Abstract

Two non-motile, Gram-staining-negative, yellow-pigmented bacterial strains designated HMD1001 and HMD1033 were isolated from the water of a mesotrophic artificial lake in Korea. A phylogenetic tree based on 16S rRNA gene sequences indicated that both strains could be assigned to the genus ; strain HMD1001 appeared most closely related to H7 (96.8 % sequence similarity), DSM 4002 (96.6 %) and DSM 2063 (96.6 %) whereas strain HMD1033 appeared most closely related to LMG 2201 (96.2 %), AT1048 (96.2 %) and AT1042 (96.2 %). The major fatty acids of strain HMD1001 were iso-C (21.5 %), summed feature 3 (comprising Cω6 and/or Cω7; 18.0 %) and iso-C G (7.6 %), whereas those of HMD1033 were summed feature 3 (23.8 %), iso-C 3-OH (16.9 %), iso-C (15.3 %) and anteiso-C (12.1 %). The genomic DNA G+C contents of strains HMD1001 and HMD1033 were 35.9 and 32.2 mol%, respectively. Phylogenetic and phenotypic evidence indicates that strains HMD1001 and HMD1033 represent two novel species of the genus , for which the names sp. nov. (type strain HMD1001  = KCTC 22796  = CECT 7594) and sp. nov. (type strain HMD1033  = KCTC 22825  = CECT 7649) are proposed.
