Bacteria in simple words are the ubiquitous organisms that cannot be seen by naked eyes. They are all around us , on our body and inside our body.
Microbiologist use a more appropriate and scientific language and call it as prokaryot .That is they don't have fully differentiated nucleus and rarely possess membrane bound organelles .
Many of us usually come across da word bacteria with reference to some disease or infections etc. and rarely go into deeper science of wht tht organism actually is.
Many of us like curd , and it is so interesting that there is a very important role of bacteria in its formation (Lactic acid bacteria).
Bacteria are found almost everywhere ,those which are found in extreme environments are called as extremophiles.
They can occur at very high temperature (thermophiles) as well as very cold areas too.
Temperatures in Hydrothermal vents can reach even 350-360 degrees(boiling point of water is 100 degrees). These tiny organisms have known to occur even at temperatures of 113 degrees (hyperthermophile). The presence of these organisms at such high temperatures and in the regions of hydrothermal vent could give a clue about the past life on earth.
Their major importance lies in their role in oceanic food chain . Acting as decomposers, they break down the organic matter , once the organism is dead.
Marine bacteria have also gained importance for the antibiotics.
