Cold shock response and low temperature adaptation in psychrotrophic bacteria.
Psychrotrophic bacteria are capable of developing over a wide temperature range and they can grow at temperatures close to or below freezing. This ability requires specific adaptative strategies in order to maintain membrane fluidity, the continuance of their metabolic activities, and protein synthesis at low temperature. A cold-shock response has been described in several psychrotrophic bacter...
متن کاملGrowth of psychrophilic bacteria.
On the basis of the temperature range in which growth can occur, bacteria are usually divided into 3 groups, namely: thermophiles, mesophiles, and psychrophiles (sometimes called cryophiles or rhigophiles). Thermophiles have temperature optima (generally quite close to temperature maxima) 10 to 25 degrees above the temperature optima of mesophiles. Thermophiles and mesophiles are easily disting...

Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...
متن کاملTemperature adaptability of psychrotrophic Pseudomonas.
The rate of oxidation of glucose and alanine at low temperatures by washed cells of psychrotrophic strains of Pseudomonas is related to growth temperature.
متن کاملPosttranscriptional modification of tRNA in psychrophilic bacteria.
Posttranscriptional modification in tRNA is known to play a multiplicity of functional roles, including maintenance of tertiary structure and cellular adaptation to environmental factors such as temperature. Nucleoside modification has been studied in unfractionated tRNA from three psychrophilic bacteria (ANT-300 and Vibrio sp. strains 5710 and 29-6) and one psychrotrophic bacterium (Lactobacil...
