Developments in Biotechnology
Biotechnology can be defined in many ways and although different involved organizations do explain it in their own terms, ultimately, biotechnology is the use of biology as the foundation for developing various technologies as applied to research and product development. So, biotechnology can be used in food science, agriculture, environment, medicine and even robotics fields.
We have always tried to manipulate and control the world, change it to suit our needs. We do that when we ferment beer, we do it when we culture bacteria, and now we have moved to new levels that would have been considered impossible a few decades back - we have cloned animals and research has turned to concepts like nucleotide-based organ regeneration.
Biotechnology was in practice much before the actual term was used to describe it. The basics began with very simple scientific methods such as preserving foods for winter. The first fruit juice fermentation to produce alcohol is believed to have been done in 6000 BC. Back then, it was more of an art than an actual science.
DNA and genetics played a big part in bringing biotechnology as a science to the forefront. It was recognized as a science when it was discovered that genetics were what played the major part in the synthesizing of essential proteins in any organism.
The eighties saw technological advances being made in leaps and bounds. The same was true in the case of biotechnology. Use of biotechnology in the fields of medicine and biological research became very important and more common. The concept of transgenic organisms was discovered, which led to vast advancement in the fields of disease resistance and productivity rates. Now we have plant-generated pharmaceuticals and production of antibiotics and insulin, as a direct result of this research.
There are three different kinds of biotechnology that are practiced - red biotechnology, white biotechnology and green biotechnology. Red biotechnology deals with the genetic alteration of microorganisms for use in the production of pharmaceutical and medical substances like vitamins, vaccines, antibiotics and proteins, as well as in the field of genome manipulation.
White Biotechnology is also known as bio-manufacturing and Grey Biotechnology. This is not yet a completely established field and involves manipulating live organisms to create important industrial chemicals. Some of the organisms used in these techniques include bacteria, enzymes, moulds and yeast.
Green Biotechnology is important in agriculture - making better produce that stays fresh and lasts longer, and is more nutritious. This is something people have been doing for a long time - making sturdier crops, like cross-bred wheat for example.
