Abstract

A Gram-staining-negative, rod-shaped, red strain, HME8457, was isolated from a freshwater stream located in the Republic of Korea. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME8457 formed a lineage within the genus . Strain HME8457 was most closely related to species of the genus : Dae 13 (96.4 % sequence similarity), DS-40 (95.3 %), DS-45 (94.9 %), 1-2 (94.2 %) and ‘’ HME6451 (93.6 %). The major fatty acids were iso-C (28.8 %), summed feature 3 (comprising Cω6 and/or Cω7; 21.7 %), iso-C 3-OH (7.7 %) and anteiso-C (6.2 %). The only respiratory quinone was MK-7. Polar lipid analysis revealed the presence of phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids. Sphingolipid was present. The DNA G+C content was 33.3 mol%. On the basis of the evidence presented in this study, strain HME8457 represents a novel species of the genus , for which the name sp. nov. is proposed; the type strain is HME8457 ( = KACC 17312 = CECT 8291).
