Abstract

Strain CCUG 50899, a Gram-negative, rod-shaped, non-spore-forming, motile bacterium isolated from industrial environment in Sweden and tentatively assigned to the species , was studied in order to clarify its taxonomic status. 16S rRNA gene sequence similarities placed the strain in the genus , sharing highest similarity with the type strains of (99.3 %), (98.7 %), (98.6 %) and (98.5 %). The fatty acid profile of [] CCUG 50899 (major fatty acids C 7 and C cyclo 8 and presence of C 2-OH), the polar lipid profile (diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, two unknown aminolipids and an unknown phospholipid), the presence of the quinone system ubiquinone Q-10 and a polyamine pattern with the major compounds putrescine and spermidine and moderate amounts of -homospermidine supported its affiliation to the genus . DNA–DNA reassociation experiments with the type strains of its closest relatives , , and demonstrated that [] CCUG 50899 should be placed in a novel species, which is distinguishable from related species by a set of biochemical traits. Based on these data, reclassification of [] CCUG 50899 as the type strain of a novel species appears to be justified. Hence, we describe a novel species to accommodate this strain, for which we propose the name sp. nov. The type strain is CCUG 50899 (=DSM 22207).
