Abstract

A Gram-stain negative, rod-shaped, non-motile, non-spore-forming and aerobic bacterial strain, designated HL-25, was isolated and characterized in a taxonomic study using a polyphasic approach. Comparative analysis of the 16S rRNA gene sequences showed that the isolate constituted a distinct branch within the genus , showing the highest level of 16S rRNA gene sequence similarity to HU1-GD12 (96.6 %). The major fatty acids (>10 %) of strain HL-25 were Cω7, C, summed feature 3 (comprising Cω7 and/or Cω6) and C. The major cellular hydroxy fatty acid was C 2-OH. The major isoprenoid quinone was Q-10 and the DNA G+C content was 63.8 mol%. The polar lipid profile consisted of a mixture of sphingoglycolipid, phosphatidylglycerol, phosphatidylethanolamine, phosphatidyldimethylethanolamine, diphosphatidylglycerol, an uncharacterized glycolipid, an uncharacterized aminophospholipid and four uncharacterized phospholipids. The polyamine pattern of strain HL-25 contained spermidine and putrescine. On the basis of these genotypic, chemotaxonomic and phenotypic data, strain HL-25 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is HL-25 ( = BCRC 80413 = KCTC 23953).
