Not surprisingly, they hold a range of opinions on which approaches and developments in biology are the most important and on how new technologies will affect our lives.
History of biotechnology Although not normally what first comes to mind, many forms of human-derived agriculture clearly fit the broad definition of "'utilizing a biotechnological system to make products". Indeed, the cultivation of plants may be viewed as the earliest biotechnological enterprise.
Agriculture has been theorized to have become the dominant way of producing food since the Neolithic Revolution. Through early biotechnology, the earliest farmers selected and bred the best suited crops, having the highest yields, to produce enough food to support a growing population.
As crops and fields became increasingly large and difficult to maintain, it was discovered that specific organisms and their by-products could effectively fertilizerestore nitrogenand control pests.
Throughout the history of agriculture, farmers have inadvertently altered the genetics of their crops through introducing them to new environments and breeding them with other plants — one of the first forms of biotechnology. These processes also were included in early fermentation of beer.
In brewingmalted grains containing enzymes convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains broke down into alcohols, such as ethanol.
Later, other cultures produced the process of lactic acid fermentationwhich produced other preserved foods, such as soy sauce. Fermentation was also used in this time period to produce leavened bread.
Biotechnology in medicine the process of fermentation was not fully understood until Louis Pasteur 's work init is still the first use of biotechnology to convert a food source into Biotechnology in medicine form.
Before the time of Charles Darwin 's work and life, animal and plant scientists had already used selective breeding. Darwin added to that body of work with his scientific observations about the ability of science to change species.
These accounts contributed to Darwin's theory of natural selection. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops. InChaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicumto produce acetonewhich the United Kingdom desperately needed to manufacture explosives during World War I.
InAlexander Fleming discovered the mold Penicillium.
His work led to the purification of the antibiotic compound formed by the mold by Howard Florey, Ernst Boris Chain and Norman Heatley — to form what we today know as penicillin.
Inpenicillin became available for medicinal use to treat bacterial infections in humans. Cohen Stanford significantly advanced the new technology in by transferring genetic material into a bacterium, such that the imported material would be reproduced.
The commercial viability of a biotechnology industry was significantly expanded on June 16,when the United States Supreme Court ruled that a genetically modified microorganism could be patented in the case of Diamond v.
Chakrabarty's work did not involve gene manipulation but rather the transfer of entire organelles between strains of the Pseudomonas bacterium. Revenue in the industry is expected to grow by This section needs to be updated.
Please update this article to reflect recent events or newly available information. October Another factor influencing the biotechnology sector's success is improved intellectual property rights legislation—and enforcement—worldwide, as well as strengthened demand for medical and pharmaceutical products to cope with an ageing, and ailing, U.
The biotechnology sector has allowed the U. By increasing farm productivity, biotechnology boosts biofuel production. For example, one application of biotechnology is the directed use of organisms for the manufacture of organic products examples include beer and milk products. Another example is using naturally present bacteria by the mining industry in bioleaching.
Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities bioremediationand also to produce biological weapons. A series of derived terms have been coined to identify several branches of biotechnology, for example: Bioinformatics also called "gold biotechnology is an interdisciplinary field that addresses biological problems using computational techniques, and makes the rapid organization as well as analysis of biological data possible.
The field may also be referred to as computational biology, and can be defined as, "conceptualizing biology in terms of molecules and then applying informatics techniques to understand and organize the information associated with these molecules, on a large scale.
An example would be the selection and domestication of plants via micropropagation. Another example is the designing of transgenic plants to grow under specific environments in the presence or absence of chemicals.
One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture.
An example of this is the engineering of a plant to express a pesticidethereby ending the need of external application of pesticides.Oct 01, · But don’t tell that to this year’s TR honorees in biotechnology and medicine, a group intent on turning recent biomedical advances into practical technologies with an immediate schwenkreis.com: Erika Jonietz.
