10.1 Introduction To Biotechnology

Introduction

Biotechnology is the use of living organisms or their processes and products for the welfare of mankind. It is one of the oldest and most rapidly growing areas of science. From making yogurt and cheese to developing genetically modified crops and life-saving medicines, biotechnology has profoundly impacted human life. This topic introduces biotechnology, its history, and its modern applications.

Definition

Biotechnology can be defined as the "use of living organisms or their processes and products for the welfare of mankind."

Main Idea

• The history of biotechnology is found parallel to the civilization history of man.
• Use of biotechnology can be traced back to the earliest human society.
• Human realized that, to get good and continuous food they should plant their own crops, breed and domesticate their own animals.
• Study of biotechnology began when human discovered to produce yogurt and cheese from fermented milk.
• Early human made wine or beer from fermented juices of fruit, sugarcane and malted barley.
• Since early times of civilization, human are naturally acting as unqualified biotechnologists by baking soft, spongy and tasty bread and bakery items.
• The first farmer who grafted a more beneficial plant over the other less beneficial plants to increase his yield and quality was a performing biotechnologist.
• Rapidly growing human population, led the human to develop new animals with dream characteristics.
• Scientists planned to grow more nutritive and naturally pest-resistant crops.
• Researchers hoped to develop unlimited and purest sources of human medicines.
• Human found the natural ways to remove pollutants from environment and to increase the fertility of the soil and kill insect pest.
• Biotechnology can be defined as the "use of living organisms or their processes and products for the welfare of mankind".
• Early biotechnologists have been using Yeast, to raise bread dough and to prepare alcoholic drinks by alcoholic fermentation and using specific bacteria to make yogurt, butter and cheese by lactic acid fermentation.
• Leather tanning is a prehistoric biotechnological industry which also involve the use of multiple bacteria and other pathogens where people have been preparing the leather even without knowing the underlying mechanism.
• Over the last few decades, advancement in microscopy and fundamental discoveries of biochemical processes in the cells have given rise to modern biotechnology.
• Now biotechnologists have much better understanding to select and use so many new microorganisms and their cell products for human welfare.
• Applications and outcome of modern biotechnology are far advanced than traditional methods like fermentation and selective breeding.
• Modern biotechnology techniques involve genetic engineering, cell fusion, genetically modified organisms, single cell proteins, cell therapies, gene therapies and Nano-biotechnology.
• Modern Biotechnology is now one of the fastest growing areas of science, hence this century has rightly been termed as Century of Biology.
• In view of these developments, Biotechnology has been included among the six priority areas of Science and Technology by the National Commission of Science & Technology of Pakistan.

Detailed Explanation

1. What is Biotechnology?

Biotechnology can be defined as the "use of living organisms or their processes and products for the welfare of mankind".

Simple explanation: Biotechnology is using living things or their products to make useful things for humans.

Why this is important:

• Biotechnology has applications in medicine, agriculture, environment, and industry.
• It has the potential to solve major global challenges.
• It is one of the fastest growing areas of science.

2. History of Biotechnology

The history of biotechnology is found parallel to the civilization history of man. Use of biotechnology can be traced back to the earliest human society.

Early uses:

• Agriculture: Human realized that, to get good and continuous food they should plant their own crops, breed and domesticate their own animals.
• Fermented milk: Study of biotechnology began when human discovered to produce yogurt and cheese from fermented milk.
• Alcoholic drinks: Early human made wine or beer from fermented juices of fruit, sugarcane and malted barley.
• Baking: Since early times of civilization, human are naturally acting as unqualified biotechnologists by baking soft, spongy and tasty bread and bakery items.
• Plant grafting: The first farmer who grafted a more beneficial plant over the other less beneficial plants to increase his yield and quality was a performing biotechnologist.

Simple explanation: Biotechnology is not new. Humans have been using it for thousands of years to make food and drinks.

3. Early Biotechnologists

Early biotechnologists have been using:

• Yeast: To raise bread dough and to prepare alcoholic drinks by alcoholic fermentation.
• Specific bacteria: To make yogurt, butter, and cheese by lactic acid fermentation.
• Leather tanning: A prehistoric biotechnological industry which also involves the use of multiple bacteria and other pathogens where people have been preparing the leather even without knowing the underlying mechanism.

Simple explanation: Early biotechnologists used yeast and bacteria to make bread, beer, yogurt, and cheese, even without knowing how it worked.

4. Modern Biotechnology

Over the last few decades, advancement in microscopy and fundamental discoveries of biochemical processes in the cells have given rise to modern biotechnology.

What changed:

• Biotechnologists now have much better understanding to select and use so many new microorganisms and their cell products for human welfare.
• Applications and outcome of modern biotechnology are far advanced than traditional methods like fermentation and selective breeding.
• Modern biotechnology techniques involve genetic engineering, cell fusion, genetically modified organisms, single cell proteins, cell therapies, gene therapies and Nano-biotechnology.

Simple explanation: Modern biotechnology uses advanced techniques like genetic engineering to modify organisms for human benefit.

5. Importance of Modern Biotechnology

Modern Biotechnology is now one of the fastest growing areas of science, hence this century has rightly been termed as Century of Biology.

In view of these developments, Biotechnology has been included among the six priority areas of Science and Technology by the National Commission of Science & Technology of Pakistan.

Simple explanation: Biotechnology is a rapidly growing field. Pakistan has recognized it as a priority area for science and technology.
