Abstract
A Gram-staining-negative, aerobic, motile with a single polar flagellum and rod-shaped bacterium as a bacterial host of podovirus P26218, designated IMCC26218T, was isolated from Lake Soyang, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain IMCC26218Tbelonged to the genus Rhodoferax of the family Comamonadaceae and shared 97.7-99.0 % sequence similarities with Rhodoferax species. The draft whole genome sequence of strain IMCC26218Twas ca. 4.9 Mbp in size with the DNA G+C content of 62.3 mol%. Average nucleotide identity (ANI) and digital DNA-DNA hybridisation (dDDH) values between strain IMCC26218Tand other Rhodoferax were 74.0-77.3 % and 19.5-21.0 %, respectively, showing that the strain represents a new Rhodoferax species. The strain contained summed feature 3 (C16 : 1 ω6c and/or C16 : 1 ω7c) and C16 : 0 as the major fatty acids and phosphatidylethanolamine, three unidentified phospholipids, two unidentified aminolipids and two unidentified lipids as major polar lipids. The predominant isoprenoid quinone of the strain was ubiquinone-8 (Q-8). On the basis of the phylogenetic and phenotypic characteristics, strain IMCC26218Tis considered to represent a novel species of the genus Rhodoferax, for which the name Rhodoferax lacus sp. nov. is proposed. The type strain is IMCC26218T(=KACC 18983T=NBRC 112709T).
