psychrobacter cryohalolentis psychrobacter cryohalolentis psychrobacter cryohalolentis is a gram-negative, nonmotile species of bacteria. it was first isolated from siberian permafrost. its type strain is k5t (=dsm 17306t =vkm b-2378t). psychrobacter cryohalolentis scientific classification domain: bacteria phylum: pseudomonadota class: gammaproteobacteria order: pseudomonadales family: moraxellaceae genus: psychrobacter species: p. cryohalolentis binomial name psychrobacter cryohalolentisbakermans et al. 2007 hypoacylated lipopolysaccharide (lps) from p. cryohalolentis 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.
