Psychrobacter arcticus is a Gram-negative, nonmotile species of bacteria first isolated from Siberian permafrost. Its type strain is 273-4T (=DSM 17307T =VKM B-2377T).
Hypoacylated lipopolysaccharide (LPS) from P. arcticus induces weak TLR4-mediated inflammatory response in macrophages and such LPS bioactivity may potentially result in the failure of local and systemic bacterial clearance in patients.
