Psychrobacter is a genus of Gram-negative, osmotolerant, oxidase-positive, psychrophilic or psychrotolerant, aerobic bacteria which belong to the family Moraxellaceae and the class Gammaproteobacteria. The shape is typically cocci or coccobacilli. Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis. This genus of bacteria is able to grow at temperatures between −10 and 42 °C. Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae. The first species was described by Juni and Heym. Psychrobacter occur in wide range of moist, cold saline habitats, but they also occur in warm and slightly saline habitats.
Psychrobacter aquimaris is a Gram-negative, non-spore-forming, nonmotile bacterium of the genus Psychrobacter which was isolated from the South Sea in Korea.
Psychrobacter arenosus is a Gram-negative, psychrotolerant, aerobic, nonmotile bacterium of the genus Psychrobacter, which was isolated from coastal sea ice and sediment samples of the Sea of Japan.
Psychrobacter okhotskensis is a Gram-negative, catalase- and oxidase-positive, aerobic, facultatively psychrophilic, nonmotile bacterium of the genus Psychrobacter, which was isolated from seawater of the Monbetsu coast of the Okhotsk Sea in Hokkaido in Japan.
Psychrobacter phenylpyruvicus is a Gram-negative, catalase- and oxidase-positive, nonmotile bacterium of the genus Psychrobacter, which was isolated from human blood in Belgium. Psychrobacter phenylpyruvicus can cause humans infections such as endocarditis, peritonitis, and fungating lesion of the foot, but those infections caused by this bacterium are rare.
Psychrobacter piscatorii is a Gram-negative, catalase- and oxidase-positive, psychrotolerant, nonmotile bacterium of the genus Psychrobacter, which was isolated from a fish-processing plant. The temperature where Psychrobacter piscatorii was isolated was about 8 °C.
