Study Notes
Safety, Ethics, and Welfare in Biotechnology
- Public debate is essential for the growth of biotechnology and its scrutiny in the foreseeable future.
- Public understanding of biotechnology could hasten public acceptance.
White Biotechnology
- A branch of industrial biotechnology that uses living cells (bacteria, fungi) and enzymes to synthesize easily degradable products.
- Examples: production of bioplastics from microbial polymers, and biofuel production from starch and lignocelluloses.
Biodegradable Materials and Bioremediation
- Biodegradable materials can be broken down by biological action, e.g., by microorganisms (bacteria, fungus, etc.).
- Bioremediation: use of organisms to remove materials from contaminated sites.
Key Stages in Industrial Biotechnology
- Upstream processing: preparation of raw materials for use as a food source for microorganisms.
Traditional and Modern Biotechnology
- Traditional biotechnology encompasses processes such as brewing, baking, winemaking, and sewage treatment.
- Modern biotechnology began in the 1970s with genetic engineering, leading to breakthroughs in medicine and agriculture.
Genetic Engineering and Its Impact
- Genetic engineering allows for precise alteration of genetic constitution of living organisms.
- Impact: breakthroughs in medicine, agriculture, pharmaceutical drugs, healthier foods, selective pesticides, and innovative environmental technologies.
Introduction to Biotechnology
- Biotechnology refers to the use of microbial, animal, or plant cells or enzymes to synthesize, break down, or transform materials.
Historical Development of Biotechnology
- 1917: Karl Ereky used the term to refer to industrial fermentation processes and integrated processes for large-scale production.
- 1941: A Danish microbiologist used the term to refer to precise selection of yeast strains.
- 1960s: Biotechnology was used to describe industrial production of goods and services using biological processes.
- Modern definition: manipulation of living organisms or their components to produce commercial products.
