| Abstract | A Gram-stain-negative, mucus-forming, motile by gliding, non-spore-forming and short rod-shaped bacterial strain designated R1-15T was isolated from soil and its taxonomic position was evaluated using a polyphasic approach. Strain R1-15T grew at 15–37°C (optimum, 30°C), at pH 6–7 (optimum, pH 6) and in the presence of 0–1% (w/v) NaCl (optimum, 0%) on 0.1X TSA. On the basis of 16S rRNA gene sequence similarity, the novel strain was assigned to the family Chitinophagaceae of the phylum Bacteroidetes, and its closest related taxa were species of the genera Taibaiella (88.76– 90.02% sequence similarity), Lacibacter (89.24–90.00%), Chitinophaga (88.61–89.76%), and Terrimonas (89.04%). Flexirubin- type pigments were produced. The only isoprenoid quinone was MK-7, and the major polar lipid was phosphatidylethanolamine. Based on whole genome comparisons between the strain R1-15T and the type strains of relatives, the orthologous average nucleotide identity values were 66.9– 67.0%. The DNA G+C content of strain R1-15T was 43.8 mol%. The combination of phylogenetic, chemotaxonomic and phenotypic data clearly supported separation of strain R1-15T from related taxa, and thus the name Mucibacter soli gen. nov., sp. nov. is proposed. The type strain is R1-15T (= KCTC 62274T = JCM 31190T). |
