Study Notes
Definition and Types
- Microorganisms: living organisms that are too small to be seen with the naked eye, typically measuring between 0.1-5.0 μm in diameter.
- Types:
- Bacteria: single-celled prokaryotes, e.g. E. coli, Staphylococcus aureus
- Viruses: tiny particles made up of genetic material and protein, e.g. influenza, HIV
- Fungi: eukaryotes, e.g. yeast, mold
- Protozoa: single-celled eukaryotes, e.g. amoeba, paramecium
- Algae: simple aquatic plants, e.g. green algae, diatoms
Characteristics
- Microorganisms are incredibly diverse, with different species adapted to various environments
- Most microorganisms are harmless to humans, and many are beneficial
- Microorganisms can be found almost everywhere, from extreme environments to the human body
- They play a crucial role in many ecosystem processes, such as decomposition, nutrient cycling, and carbon sequestration
Microbial Growth and Metabolism
- Microorganisms can grow rapidly, with some species doubling in number every 20-30 minutes
- They can utilize a wide range of energy sources, including light, organic compounds, and inorganic compounds
- Microorganisms have diverse metabolic processes, including fermentation, respiration, and photosynthesis
Importance of Microorganisms
- Microorganisms are essential for human health, participating in digestion, immune system function, and production of vitamins
- They are used in various industrial applications, such as food production, bioremediation, and biotechnology
- Microorganisms play a key role in environmental processes, such as decomposition, nitrogen cycling, and climate regulation
Microbial Interactions
- Microorganisms can interact with each other and their environment through various mechanisms, including:
- Symbiosis: mutually beneficial relationships, e.g. coral-algae symbiosis
- Competition: competition for resources, e.g. nutrient competition between microorganisms
- Predation: predator-prey relationships, e.g. protozoa predating on bacteria
- Cooperation: working together to achieve a common goal, e.g. biofilm formation
