Study Notes
Microbiology
- Microbiology is the study of microbes, which are microscopic organisms.
Types of Microbes
- Cellular microbes are living organisms, such as bacteria, archaea, some algae, protozoa, and fungi.
- Acellular microbes are nonliving entities, like viroids, prions, and viruses.
Microbes in Our World
- Microbes are ubiquitous; they exist almost everywhere.
- Photosynthetic microbes, like algae and cyanobacteria, produce a significant portion of the oxygen in our atmosphere.
- Microbes are crucial for the decomposition of dead organisms and waste products.
- Saprophytes are organisms that live on dead or decaying organic matter.
- Bioremediation uses microbes to clean up toxic wastes and industrial byproducts.
Microbes and Disease
- Microbes that cause disease are sometimes called pathogens.
