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.[1][2][3][4] The shape is typically cocci or coccobacilli.[5] Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis.[6][7] This genus of bacteria is able to grow at temperatures between −10 and 42 °C.[8] Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae.[9] The first species (Psychrobacter immobilis) was described by Juni and Heym.[10] Psychrobacter occur in wide range of moist, cold saline habitats,[8][11] but they also occur in warm and slightly saline habitats.[4][12]

Hypoacylated lipopolysaccharide (LPS) isolated from Psychrobacter cryohalolentis and Psychrobacter arcticus induces moderate TLR4-mediated inflammatory response in macrophages and such LPS bioactivity may potentially result in the failure of local and systemic bacterial clearance in patients.[13]
