Biotechnology: definition, history, types and application
Did you know that biotechnology plays an important role in many aspects of life, from agriculture to the marine sector?
In addition to contributing to improving the quality of life, this technology also supports environmental conservation efforts in a sustainable manner.
So, what is Biotechnology? In this article, we will discuss in depth the meaning of Biotechnology, its basic concepts, as well as various examples of its application in everyday life. Come on, listen!
Understanding and basic concepts of Biotechnology
Biotechnology is a branch of science that combines the principles of biology and technology to create or modify products and processes that are useful to humans and the environment.
Etymologically, the term bio refers to living organisms, while technology refers to the application of Science in designing certain tools, methods or systems.
Thus, Biotechnology can be defined as the utilization of biological systems to produce innovative products and technologies.
According to the Encyclopedia of Agriculture and Food Systems (2014), biotechnology is defined more specifically as the use of living organisms or biological systems in industrial activities, including the treatment of waste and the production of various essential materials.
Along with the development of Science and technology, the application of Biotechnology now covers various sectors, ranging from food, health, energy, to the environment.
One of the main concepts in biotechnology is the use of microorganisms in the production process. For example, the bacterium Acetobacter xylinum is used in the preparation of nata de coco, while the fungus Rhizopus oryzae is used in the fermentation of tempeh.
Genetic engineering is also becoming an important part of Biotechnology, where DNA manipulation is used to improve the quality of organisms. Examples include the development of pest-resistant transgenic plants or the production of insulin using Escherichia coli bacteria.
Fermentation is another biotechnological process that plays a major role in the food and energy industries. This process is used in the manufacture of products such as yogurt, cheese, to bioethanol—a renewable energy source that is environmentally friendly.
In the environmental sector, biotechnology contributes through bioremediation techniques to decompose hazardous waste and reduce pollution. In addition, innovations such as bioplastics from biological materials offer a more environmentally friendly alternative to conventional plastics.
History Of Biotechnology
Biotechnology is actually nothing new in human life. Since thousands of years ago, various ancient civilizations have implemented early forms of Biotechnology, albeit without the scientific understanding we have today.
Historical records show that the Babylonians, Egyptians, and Romans had been breeding livestock through the process of artificial selection since about 8000 BC. The goal is to obtain offspring with superior traits, such as high productivity or resistance to disease.
Meanwhile, in other parts of the world, the Chinese have used the fermentation process of milk since about 4000 BC to produce processed foods such as yogurt and cheese. These practices became early examples of conventional Biotechnology, the use of microorganisms and natural processes to produce more durable and nutritious foods.
Significant developments in biotechnology began to be seen in the 19th century. One of the important figures in this history is Gregor Mendel, an Austrian Monk and scientist who has been dubbed “the father of genetics.’Through experiments crossing pea plants, Mendel formulated the laws of inheritance of traits that became the basis for modern genetic science—an important foundation in the development of today’s biotechnology.
Entering the era of modern biotechnology in the 1960s, two scientists named Stewart Linn and Werner Arber succeeded in isolating an enzyme that can inhibit the growth of bacteriophages, viruses that attack Escherichia coli bacteria. This discovery became the starting point of more precise genetic manipulation techniques.
In 1968, three researchers from Johns Hopkins University—H.O. Smith, K.W. Wilcox, dan T.J. Kelley-discovered and characterized the first restriction nuclease enzyme. These enzymes are capable of cutting DNA at specific locations, paving the way for genetic engineering that allows the insertion, cutting, or replacement of genes in an organism’S DNA.
From here, various applications of modern biotechnology that you know today have developed, such as the production of synthetic insulin using bacteria, the development of monoclonal antibodies for disease therapy, and the engineering of transgenic plants that are resistant to pests and extreme climatic conditions.
Types Of Biotechnology
Biotechnology is generally divided into two main categories, namely conventional biotechnology and modern biotechnology.
Both have different approaches, both in terms of methods, technologies used, to scale and production results.
1. Conventional Biotechnology
Conventional biotechnology is an early form of biotechnology that has been used since ancient times. This type uses simple methods without the aid of sophisticated technology, and is often done traditionally on a small scale.
The advantage of conventional biotechnology lies in its simplicity as well as the utilization of natural microorganisms, such as bacteria and fungi, in the production process. One of the most common processes in this type is fermentation, that is, the decomposition of substances by microorganisms to produce new useful products.
Some examples of conventional biotechnology products that you may often encounter in everyday life include tempeh, oncom, tape, tuak, and soy sauce.
Although it has been proven safe and useful for centuries, conventional Biotechnology has its limitations. This technology is less able to cope with modern challenges such as specific pest attacks, complex plant diseases, or the need for mass production in a short time.
2. Bioteknologi Modern
In contrast, modern biotechnology uses advanced scientific and technological principles in its processes.
This type allows directional genetic manipulation to create new organisms or improve certain traits that are not naturally available.
Modern biotechnology is generally applied on an industrial scale, focusing on production efficiency, quality improvement, and solving specific biological problems. Not only microorganisms, this biotechnology also utilizes small components such as cells, tissues, and DNA molecules in the engineering process.
Examples of modern applications of Biotechnology include:
- Production of biologics-based vaccines and drugs
- Manufacture of synthetic insulin using e bacteria. bra
- Development of amino acids for the supplement or food industry
- Industrial waste treatment using microbes
- Bioleaching, which is a technique for separating metals from mine waste using microorganisms
- Making biological pesticides more environmentally friendly
The main advantage of modern biotechnology is its ability to provide quick and efficient solutions to a wide range of global problems, from food crises to environmental pollution.
Examples Of Application Of Biotechnology
Biotechnology has developed rapidly and is widely utilized in various important sectors, from food to marine. Here are some examples of its application:
1. Food Field
In the food sector, biotechnology is used to improve the quality, taste, nutritional content, and durability of food products. One of the most common methods is fermentation, which utilizes microorganisms such as bacteria and fungi.
Examples of its application include:
