Genetic Adaptation of a Mevalonate Pathway Deficient Mutant in Staphylococcus aureus.

abstract：:The archaeon Thermococcus barophilus, one of the most extreme members of hyperthermophilic piezophiles known thus far, is able to grow at temperatures up to 103°C and pressures up to 80 MPa. We analyzed the membrane lipids of T. barophilus by high performance liquid chromatography-mass spectrometry as a function of pr...
