History of biotechnology

© Wikipedia Brewing was an early example of biotechnology

The history of biotechnology can be traced back to the early 19th century when Louis Pasteur discovered that microorganisms could cause disease. The first major breakthrough in the field was the discovery of DNA by James Watson and Francis Crick in 1953. This discovery led to a revolution in biology, which resulted in the development of recombinant DNA technology (RDT). In 1974, Paul Berg published his book “Molecular Biology of the Gene”, which became one of the most influential books in the field of molecular biology. Since then, Recombinant DNA Technology has become an integral part of biological sciences.

The first commercial application of biotechnology was the production of insulin for diabetes treatment. It was developed by Dr. Frederick Banting and Charles Best at the University of Toronto in 1921. However, it took almost 50 years before this product reached the market. In 1981, Genentech Inc. was established to develop humanized antibodies. In 1982, Genentech produced the first monoclonal antibody against cancer. In 1986, Genentech introduced Humulin, the world’s first commercially available recombinant human insulin. 

Modern Biotechnology

The modern biotechnology sector is growing at a rapid pace. It is estimated that the global biotechnology market size was $200 billion in 2010. According to the World Health Organization (WHO), it is expected to reach $300 billion by 2020. The United States leads the world in terms of biotechnology investment. The U.S. government spends over $41.7 billion every year on biomedical research. As per the National Institutes of Health (NIH), the U.S. invests nearly 20% of its total budget in biomedical research.

The biotechnology industry employs approximately 1 million people worldwide. A large number of these employees are employed in pharmaceutical companies. However, the demand for skilled workers is increasing day by day. Therefore, the employment rate is expected to increase significantly in the coming years. 

Four main types of Biotechnology:

  • Medical Biotechnology  (Red)
  • Industrial Biotechnology (White)
  • Environmental Biotechnology (Green)
  • Marine Biotechnology (Blue)

Approaches and tools in Biotechnology

There are two approaches in biotechnology:

  1. the classical approach
  2. the systems approach

The classical approach involves the use of traditional laboratory techniques. These include cell culture, genetic transformation, protein purification, etc. The systems approach focuses on the whole organism or ecosystem. It uses mathematical modeling, computer simulation, and computational analysis to understand how the system works and to predict its future behavior.

Applications of Biotechnology

Biotechnology is being used in a variety of industries including food processing, pharmaceuticals, agriculture, energy, environment, and medicine. Some of the applications of biotechnology include:

Biotechnology and Food Science

Food biotechnology refers to the use of biotechnological methods to improve the quality and safety of foods. It includes the use of genetically modified organisms (GMOs), fermentation, and enzyme engineering. Currently, GMOs have been approved for sale in many countries. They are grown in large quantities and sold directly to consumers without passing through any government approval process. Due to their high yield and low cost, they are rapidly replacing conventional crops. For example, corn, soybeans, and cotton are now mostly GMO-based. Fermentation also plays an important role in the food industry. It is used to make cheese, wine, beer, yogurt, and vinegar. Enzymes are another essential part of the food industry. They play a key role in food preparation and preservation. Most enzymes are derived from microorganisms. They are used in the dairy, meat, and vegetable industries.

Pharmaceutical industry

The pharmaceutical industry uses biotechnology extensively. Pharmaceutical companies use recombinant DNA technology to create vaccines against diseases like AIDS, cancer, and malaria. Other biotechnologies include tissue culturing, stem cell research, and bioinformatics. Stem cells are undifferentiated cells that can become any type of cell in the body. They are found in embryos, adult tissues, and umbilical cord blood. They can be harvested from embryos and adult tissues. Stem cells are useful because they can be used to treat patients who suffer from genetic disorders. Bioinformatics is the study of how information is stored and processed by living things. It helps scientists understand how genes work together to form proteins. It also helps scientists identify mutations in genes associated with the disease.


Environmental biotechnology deals with environmental issues such as pollution, waste management, air, and water purification, and climate change. The main goal of environmental biotechnology is to minimize or eliminate harmful effects caused by human activities. In order to achieve this goal, it is necessary to develop new technologies that can clean up polluted areas and remove pollutants from the environment.


