摘要: We observed physiological and metabolic activity of Shewanella oneidensis strain MR1 Escherichia coli MG1655 at pressures 68 to 1680 megapascals (MPa) in diamond anvil cells. measured biological formate oxidation high (68 1060 MPa). At 1200 1600 MPa, living bacteria resided fluid inclusions ice-VI crystals continued be viable upon subsequent release ambient (0.1 Evidence microbial viability these extreme expands by an order magnitude the range conditions representing habitable zone solar system.
