Bacterium can live in extreme conditions and general their dna can be alltered by gentic engineering. This experimental for humans organisms can vary in many characteristics and they are very resiliant in external enviromental conditions.
Extremophiles are organisms that live in places on Earth that humans would consider “extreme.” Hot spring pools, glaciers, the bottom of the ocean – these are all environments that we might have a hard time living in, but the organisms featured on these cards feel right at home there. Astrobiologists are interested in extremophiles here on Earth because they study similar environments on other planets and moons that may have extremophiles, too.
There are many categories of Bacterium throughout nature. There are some bacterias that can live in very hot conditions even in 80 or more Celcius (Thermophiles). On the other hand there are bacterium that lives in very cold conditions and called psychrophiles.
Exept the heat, there are batcerium that thriving in very acidic conditions. These kind of organisms called Acidophiles if they are surviving in toxic enviroment (<1 ph) or Alkaliphiles in the other case when ph rises more than 9.
Barophiles can live in highly pressurized places such as the bottom of the ocean floor near hot vents. Whereas most living creatures cannot survive the extreme forces that exist below the Earth’s surface and on the sea floor, these microbes thrive under high pressure.
Xerophiles can grow and reproduce in conditions with little water available.
