• The discovery of piezophiles (previously referred to as barophiles) prompted researchers to investigate the survival strategies they employ in high-pressure environments. There have been innovative high-pressure studies on biological processes applying modern techniques of genetics and molecular biology in bacteria and yeasts as model organisms. Recent advanced studies in this field have shown unexpected outcomes in microbial growth, physiology and survival when living cells are subjected to high hydrostatic pressure. The effects are conceptually dependent on the sign and magnitude of volume changes associated with any chemical reaction in the cells. Nevertheless, it is difficult to explain the pressure effects on complex metabolic networks based on a simple volume law. The challenges in piezophysiology are to discover whether the physiological responses of living cells to high pressure are relevant to their growth and to identify the critical factors in cell viability and lethality under high pressure from the general and organism-specific viewpoints.
