Abstract

Two Gram-staining-negative, orange coloured, non-motile, rod-shaped bacterial strains, designated strains IMCC26013 and IMCC26026, were isolated from a freshwater sample collected from Lake Soyang in Korea. The 16S rRNA gene-based phylogenetic analyses showed that both strains belonged to the genus and that strains IMCC26013 and IMCC26026 were most closely related to (96.5 %) and (97.7 %), respectively. DNA G+C contents of strains IMCC26013 and IMCC26026 were 37.8 and 33.7 mol%, respectively. DNA–DNA relatedness between strain IMCC26026 and HMD1033 was 56.4 %, showing a novel species status of strain IMCC26026. Major fatty acid constituents (>10 %) of strain IMCC26013 were iso-C G, C 6, C 6 and summed feature 3 (C 6 and/or C 7) and those of strain IMCC26026 were iso-C, anteiso-C and summed feature 3. Respiratory quinone detected in the two strains was MK-6. Both strains contained phosphatidylethanolamine as a major polar lipid. On the basis of these results, strains IMCC26013 and IMCC26026 were considered to represent novel species in the genus , for which the names (type strain IMCC26013=KCTC 52573=NBRC 112526), and (type strain IMCC26026=KCTC 52572=NBRC 112527) are proposed, respectively.
