MICROORGANISMS AND THEIR IMPACT IN OUR LIVES.
We almost always presume that microorganisms are harmful to us. So this is because we read about how they cause diseases to both plants and animals including human. But, it is actually a fact that microorganisms are useful to us in many ways. Microorganisms help in the production of many food items, making medicines, keeping the environment clean, in manufacturing and in research. Let us learn about microorganisms and their uses.
Join me as I take you through how this invisible organisms helps us in living.
- ALCOHOLIC Drinks:
Alcoholic drinks are prepared or manufactured by the process of fermentation. Each drink is derived from a different starting product such as potato and grapes. Then it is fermented, distilled and alcohol is prepared. The commonly used microorganism here is different types of fungus like yeast. Some even use bacteria and fungus. Alcoholic drinks include wine, rum, vodka etc.
- ORGANIC ACIDS:
Organic acids are commercially prepared using fungi. Acetobacter, Rhizopus, Penicillium are a few fungi that are used to ferment substrates such as fruits and sugar-containing syrups. Examples of acids that are derived and manufactured on a large scale using fungi are acetic acid, citric acid, gluconic acid, fumaric acid and lactic acid.
- ENZYMES:
Many microbes are used in the derivation of enzymes such as lipase, lactase, protease, peptidase to name a few.
- STEROID PRODUCTION:
Some bacterial and fungal species are used in the preparation of steroids that are then injected into the human body for different purposes.
- HELP IN SEWAGE TREATMENT:
Not only are microorganisms helpful to our body, they are also helpful to the environment. They help in the secondary treatment stage of sewage treatment.
- Used as insecticides:
Certain bacterial and fungal species are used to keep certain insects and pests away from crops.
