Psychrobacter arcticus explained

Psychrobacter arcticus is a Gram-negative, nonmotile species of bacteria^[1] first isolated from Siberian permafrost. Its type strain is 273-4^T (=DSM 17307^T =VKM B-2377^T).

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.^[2]
