WHAT IS BIOTECHNOLOGY?

Written by T. Divya

Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences to achieve the application of organisms and parts thereof for products and services. The term biotechnology was first used by Károly Ereky in 1919 to refer to the production of products from raw materials with the aid of living organisms. The core principle of biotechnology involves harnessing biological systems and organisms, such as bacteria, yeast, and plants, to perform specific tasks or produce valuable substances.

What is Biotechnology?

Biotechnology involves the use of living systems and organisms to develop or make products, often through manipulating cellular and biomolecular processes. The field combines principles from biology and technology to create innovations in areas such as medicine, agriculture, industrial processes, and environmental management.

Types of Biotechnology

1. Medical Biotechnology (Red Biotechnology)

   - Applications: Development of drugs, gene therapy, regenerative medicine, vaccines, and diagnostics.

   - Examples: Monoclonal antibodies for cancer treatment, CRISPR gene editing for genetic disorders, mRNA vaccines for COVID-19, and PCR tests for disease detection.

2. Agricultural Biotechnology (Green Biotechnology) 

   - Applications: Enhancing crop yields, developing pest-resistant and disease-resistant crops, improving nutritional content, and creating biofertilizers and biopesticides.

   - Examples: Genetically modified organisms (GMOs) like Bt corn and herbicide-resistant soybeans, CRISPR-edited crops for drought resistance, and biofertilizers that promote soil health.

3. Industrial Biotechnology (White Biotechnology)

   - Applications: Production of biofuels, bioplastics, and industrial enzymes, and the use of microbial fermentation processes.

   - Examples: Ethanol production from biomass, biodegradable plastics, enzymes in detergents and food processing, and microbial synthesis of chemicals.

4. Environmental Biotechnology (Gray Biotechnology)

   - Applications: Pollution control, waste management, bioremediation, and environmental monitoring.

   - Examples: Microbes that degrade oil spills, bacteria that break down toxic chemicals in soil and water, and biosensors that detect environmental pollutants.

5. Bioinformatics (Blue Biotechnology)

   - Applications: Managing and analyzing biological data, genomics, proteomics, and personalized medicine.

   -Examples: Genome sequencing, bioinformatics software for genetic research, and databases that store and analyze biological information.

6. Marine Biotechnology (Blue Biotechnology)

   - Applications: Exploration and utilization of marine organisms for pharmaceuticals, enzymes, and other bioactive compounds.

   - Examples: Extraction of anticancer compounds from marine algae, development of enzymes from marine bacteria for industrial applications, and sustainable aquaculture practices.

 Applications of Biotechnology
