Study Notes
Antibiotics and Microorganisms
- Antibiotics specifically target prokaryotic organisms because they inhibit cell wall formation, which is unique to prokaryotes.
- Only prokaryotic organisms (bacteria) are affected by antibiotics, as eukaryotic cells (like human cells) do not have a cell wall.
Bioremediation
- The primary factor required for successful bioremediation is microorganisms that can degrade pollutants.
Microorganisms and Disease
- Giardia lamblia causes backpackers' diarrhea.
- The bubonic plague was typically fatal within 4-7 days if left untreated.
Scientists and Discoveries
- Joseph Priestley is credited with the discovery of oxygen.
- Louis Pasteur used swan-necked flasks to prove biogenesis, demonstrating that microorganisms cannot spontaneously generate.
- Dr. Ignaz Semmelweis used handwashing with soap and water to reduce mortality rates in his ward.
- Louis Pasteur discovered the process of fermentation, which saved the French wine industry.
- Viruses are a type of microorganism that must infect a host cell to replicate.
Viruses
- Viruses can be considered parasites because they require a host cell to replicate.
- The primary feature of endospores that allows them to resist heat and drying out is their low water content and thick, protective coatings.
- To visualize a virus, an electron microscope is required.
- The core of a virus is surrounded by a protein coat called a capsid.
Historical Experiments
- Louis Jablot's experiment covering a bowl and leaving one uncovered demonstrated that microorganisms are present in the air and can contaminate food.
- Schroder and Van Dusch passed air through a red-hot tube before putting it in a flask, killing any microorganisms present, to demonstrate the role of microorganisms in fermentation.
