Study Notes
Introduction to Microbiology
- Microbiology is the study of microbes (small living organisms)
- Microbes include bacteria, archaea, fungi, algae, viruses, and protozoa
- Microbiology encompasses applied (practical uses) and pure (basic research) microbiology
Branches of Applied Microbiology
- Medical Microbiology
- Veterinary Microbiology
- Food Microbiology
- Water (or Aquatic) Microbiology
Branches of Pure Microbiology
- Bacteriology: The study of bacteria
- General Bacteriology: Examines the biology of bacteria
- Systematic Bacteriology: Classifies bacteria, studies their properties, and the relationships between different types (diversity and genetic relationships)
- Mycology: The study of fungi
- Phycology: The study of algae
- Virology: The study of viruses
- Immunology: Focuses on the body's immune response to microbes
- Microbial Physiology: Examines the structure, metabolism, and growth of microbes
- Microbial Ecology: Studies the interactions between microbes and their environment
- Microbial Genetics: Focus on the genetics of microbes (genes and their functions)
Importance of Microbiology
- Maintaining human health
- Industrial applications (e.g., food production, biotechnology)
- Nature balance (decomposition of dead matter)
- Environmental roles (e.g., bioremediation)
- Improving animal (especially fish) production
Taxonomy of Microbes
- Living organisms are categorized into kingdoms based on cell structure and energy systems
- Five kingdoms include: Animals, Plants, Fungi, Protista, and Monera (Bacteria)
- Two main classifications (based on cell structure): Prokaryotes and Eukaryotes
Prokaryotes
- Small, simple cells without a nucleus or membrane-bound organelles
- Have a single circular chromosome of DNA
- DNA is located in the cytoplasm in a region called the nucleoid
- Genetic material can also include plasmids (small circular DNA molecules)
- Lack histones
- Cell division = binary fission
- Ribosomes are 70S
- Respiration = plasma membrane
- Cell wall present
- Some have capsules, flagella, pili etc.
Eukaryotes
- Larger, complex cells with a nucleus and membrane-bound organelles
- Multiple linear chromosomes
- DNA is contained within the nucleus
- Cell division through mitosis and meiosis
- Ribosomes are 80S
- Cell wall is present in some eukaryotes
- Respiration in mitochondria
- Includes fungi, algae, protozoa, animals, and plants
Prokaryotic and Eukaryotic Cell Comparison (Diagram)
- Clear visual comparison of the structures of prokaryotic and eukaryotic cells is available. Showing the differences in their organelles and structures.
