The Advances in Biotechnology
What exactly is biotechnology? There are plenty of definitions being floated around by different organizations. Using biology in order to develop technology, with regard to product development and research, is what biotechnology entails. The fields biotechnology can feasibly be used in include agriculture, medicine, food science, environment and robotics.
The human involvement in manipulating their environment is now at remarkable levels. From the most basic direct organism manipulations such as fermenting beer and culturing bacteria to advanced nucleotide-based organ regeneration and animal cloning, our knowledge and technology has advanced far beyond what anyone would've expected just a decade ago.
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.
The biotechnology we know today started gaining attention only about twenty years ago, when genetics were discovered to be the primary element for synthesizing essential proteins in an organism. The discovery of DNA and the related development of molecular biology was the true beginning of biotechnology as we know it now.
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.
Modern biotechnology is practiced in three different categories - red, white and green. Red Biotechnology is when the genetically altered microorganisms are used to produce medical and pharmaceutical substances, such as proteins, vitamins, antibiotics and vaccines etc. It's also used in 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.
