Biotechnology: Broad definition
FDA's working definition of biotechnology is “the application of biological systems and organisms to technical and industrial processes”.
This definition takes : • Both the "old" and "new" science age-old techniques and most advanced uses of
recombinant DNA technology.
• Many applications…

Stages of Biotechnology
Ancient Biotechnology
• Early history as related to food and shelter, including domestication
Classical Biotechnology
• Built on ancient biotechnology
• Fermentation promoted food production & Medicine
Modern Biotechnology
• Manipulates genetic information in organism
• Genetic engineering
• And….

Stages of Biotechnology
Ancient Biotechnology (Pre 1800)
Long history of fermented foods since people began to settle (9000 BC) • Often discovered by accident! • Improved flavor and texture • Deliberate contamination with bacteria or fungi
(molds)
Fermented foods and beverages

Stages of Biotechnology
Classical Biotechnology
• Different types of beverages (beer, wine, cider…) • Vinegar, Glycerol, Acetone, Butanol • Lactic acid, Citric acid • Antibiotics
Industrial exploitation of fermentation process for production of huge numbers of products
(From 1800 to the middle of 20th century)

Stages of Biotechnology
Classical biotechnology
Substrate + Microbial Enzyme Product Example:
• Cholesterol Steroids (cortisone, estrogen…)
Chemical transformations to produce therapeutic products

22
Stages of Biotechnology
• Amino acids to improve food taste, quality or preservation
• Enzymes (cellulase, collagenase, diastase, glucose isomerase, invertase, lipase, pectinase, protease)
• Vitamins,
• Pigments
Microbial synthesis of commercially valuable products

Stages of Biotechnology
Modern Biotechnology
The Second World War is considered a major crisis that has led to scientific discoveries : very crucial discoveries were reported, which paved the path for modern biotechnology and to its current status. In 1953, JD Watson and FHC Crick for the first time cleared the mysteries around the DNA as a genetic material, by giving a structural model of DNA known as “Double Helix Model of DNA”.

Red biotechnology/Medicine
All those biotechnology uses connected to medicine…
• producing vaccines and antibiotics,
• developing new drugs,
• molecular diagnostics techniques,
• regenerative therapies and the development of genetic engineering to cure diseases through genetic manipulation.
Examples : cell therapy and regenerative medicine, gene therapy and medicines based on biological molecules such as therapeutic antibodies.

White biotechnology /Industry
All the biotechnology uses related to industrial processes design low resource-consuming processes and products, making them more energy efficient and less polluting than traditional ones.
Examples : the use of microorganisms in chemicals production, the design and production of new materials for daily use (plastics, textiles ...), the development of new sustainable energy sources such as biofuels.

Grey biotechnology / Environment
All applications of biotechnology directly related to the environment. These applications can be split up into two main branches: biodiversity maintenance and contaminants removal.
Biodiversity maintenance: analysis of populations and species, comparison/classification and cloning to preserve species and genome storage technologies.
contaminants removal : uses microorganisms and plants to isolate and dispose of different substances such as heavy metals and hydrocarbons…
