Genomic Analysis of Psychrophilic Prokaryotes

摘要: Psychrophilic bacteria and archaea are those adapted to low temperature (Morita 1975). The specificity of the adaptation falls at one extreme a universal growth rate/temperature relationship that largely follows Arrhenius-type kinetics (Fig. 16.1). This appears be mainly dictated by Laws Thermodynamics involve way proteins (and other biological macromolecules) behave under different temperatures (Ratkowsky et al. 2005). Psychrophily is generalized concept essentially for purpose this review incorporates microorganisms have successfully survive well conditions perpetually temperature. Many examples fall within classification manifest rate/growth features considered “extreme” adaptations. These “true” psychrophiles typified an inability grow 20–25°C may require high hydrostatic pressure growth. Cold involves alteration various specific cellular biochemistry, in particular enzyme functionality stability cell membrane lipid homeoviscosity. major hallmarks psychrophily, however,
