Study Notes

Microorganisms and Environmental Remediation

  • Microorganisms play a crucial role in environmental remediation by degrading pollutants and toxins in soil, water, and air.
  • Bioremediation: the use of microorganisms to clean up pollutants, such as oil spills, heavy metals, and pesticides.
  • Examples of microorganisms used in bioremediation:
    • Bacteria: Pseudomonas, Rhodococcus, and Deinococcus
    • Fungi: White rot fungus (Phanerochaete chrysosporium)
  • Microorganisms can also be used to clean up pollutants in situ, reducing the need for excavation and transportation.

Microorganisms and Food Production

  • Microorganisms are essential in food production, particularly in fermentation processes.
  • Fermentation: a metabolic process in which microorganisms convert organic compounds into energy.
  • Examples of microorganisms used in food production:
    • Yeast (Saccharomyces cerevisiae): bread, beer, and wine
    • Bacteria (Lactobacillus acidophilus): yogurt, cheese, and sauerkraut
    • Molds (Penicillium roqueforti): blue cheese
  • Microorganisms can also be used to improve food safety and quality by:
    • Extending shelf life
    • Enhancing nutritional content
    • Reducing spoilage

Microorganisms and Infectious Disease

  • Microorganisms are the primary cause of infectious diseases, including:
    • Bacterial infections (e.g., tuberculosis, pneumonia)
    • Viral infections (e.g., influenza, HIV)
    • Fungal infections (e.g., candidiasis, aspergillosis)
  • Microorganisms can also be used to prevent and treat infectious diseases:
    • Vaccines: use of weakened or killed microorganisms to stimulate immune response
    • Probiotics: use of beneficial microorganisms to promote gut health and prevent infection
    • Antibiotics: use of microorganisms or their products to inhibit the growth of pathogenic microorganisms
