Study Notes
Classification Systems
- Five kingdoms in the Whittaker system: fungi, protista, Monera, Animalia, plantae.
- Bacteria are classified into the same kingdom within this system.
- The protozoan Entamoeba histolytica is classified under the kingdom Protista.
- In the traditional Whittaker system, algae belong to the kingdom Protista.
Eukaryotic and Prokaryotic Organisms
- Eukaryotic organisms can be unicellular or multicellular.
- Yeasts belong to the Kingdom Fungi and Domain Eukarya.
- Streptococcus bacterium is classified in the Kingdom Monera.
- Bacteria like Staphylococcus are in the Domain Bacteria.
- Archaea are prokaryotic organisms often found in extreme environments.
Taxonomy and Nomenclature
- Taxonomy involves naming and classifying living organisms.
- Hierarchy of classification mnemonic: "Dear King Phillip Came Over For Good Spaghetti," representing domain, kingdom, phylum, class, order, family, genus, species.
- In both classification systems, species is the most specific level just below genus.
- Classification arranges organisms based on relationships and history.
- Nomenclature is a systematic approach for naming organisms and biological structures.
Microbiology Fundamentals
- Branches of microbiology include: bacteriology, mycology, protozoology, virology, parasitology, phycology, morphology, physiology, taxonomy, microbial genetics, molecular biology, microbial ecology.
- Identification in taxonomy means determining an organism's exact identity based on its characteristics.
Genetics and Evolution
- Recombinant DNA technology involves transferring genetic material between organisms for producing desired proteins.
- Infectious diseases, caused by microorganisms, are significant contributors to global mortality rates.
- Antonie van Leeuwenhoek is credited with developing the first single-lens microscope.
- The principle of evolution suggests living organisms change gradually through natural selection.
Environmental and Health Impact
- Algae are photosynthetic microorganisms often found in aquatic systems, both unicellular and multicellular.
- Bioremediation is the process by which microorganisms decompose harmful chemicals.
- Semmelweis established a link between unwashed hands of physicians and infections in maternity wards.
Genetic Engineering
- Genetic engineering, or recombinant DNA technology, modifies an organism's genetic structure for new product creation.
