Study Notes
Branches of Microbiology
- Bacteriology: study of bacteria
- Virology: study of viruses
- Mycology: study of fungi
- Parasitology: study of parasites
- Immunology: study of immune system and its interactions with microorganisms
- Microbial Ecology: study of microorganisms in their natural environments
Types of Microorganisms
-
Bacteria: prokaryotic cells, typically 0.5-5.0 μm in size
- Examples: E. coli, Staphylococcus aureus
-
Viruses: infectious particles, typically 20-400 nm in size
- Examples: Influenza, HIV
-
Fungi: eukaryotic cells, typically 2-10 μm in size
- Examples: Yeast, Mold
-
Protozoa: eukaryotic cells, typically 10-50 μm in size
- Examples: Amoeba, Giardia
-
Algae: eukaryotic cells, typically 1-10 μm in size
- Examples: Green algae, Diatoms
Microbial Growth and Nutrition
- Nutrient sources: carbon, nitrogen, phosphorus, oxygen, and other essential elements
- Metabolic processes: photosynthesis, respiration, fermentation
- Growth factors: temperature, pH, moisture, oxygen availability
- Microbial growth curves: lag phase, log phase, stationary phase, death phase
Microbial Interactions and Relationships
- Symbiosis: mutualism, commensalism, parasitism
- Antagonism: competition, amensalism, predation
- Microbial communities: biofilms, consortia, soil microbiome
Microbiology Applications
- Medicine: diagnosis, treatment, and prevention of infectious diseases
- Food and Beverage: fermentation, spoilage, and preservation
- Environmental Science: bioremediation, biodegradation, and pollution control
- Agriculture: plant pathology, soil fertility, and pest control

- Algae are eukaryotic cells, typically 1-10 μm in size, with examples including Green algae and Diatoms
Microbial Growth and Nutrition
- Microorganisms require carbon, nitrogen, phosphorus, oxygen, and other essential elements as nutrient sources
- Metabolic processes include photosynthesis, respiration, and fermentation
- Temperature, pH, moisture, and oxygen availability are growth factors that impact microbial growth
- Microbial growth curves consist of the lag phase, log phase, stationary phase, and death phase
Microbial Interactions and Relationships
- Symbiosis can take the form of mutualism, commensalism, or parasitism
- Antagonism can manifest as competition, amensalism, or predation
- Microbial communities can form biofilms, consortia, and soil microbiomes
Microbiology Applications
- Microbiology is crucial in medicine for diagnosis, treatment, and prevention of infectious diseases
- In the food and beverage industry, microbiology plays a role in fermentation, spoilage, and preservation
- Microbiology is essential in environmental science for bioremediation, biodegradation, and pollution control
- In agriculture, microbiology is important for plant pathology, soil fertility, and pest control
