Practical Applications of Biotechnology

Bioprocessing technology

Uses whole living cells or components of them to manufacture desired products.

Most common whole cells used are yeast and bacteria (one-celled organisms).

Most common components are enzymes (proteins that catalyze chemical reactions).

Cells isolated from animals and plants also are used to produce desired products.

2. Genetic engineering

  • The technique of removing, modifying or adding genes to a DNA molecule to change the information it contains.
  • More specifically is known as recombinant DNA (rDNA) technology.
  • The product of rDNA technology is known as a genetically modified organism, or GMO.
  • Example: Gene for human insulin inserted into E.coli → bacteria that make human insulin (a biopharmaceutical).

Practical Applications of Biotechnology

1. Agricultural applications — better crops, improved animal health

2. Medical and health care applications — new tests, vaccines, medicines

3. Chemical and environmental applications — better manufacturing processes and consumer products

Practical Applications of Biotechnology

1. Agricultural applications — crops and forest

  • Improve crop yields by introducing genes that

confer resistance to insects, tolerance

to herbicides and resistance to environmental

stresses (drought, heat, cold).

  • Create disease- and insect-resistant trees to help meet

demand for wood products.

Practical Applications of Biotechnology

1. Agricultural applications — improve animal health

  • Better detection of disease
  • More nutritious feed
  • New and more effective vaccines
  • Improved treatments for diseases

2. Medical and Health Care

Applications

  • New diagnostic tests

Example: quick test for strep throat

  • MANY new treatments for diseases and conditions

Examples: diabetes, stroke, anemia, cystic fibrosis,

hemophilia, leukemia and other cancers; hepatitis;

rheumatoid arthritis; growth deficiencies; transplant rejection

3. Chemical and Environmental

Applications (Industrial Biotechnology)

  • Produce enzymes used in laundry detergents.
  • Use genetically modified microorganisms that

break down industrial waste.

  • Develop bio-based, biodegradable plastics.
  • Improve manufacturing that reduces the amount of waste products.
