Limnovirga soli gen. nov., sp. nov., isolated from river sediment

A cream-coloured, Gram-stain-negative, rod-shaped bacterium, designated strain KSC-6^T, was isolated from soil sampled at the Gapcheon River watershed in Daejeon, Republic of Korea. The organism does not require NaCl for growth and grows at pH 6.0-8.0 (optimum, pH 7.0) and 10-37 °C (optimum, 25 °C). Phylogenetic trees based on the 16S rRNA gene sequences reveal that strain KSC-6^T belongs to the family Chitinophagaceae within the order Chitinophagales and is most closely related to Panacibacter ginsenosidivorans Gsoil 1550^T (95.9% similarity). The genomic DNA G+C content was 38.9 mol%. The major cellular fatty acids (>8 %) of strain KCS-6^T were iso-C_15:0, iso-C_15 : 1 G and iso-C_17 : 0 3-OH. The predominant respiratory quinone was menaquinone 7 and the predominant polar lipids were phosphatidylethanolamine, five unidentified aminolipids and two unidentified lipids. Based on genome analyses, low digital DNA-DNA hybridization, average nucleotide identity and average amino acid identity values with closely related genera, and differential chemotaxonomic and physiological properties, we suggest that strain KCS-6^T represents a novel species in a new genus in the family Chitinophagaceae, for which the name Limnovirga soli gen. nov., sp. nov. (type strain KCS-6^T=KCCM 43337^T=NBRC 114336^T) is proposed.
