Biotechnological emerged innovation in theproductive sector , the new biotechnology developments originate in research centers, generally located within universities.

The new biotechnologies can be grouped in four categories:
1-Techniques for culture cells and tissues.
2- Processes biotechnology, more about fermentation, including immobilization of enzyme.
3-  Techniques that apply to the selection of microbiology andcell culture and microorganisms.
4- Techniques for manipulation, modification and transfer of genetic material
Although the four groups complement between there, there is a important difference...
