Microorganisms in Daily Life
Microbes in our every day life
Microorganisms or microbes are very tiny one-celled microscopic organisms and are found everywhere in the world. They are found in all living things. There are more microbes on and inside our body than the cells. They can live in the air, on land surface and salt water environments. Some of them (pathogens) can be harmful and case diseases but there are also some microbes which are needed for the survival of the living things. Microorganisms can enter the air through human or animals sneezings and dust particles. Microorganisms that grow in the mucus of the respiratory tract enter the air with moisture particles which are sneezed out of the lungs and are breathed in the lungs of others and cause sickness.
Microorganisms also fertilize soil and help grow plants. Microbes sticking to the roots of plants help decompose dead organic matters into food for the plants. Some of them causes illness to human, animals and plants but others kill the harmful bacteria, keep them safe from disease and help happy living for them. Drug companies make use of hundreds of different microorganisms to make medicines which help cure disease. Human waste can be made safer particles by microorganisms. Scientists all over the world are always looking for new ways to use microbes.
Most of us have misconception about microorganisms and think that it would be a great achievement of scientists if they could wipe out all the microorganisms. But we never think about the useful side of the microbes. Microorganisms do more good than harms and are beneficial for human beings. We are little informed about the usefulness of microbes in our day-to-day life. So let us look into some specific examples about the usefulness of microbes in our life:
· Bacillus thuringiensis is common soil bacterium which acts as a natural pest-killer in gardens and on crops.
· The bacterium Propionibacterium freudenreichii produces carbon dioxide gas (CO2) bubbles that burst in ripening cheese...