Corn generated ethanol biofuel

In recent years, there has been increased interest in using renewable energy sources. Biofuels are fuels produced from biological materials. Examples of biofuels are ethanol and biodiesel. Ethanol is made from sugar cane, corn, wheat, and other plants. Biodiesel is made from oilseeds, animal fats, and recycled cooking oils. Both these types of fuel are more environmentally friendly than fossil fuels. However, they still produce carbon dioxide during combustion. This makes them less desirable than fossil fuels. There is currently no way to completely avoid producing carbon dioxide. Therefore, researchers are looking for ways to reduce the amount of carbon dioxide released into the atmosphere. They are also searching for ways to recycle carbon dioxide back into the environment.

Agricultural Biotechnology

Biotechnology plays a vital role in agriculture and is used in the development of Agricultural products. Plants are genetically modified to make them resistant to pesticides and herbicides. These chemicals have negative side effects on humans and animals. Some crops are engineered to contain higher levels of protein than normal. Soybeans are engineered to contain high amounts of omega-3 fatty acids. Wheat is engineered to contain gluten which is used in bread making. Rice is engineered to contain lower amounts of starch which reduces its weight and increases shelf life. The world’s population continues to grow at an alarming rate. As people live longer, they require more food. Food production must be increased to meet the demand. Biotechnology is being used to improve the efficiency of farming. New varieties of seeds are developed to help increase crop yield. Genetically modified organisms (GMOs) are also being used to create pest-resistant crops.

Human Genome Project

It was a project started in 1990 to map out the entire human genome. This project was completed in 2003. It took about 10 years to do this task. There were 2 phases to this project. Phase I involved mapping out all of the DNA sequences on chromosomes 1-22 and X. Phase II involved mapping out all of the chromosomes 23 and Y. The Human Genome Project cost $2 billion dollars. Scientists hope to use the information found in the human genome to treat diseases like cancer and diabetes.

Industrial Applications of Biotechnology

There are many industrial applications of biotechnology. One example is the production of enzymes. Enzymes are proteins that speed chemical reactions. For instance, one type of enzyme speeds the breakdown of carbohydrates. Another type of enzyme speeds the formation of vitamin C. Many pharmaceutical companies have used genetic engineering to develop new drugs. Pharmaceutical companies can now manipulate genes to change how a drug works. This allows them to make better drugs with fewer side effects. Biotechnology is also used to produce vaccines.

Aspects of Biotechnology

The following aspects of biotechnology have been studied:

  • Molecular Biotechnology

Molecular biology involves the manipulation of nucleic acids, including deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein. Molecular biologists manipulate DNA to make changes in organisms. For example, molecular biologists have used recombinant DNA techniques to make viruses resistant to antibiotics. They have also created transgenic animals that carry a gene for a specific trait. These genetically modified animals are called GMOs. Molecular biologists are studying the structure of RNA and DNA. They are also investigating how genes work.

  • Genetic engineering

Genetic engineering uses genetic technology to modify living things. Genetic engineers use recombinant DNA techniques to create GMOs. Recombinant DNA is DNA that comes from two different species. For example, scientists may take a gene from a bacterium and insert it into another organism’s genome. If the inserted gene codes for the desired characteristic, then the resulting organism will be better able to survive and reproduce. Genetic engineers may also alter the structure of an organism’s chromosomes. Chromosomes contain genes that determine characteristics such as eye color and hair color. By altering the chromosome, scientists can change the traits of an organism.

  • Drug Development

The pharmaceutical industry is one of the most important sectors of the biotech industry. Pharmaceutical companies seek out drugs that treat diseases. Drugs are usually developed through research on laboratory animals. Scientists first test their drug on mice. If the results are promising, they move on to larger mammals like rabbits or dogs. Once they find a drug that works well in animals, they begin human trials. Human clinical trials involve testing the new drug on humans. The FDA requires all drugs to undergo extensive testing before being approved for sale.

  • Bioprocess Engineering

They study the relationship between genetics and behavior. They also study the history of life on Earth over time.

  • Drug Discovery

Drug discovery is the process of developing new drugs to cure diseases. The goal of drug discovery is to find safe and effective medications for the treatment of various diseases. New discoveries are based on finding out what happens when you take chemicals that affect different parts of the human body. Scientists often start with an initial compound and test it against many different targets. Drug development takes a long time because scientists must conduct experiments that prove whether a particular target affects the way the body works. Once they have proven their hypothesis, they may begin testing the drug in humans.

  • Biochemistry

Biochemistry is the branch of chemistry that deals with the chemical processes within living organisms. It studies the structure and function of organic compounds. Biochemists study the biochemical reactions involved in metabolism. They also study the interactions between nutrients and the human body.
