Names Psychromonas ingrahamii 37
Accession numbers NC_008709
Background Psychromonas ingrahamii strain 37 is a non-motile, psychrophilic, heterotrophic Gram-negative bacterium phylogenetically associated with the gamma subdivision of the Proteobacteria. P. ingrahamii was isolated from sea ice core collected from Point Barrow in northern Alaska. This organism is large, rod-shaped, and contains gas vacuoles of two distinct morphologies. It grows well at NaCl concentrations from 1 to 10 % and at temperatures from -12 to 10 degrees Celsius. Phylogenetic analyses of 16S rRNA gene sequences indicate that this bacterium is closely related to members of the genus Psychromonas, with highest sequence similarity (96.8 %) to Psychromonas antarctica. Phenotypic analyses differentiate strain 37 from P. antarctica on the basis of several characteristics, including cell morphology, growth temperature range and the ability to hydrolyse polymers. DNA-DNA hybridization experiments reveal a level of relatedness of 37 % between strain 37 and P. antarctica, providing further support that it represents a distinct species. This organism will provide information on adaptation to extreme cold. (EBI Integr8)
