The cells of the two strains were Gram-reaction-negative and non-motile, and formed multicellular filaments. The colonies of the two strains were pink-pigmented and able to grow at 15–37 °C (optimum 25 °C) on R2A and NA medium. Strains GCR0103T and GYR3121T grew at pH 6.5–10 (optimum pH 7.5) and pH 5.5–9.5 (optimum pH 7.5), and within NaCl ranges of 0–0.4 % and 0–1 %, respectively. The polar lipid profiles of the two strains contained phosphatidylethanolamine, five unknown aminolipids, an unknown phospholipid and four or five unknown lipids. The DNA G+C contents of strains GCR0103T and GYR3121T were 56.0 and 54.5 mol%, respectively. The respiratory quinone detected in both strains was MK-7. The 16S rRNA gene sequence similarity between GCR0103T and GYR3121T was 95.5 %. The 16S rRNA gene sequence similarities of the two strains to closely related reference strains were less than 89 %. Phylogenetic analysis based on 16S rRNA genes showed that GCR0103T and GYR3121T formed a distinct phyletic line in the family Cytophagaceae . On the basis of the phenotypic, chemotaxonomic and phylogenetic properties, strains GCR0103T and GYR3121T represent two novel species in a new genus within the family Cytophagaceae , for which the names Nibrella saemangeumensis gen. nov., sp. nov. and Nibrella viscosa sp. nov. are proposed. The type strain of Nibrella saemangeumensis is GCR0103T ( = KACC 16453T = JCM 17927T) and the type strain of Nibrella viscosa is GYR3121T ( = KACC 16447T = JCM 17925T).", }
