Study Notes
Importance in Human Health
- Many microorganisms in the digestive system of animals (like cows) aid digestion and nutrient absorption.
- Microorganisms also produce chemicals (like penicillin, tetracycline) that inhibit the growth and function of other microorganisms.
- Antibiotics are crucial for treating infections (tuberculosis, cholera) but should be used correctly.
Microorganisms in Agriculture
- Some bacteria and blue-green algae can convert atmospheric nitrogen into usable forms.
- They are called biological nitrogen fixers.
- Rhizobium bacteria are present in the root nodules of legumes and improve soil nitrogen levels.
- Some cyanobacteria perform similar nitrogen fixation in rice fields.
Immunity
- When microorganisms (bacteria or viruses) enter the body, specialized blood cells (like antibodies) recognize and destroy them.
- This response helps the body "remember" the invading organism, building immunity.
- Vaccination stimulates antibody production to build immunity against infectious diseases.
- Vaccines are suspensions or derivatives of microorganisms, inactivated or weakened.
Use in Energy/Fuel Production
- Many microorganisms create ethanol by fermenting sugars and methane in biogas reactors for fuel.
Cleaning the Environment
- Decomposers (bacteria and fungi) break down dead plants and animals to recycle nutrients.
- These nutrients (nitrogen, phosphorus, magnesium) are returned to the soil and are essential for plant growth.
