. In one case, a bioreactor is a vessel that carries out a chemical process involving the production of biological or biochemically active substances from specific organisms.

This process can be performed either aerobically or anaerobically. These bioreactors are usually cylindrical in shape, ranging in volume from a few liters to several cubic meters, and are often made of stainless steel.

A bioreactor is a device system that uses the biological functions of enzymes or organisms (such as microorganisms) to carry out biochemical reactions in vitro. It has important applications in wine, pharmaceutical production, concentrated jam, fruit juice fermentation, and degradation of organic pollutants.
