Growth 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...
متن کاملAnaerobic growth of psychrophilic bacteria.
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 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...
متن کاملDiversity and association of psychrophilic bacteria in Antarctic sea ice.
The bacterial populations associated with sea ice sampled from Antarctic coastal areas were investigated by use of a phenotypic approach and a phylogenetic approach based on genes encoding 16S rRNA (16S rDNA). The diversity of bacteria associated with sea ice was also compared with the bacterial diversity of seawater underlying sea ice. Psychrophilic (optimal growth temperature, < or = 15 degre...
متن کاملEvolutionary relationships of cultivated psychrophilic and barophilic deep-sea bacteria.
Evolutionary relationships of cultivated barophilic bacteria were determined. All psychrophilic and barophilic isolates were affiliated with one of five genera of the gamma subdivision of the class Proteobacteria ((gamma)-Proteobacteria): Shewanella, Photobacterium, Colwellia, Moritella, and a new group containing strain CNPT3. The data indicate that the barophilic phenotype has evolved indepen...
