Abstract

Two Gram-staining-negative, aerobic, non-motile, red-pigment and rod-shaped bacterial strains, designated RSP19 and RSR28, were isolated from lake water and subjected to polyphasic taxonomic studies. Based on 16S rRNA gene sequence analysis, strains RSP19 and RSR28 exhibited 91.4–95.7 % similarity to the type strains of existing species of the genus . The species most closely related phylogenetically were (95.7 % sequence similarity), (95.4 %), (94.5 %), (94.5 %) and (94.2 %). MK-7 was the sole respiratory quinone. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and several unidentified polar lipids. The predominant fatty acids were Cω7, iso-C and iso-C 3-OH. The genomic DNA G+C contents were 34.3 and 33.9 mol% for strains RSP19 and RSR28, respectively. Based on the phenotypic characteristics, biochemical properties and genetic analysis, strains RSP19 and RSR28 clearly represent a novel species of the genus , for which the name is proposed. The type strain is RSP19 ( = CGMCC 1.14040 = KCTC 42456 = NBRC 110967).
