title: Flavisolibacter rigui sp. nov., isolated from freshwater of an artificial reservoir and emended description of the genus Flavisolibacter.
abstract: A non-motile and rod-shaped bacterium, designated strain 02SUJ3(T), was isolated from freshwater collected from the Juam Reservoir (Republic of Korea). Cells were Gram-stain-negative, aerobic, oxidase-negative and catalase-positive. The major fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The strain contained MK-7 as the major isoprenoid quinone. The main polar lipid was phosphatidylethanolamine. The DNA G+C content was 46.4 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain 02SUJ3(T) forms an independent lineage within the genus Flavisolibacter with low sequence similarity to Flavisolibacter ginsengiterrae Gsoil 492(T) and Flavisolibacter ginsengisoli Gsoil 643(T) (95.7 %). Phenotypic characteristics distinguished strain 02SUJ3(T) from members of the genus Flavisolibacter. On the basis of the evidence presented in this study, strain 02SUJ3(T) is considered to represent a novel species, for which the name Flavisolibacter rigui sp. nov. is proposed. The type strain is 02SUJ3(T) ( = JCM 17515(T) = KCTC 23328(T)). An emended description of the genus Flavisolibacter is also provided.
