Takeaways

• 😀 Biotech is a branch of biology focused on utilizing living organisms to produce goods and services that benefit humans.
• 😀 Biotechnology agents can be used in whole (e.g., bacteria) or in part (e.g., DNA or enzymes) for various processes.
• 😀 Louis Pasteur's discovery of microorganisms in food and Edward Wilson's fermentation of alcohol marked significant steps in biotechnology.
• 😀 Conventional biotechnology involves simple tools and fermentation processes using microorganisms like yeast, bacteria, or fungi.
• 😀 Modern biotechnology utilizes advanced tools and techniques such as DNA engineering, sterilization, and large-scale production.
• 😀 Examples of conventional biotechnology include processes like making tape, cheese, oncom, yogurt, and tempeh through fermentation.
• 😀 Modern biotechnology has applications in agriculture, such as tissue culture to propagate superior plants, and genetic modification to create transgenic crops.
• 😀 In medicine, modern biotechnology is used for antibiotic production, cloning, monoclonal antibody production, and the creation of vaccines.
• 😀 Biotechnology also plays a role in animal husbandry through techniques like artificial insemination to produce superior livestock.
• 😀 Environmental biotechnology helps break down waste, such as plastic degradation by Ideonella sakaiensis, and oil spill cleanup by Pseudomonas aeruginosa.

Q & A

What is biotechnology?

Biotechnology is a branch of biology that studies the use of living organisms to produce goods and services for human benefit, aiming to maximize human profits.

What is the difference between conventional and modern biotechnology?

Conventional biotechnology uses simple tools and methods, often involving fermentation, and is typically done on a small scale. Modern biotechnology, on the other hand, uses advanced tools, sterilization processes, and includes techniques like genetic engineering and enzymatic processes, usually performed on a large scale.

What are some examples of conventional biotechnology products?

Examples of conventional biotechnology products include tape (fermented from cassava or glutinous rice), cheese, yoghurt, tempeh, and bread, all of which are produced using microorganisms like yeast, fungi, or bacteria.

What is the historical significance of Louis Pasteur in biotechnology?

Louis Pasteur, a French scientist, was one of the pioneers of biotechnology. He discovered microorganisms in food in 1870, laying the groundwork for future developments in fermentation and microbial science.

How does the process of making tape relate to biotechnology?

The process of making tape involves fermenting cassava or glutinous rice using the yeast Saccharomyces cerevisiae, which breaks down sugars into alcohol and carbon dioxide, a key example of biotechnology in action.

What is plant tissue culture and how is it used in biotechnology?

Plant tissue culture is a modern biotechnology technique used to multiply plants, particularly superior plant varieties, by exploiting the totipotency of plant cells. It is commonly used for cloning crops like orchids or oil palm.

What are transgenic plants and how are they created?

Transgenic plants are genetically modified plants created by altering their DNA to give them advantageous traits, such as resistance to pests. This process involves inserting foreign genes into plant DNA.

How is biotechnology applied in the field of health?

Biotechnology in health includes the production of antibiotics using microorganisms, cloning organisms like Dolly the sheep, the creation of monoclonal antibodies, genetic engineering for vaccines, and in vitro fertilization for reproductive assistance.

What is genetic engineering and how does it relate to insulin production?

Genetic engineering is the process of modifying the DNA of organisms. In the case of insulin production, the gene for human insulin is inserted into bacteria (such as E. coli), which then produces insulin for medical use.

What are some environmental applications of biotechnology?

Biotechnology can be used for environmental protection, such as using bacteria to break down plastic waste (e.g., Ideonella sakaiensis) or to clean up oil spills (e.g., Pseudomonas aeruginosa).
