Psychrobacter arcticus

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

Psychrobacter arcticus
Scientific classification
Domain: Bacteria
Phylum: Pseudomonadota
Class: Gammaproteobacteria

P. arcticus
Binomial name
Psychrobacter arcticus
Bakermans et al. 2007

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]
