Temperature-dependent pattern of heat shock protein synthesis in psychrophilic and psychrotrophic microorganisms
The patterns of proteins synthesized by the arctic psychrophilic bacterium Res-10 and the psychrotroph Bacillus psychrophilus during various heat shocks up to 32 °C were examined. Both microorganisms were found to display temperature-dependent patterns of heat shock protein synthesis. Elevation of t...

The patterns of proteins synthesized by the arctic psychrophilic bacterium Res-10 and the psychrotroph Bacillus psychrophilus during various heat shocks up to 32 °C were examined.
