Isolates were facultatively anaerobic, Gram-stain-negative, rod-shaped, motile by means of a single polar flagellum, and they did not produce bacteriochlorophyll α. Cells grew in tryptic soy broth with 0–5.5 % (w/v) NaCl, at 4–55 °C and pH 3.5–10.5. Isolates were positive for catalase, oxidase, urease, Voges–Proskauer test, gelatin hydrolysis and H2S production. Analysis of 16S rRNA gene sequences indicated that the closest relatives of strains Q4.6T and Q2.11 were the type strains Labrenzia suaedae DSM 22153T (97.4 %), Pannonibacter phragmitetus DSM 14782T (96.9 and 97.0 %) and Pannonibacter indicus DSM 23407T (96.8 %). The genomic average nucleotide identity (ANI) value for Q4.6T and Q2.11 was 100 %; however, this value was less than 77.7 % for the type strains P. phragmitetus and P. indicus , and less than 74.0 % for the type strain L. suaedae . The cellular fatty acid profile of strains Q4.6T and Q2.11 consisted primarily of C18 : 1ω7c. The principal quinone of the isolates was Q-10. The polar lipid profile consisted of diphosphatidyl glycerol, phosphatidyl glycerol, phosphatidyl ethanolamine and phosphatidyl choline. On the basis of phylogenetic analysis, genomic ANI analysis, DNA–DNA hybridization results, as well as phenotypic and chemotaxonomic data, strains Q4.6T and Q2.11 are assigned as a novel species within the genus Pannonibacter . The type strain is Pannonibacter carbonis Q4.6T (=CGMCC 1.15703T=KCTC 52466T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002794
