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 کاملThe role of cold-shock proteins in low-temperature adaptation of food-related bacteria.
There is a considerable interest in the cold adaptation of food-related bacteria, including starter cultures for industrial food fermentations, food spoilage bacteria and food-borne pathogens. Mechanisms that permit low-temperature growth involve cellular modifications for maintaining membrane fluidity, the uptake or synthesis of compatible solutes, the maintenance of the structural integrity o...
متن کاملCold Shock Susceptibility of Boar
F OUR trials were conducted with boar spermatozoa to determine the effects of dilution rate, seminal plasma content and extender composition on susceptibility to cold shock and the development of resistance to cold during 30 C incubation. Acrosome morphology and sperm motility were used to assess damage by cold shock. The susceptibility of boar spermatozoa to cold shock increased as the dilutio...
متن کاملFunctional conservation of cold shock domains in bacteria and higher plants.
In Escherichia coli, a family of cold shock proteins (CSPs) function as transcription antiterminators or translational enhancers at low temperature by destabilizing RNA secondary structure. A wheat nucleic acid-binding protein (WCSP1) was found to contain a cold shock domain (CSD) bearing high similarity to E. coli cold shock proteins. In the present study, a series of mutations were introduced...
متن کاملCold shock response and major cold shock proteins of Vibrio cholerae.
When exponentially growing Vibrio cholerae cells were shifted from 37 degrees C to various lower temperatures, it was found that the organism could adapt and grow at temperatures down to 15 degrees C, below which the growth was completely arrested. There was no difference between the patterns of the cold shock responses in toxinogenic and nontoxinogenic strains of V. cholerae. Gel electrophoret...
