Abstract

A Gram-stain-negative, rod-shaped and red-pigmented strain, HME7025, was isolated from freshwater sampled in the Republic of Korea. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain HME7025 formed a lineage within the family of the phylum . Strain HME7025 was closely related to the genera , and The 16S rRNA gene sequence similarity values of strain HME7025 were under 94.5 % to its closest phylogenetic neighbours. The major fatty acids of strain HME7025 were iso-C (41.9 %), summed feature 3 (comprising Cω7 and/or Cω6; 12.2 %) and anteiso-C (10.8 %). The major respiratory quinone was menaquinone-7. The major polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids and one unidentified polar lipid. The DNA G+C content of strain HME7025 was 37.9 mol%. On the basis of the evidence presented in this study, strain HME7025 represents a novel species of a novel genus within the family , for which the name gen. nov., sp. nov. is proposed. The type strain is HME7025 (=KCTC 23617=CECT 7957).
