What are the recombinant bacteria?

Recombinant bacteria are bacteria that have undergone genetic engineering. This means that their DNA has been changed by introducing a new DNA. Such bacteria are of immense value in biological research and for industrial and environmental use. It can be a plasmide or virus. Plasmid has a type of optional marker, so the cells will continue to produce it. This is often resistance to antibiotics. It is also possible to introduce a gene directly into the DNA bacteria. The laboratory rat of the bacterial world is Escherichia coli , commonly found in our intestines. Many stations e coli are available for cloning experiments.

There are many cloning kits that facilitate the high level of protein expression produced by the cloned gene in e coli . In basic research, such techniques help provide enough material to study the function and properties of the gene product. Enabled the production of materials that are of greatEven difficult to isolate from natural resources. Insulating compounds from humans also risk spreading diseases. In this way, many proteins of medical importance were produced. Examples are insulin, human growth hormone and erythropoetin anti -nine.

Many other types of bacteria are able to be changed genetically. This includes those that can live in more extreme conditions such as dirty waste water. The process of production of chemicals or degrading is often performed by several different chemical steps. Scientists were able to design some of the recombinant bacteria with genes for the whole path for biosynthesis or biodegradation of compounds.

genetically changed bacteria are looking for use in Biorediation . This is the practice of using organisms to treat human pollution. For decades bacteria and fungi have been used to treat waste water and decontaminate water and soils infunded by organic pollutionsjoining substances. With the advent of genetic engineering, however, it is possible to design recombinant bacteria for decomposing pollutants under the conditions that unchanged microorganisms can be considered unfavorable.

bacteria are particularly furious when receiving toxic metals. Treatment of contaminated soil and solid waste is usually performed in a large tank known as bioreactor . This is a way to contain recombinant bacteria, so they do not escape into the environment. It also makes it easier to optimize the environmental conditions for those that prefer growth. Also, new strains can be created bacteria for decomposing compounds, which were previously very resistant to degradation.
