Barophile
From Wikipedia, the free encyclopedia
Barophiles are bacteria which live in high pressure environments. They are generally found on ocean floors, where pressure generally exceeds 380 atm (38 MPa). Some have been found at the bottom of the Pacific Ocean where the maximum pressure is roughly 117 MPa.
Obligate barophiles cannot survive outside of such environments. For example, the Pseudomonas species P. bathecetes requires a pressure of 1000 atm (100 MPa) and a temperature of 3 degrees Celsius. Barotolerant bacteria are able to survive at high pressures, but can exist in less extreme environments as well.
Barophiles grow in darkness, and so are very uv sensitive, they lack many mechanisms of DNA repair.
