Phenotypic, chemotaxonomic and phylogenetic analyses established affiliation of the isolate to the genus Dyadobacter . Cells occurred in pairs in young cultures but became chains of coccoid cells in old cultures, and produced a flexirubin-like yellow pigment. Strain L-1T could not hydrolyse cellulose, and had a DNA G+C content of 51.3 mol%. The major cellular fatty acids were iso-C15 : 0, C16 : 1ω5c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). C16 : 0, iso-C15 : 0 3-OH and C16 : 0 3-OH were the other major fatty acid components. Comparative 16S rRNA gene sequence analysis showed that strainL-1T was most closely related to Dyadobacter fermentans DSM 18053T (99.2 %), Dyadobacter soli JCM 16232T (98.9 %) and Dyadobacter beijingensis CGMCC 1.6375T (98.7 %). However, the new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to JCM 16232T (41.2±1.8 %), DSM 18053T (38.6±2.6 %) and CGMCC 1.6375T (35.0±2.1 %). Strain L-1T could also be differentiated from its closest phylogenetic relatives based on differences in several phenotypic characteristics. These data suggest that strain L-1T represents a novel species of the genus Dyadobacter , for which the name Dyadobacter jiangsuensis sp. is proposed. The type strain is L-1T (DSM 29057T = CGMCC 1.12969T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000069
