The importance uses of micro organisms

Microbes are the foundation of life as they’re everywhere. They are in the air we breathe, in the food we eat, in the ground we walk on and even inside us. There are more microbes on a person’s hand than there are people on the entire earth.

Microorganisms are by dictionary definition ‘microscopic organisms’. They do many jobs in an extremely wide field. Without them the planet wouldn’t survive, as we know it. We couldn’t digest our food, neither of course could animals, plants couldn’t grow, rubbish and waste wouldn’t decay and there would be a lot less oxygen in the air we breathe. Many people believe they were the very start of life, the start of evolution, which in turn led to humans, you and me. Microorganisms can be split into different groups, each with their own characteristics and ‘jobs’. There are Bacteria, Fungi, Protozoan and Viruses (although some people believe that viruses are not alive.)

Bacteria are a simple one-cell organism, measuring on average from 0.3 to 2 microns (0.001mm) in diameter and can been seen through a microscope. They are classified as prokaryotes. Bacteria are amazing organisms, when most people think of bacteria they think of disease and contamination. In reality bacteria can cause human and animal disease but they are also extremely important because of their immense flexibility of modification, easy reproduction and rapid growth. Bacteria have been around for millions of years and some of the oldest fossils are of bacteria-like organisms. This indicates they were the foundation of life.

Some bacteria live symbiotically in the guts of humans and animals to help with digestion and to aid with the destruction of harmful organisms. They can produce some vitamins needed for the body. Bacteria are also very important to plants as they help to convert nitrogen into a usable form.

They play a vital role in recycling carbon and sulphur and other chemical basics. Bacteria help to decompose animal waste, dead organisms into chemical elements. Some bacteria will reverse this and turn chemical elements into a different form that can then be used by animals and plants. Various bacteria are ...
