Evolutionary 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 independently in different (gamma)-Proteobacteria genera.
