Study Notes
The Science of Microbiology
- Microbiology revolves around two interconnected themes: understanding microscopic organisms and applying knowledge for human and planetary benefits.
Importance of Microorganisms
- First living organisms on Earth
- Found everywhere life is possible
- Most numerous organisms on the planet
- Global ecosystem depends on their activities
- Influence human society in many ways
Basic and Applied Microbiology
- Basic Microbiology: studies the fundamental nature and properties of microorganisms
- Applied Microbiology: employs knowledge to control and use microorganisms beneficially
The Future of Microbiology
- Keeps us healthy
- Keeps the environment clean
- Makes air breathable
- Supports and protects crops
- Provides new sources of medicine
- Helps with food digestion
A Brief History of Microbiology
- Historical roots date back to A. Hooke, van Leeuwenhoek, and Cohn (discovery linked to the microscope invention)
Louis Pasteur
- French chemist
- Disproved spontaneous generation theory using the swan-neck flask
- Developed the Germ Theory of Fermentation (wine making)
- Developed the Germ Theory of Disease
- Introduced sterilization and pasteurization
Robert Koch
- German physician
- Developed methods for studying bacteria in pure culture
- Established Koch postulates (criteria to prove a microbe causes a disease)
Joseph Lister
- English surgeon
- Introduced the concept of aseptic technique
- Developed antiseptic surgery
- Known as the "father of antiseptic surgery"
Developments in Nonmedical Microbiology
