This allocation was confirmed by analyses of the quinone system (ubiquinone Q-10), fatty acid data (major fatty acids C<jats:sub>18\u200a:\u200a1<\/jats:sub>\n                  <jats:italic>\u03c9<\/jats:italic>7<jats:italic>c<\/jats:italic> and C<jats:sub>19\u200a:\u200a0<\/jats:sub> cyclo <jats:italic>\u03c9<\/jats:italic>8<jats:italic>c<\/jats:italic>) and polar lipid profile (major components diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and unknown aminolipid AL1; moderate amounts of three unknown polar lipids, L1\u2013L3, an unknown aminolipid and an unknown aminophospholipid APL2). The polyamine pattern of Sa25<jats:sup>T<\/jats:sup> exhibited the major compound putrescine and moderate amounts of spermidine; a similar polyamine pattern with the major compound putrescine was also detected in <jats:italic>Pseudochrobactrum glaciei<\/jats:italic> KMM 3858<jats:sup>T<\/jats:sup>. DNA\u2013DNA hybridization of strain Sa25<jats:sup>T<\/jats:sup> with <jats:italic>Pseudochrobactrum glaciei<\/jats:italic> KMM 3858<jats:sup>T<\/jats:sup> and the type strains of the other <jats:italic>Pseudochrobactrum<\/jats:italic> species showed values ranging from 50.3 to 24.8\u200a%, and physiological and biochemical data clearly differentiated this isolate from the described <jats:italic>Pseudochrobactrum<\/jats:italic> species. Since Sa25<jats:sup>T<\/jats:sup> and <jats:italic>Pseudochrobactrum glaciei<\/jats:italic> KMM 3858<jats:sup>T<\/jats:sup> form a distinct lineage in the 16S rRNA gene sequence-based phylogenetic tree, and this separate position is supported by unique characteristics of their polyamine patterns and polar lipid profiles, we propose the novel genus <jats:italic>Paenochrobactrum<\/jats:italic> gen. nov., with the type species <jats:italic>Paenochrobactrum gallinarii<\/jats:italic> sp. nov.
