Biotechnology

From Wikipedia, the free encyclopedia.

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine.

Of the many different definitions available, the one formulated by the UN Convention on Biological Diversity is one of the broadest:

Biotechnology is any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.

One section of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer, milk products, and skin). Naturally present bacteria are utilized by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and produce biological weapons.

There are also applications of biotechnology that do not use living organisms. Examples are DNA microarrays used in genetics and radioactive tracers used in medicine.

Modern biotechnology is often associated with the use of genetically altered microorganisms such as E. coli or yeast for the production of substances like insulin or antibiotics. It can also refer to transgenic animals or transgenic plants, such as Bt corn. Genetically altered mammalian cells, such as Chinese Hamster ovarian cells, are also widely used to manufacture pharmaceuticals. Another promising new biotechnology application is the development of plant-made pharmaceuticals.

Biotechnology is also commonly associated with breakthroughs in new medical therapies and diagnostic devices.

Sub-fields of biotechnology

There are a number of jargon terms for sub-fields of biotech.

Red biotechnology is biotechnology applied to medical processes. Some examples are the designing of organisms to produce antibiotics, and the engineering of genetic cures to diseases through genomic manipulation.

White biotechnology, also known as grey biotechnology, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. White biotechnology tends to consume less in resources that traditional processes when used to produce industrial goods.

Green biotechnology is biotechnology applied to agricultural processes. An example is the designing of an organism to grow under specific environmental conditions or in the presence (or absence) of certain agricultural chemicals. Green biotechnology tends to produce environmentally more friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby eliminating the need for external application of pesticides.

Bioinformatics is a an interdisciplinary field which addresses biological problems using computational techniques. The field is also often referred to as computational biology. It plays a key role in various areas like functional genomics, structural genomics, and proteomics amongst others, and forms a key component in biotechnology and pharmaceutical sector.

The term blue biotechnology has also been used to describe the marine and aquatic applications of biotechnology, but its use is relatively rare.

Biotechnology timeline

8000 BC Collecting of seeds for replanting. Evidence that Babylonians, Egyptians and Romans used selective breeding (artificial selection) practices to improve livestock.
6000 BC Brewing beer, fermenting wine, baking bread with help of yeast
4000 BC Chinese made yogurt and cheese with lactic-acid-producing bacteria
1500 Plant collecting around the world
1675 Microorganisms discovered (using first microscope)
1856 Gregor Mendel discovered the laws of inheritance
1919 Karl Ereky, a Hungarian engineer, first used the word biotechnology
1953 James D. Watson and Francis Crick describe the structure of DNA
1975 Method for producing monoclonal antibody developed by Kohler and Milstein
1980 Modern biotech is characterized by recombinant DNA technology. The prokaryote model, E. coli, is used to produce insulin and other medicine, in human form. (About 5% of diabetics are allergic to animal insulins available before)
1994 FDA approves of the first GM food from Calgene: "Flavr Savr" tomato
2000 Completion of the Human Genome Project

Ninth Day of Creation

Genetic engineering and drug design feature prominently in the work carried out at the fictional biotech company known as Immunological Technologies, which appears in the science thriller Ninth Day of Creation by Leonard Crane, published in 2000. Other notable biotechnology-related elements appearing in the book include a supposed solution to the protein folding problem, the creation of novel triple-helix based genetic medicines, and the reconstruction of the 1918 Spanish Flu from century-old fragments of viral RNA.
