Abstract

Three strains (JA826, JA912 and JA913), which were yellowish brown colour, rod to oval shaped, Gram-stain-negative, motile, phototrophic bacteria with a vesicular architecture of intracytoplasmic membranes, were isolated from different pond samples. The DNA G+C content of the three strains was between 64.6 and 65.5 mol%. The highest 16S rRNA gene sequence similarity of all three strains was with the type strains of the genus in the family Strain JA826 had highest sequence similarity with JA276 (98.5 %), JA737 (97.5 %) and other members of the genus (<97 %). Strain JA912 had highest sequence similarity with JA737 (99.6 %), N1 (99.3 %), ATCC 11166 (98.8 %) and less than 97 % similarity with other members of the genus . The 16S rRNA gene sequence similarity between strains JA826 and JA912 was 96.9 %. DNA–DNA hybridization showed that strains JA826 and JA912 (values among themselves and between the type strains of nearest members <44 %) did not belong to any of the nearest species of the genus . However, strains JA912 and JA913 were closely related (DNA–DNA hybridization value >90 %). The genomic distinction was also supported by differences in phenotypic and chemotaxonomic characteristics in order to propose strains JA826 (=KCTC 15478=LMG 28758) and JA912 (=KCTC 15475=LMG 28748) as new species in the genus with the names and , respectively.
