3. Before I start -
What is the first impression for the word -
“Microbes or Microorganisms”
4. Why Microbes ?
Plague, whooping cough, diphtheria and leprosy used to kill
millions of people all over the world.
5. What would happen to these dead organisms ?
Decomposition (or rotting) is the process by which organic
material is broken down into simpler forms of matter.
6. Uses of Microorganisms
• Antibiotics and Vaccination
• Chemicals, Enzymes and other Bioactive Molecules
• Milk to Curd
• Microbes and Fermentation
• Fermented Beverages
• Microbes in sewage treatment
• Microbes in production of biogas
• Microbes as biocontrol agents
• Biological control of pests and diseases
8. Conclusion
Microorganisms can form an endosymbiotic relationship
with other, larger organisms. For example, the bacteria
that live within the human digestive system contribute to
gut immunity, synthesize vitamins such as folic acid and
biotin, and ferment complex in digestible carbohydrates.
