Cells were Gram-staining-negative, aerobic, non-sporulating rods, motile by means of a polar flagellum, and formed white round colonies. The strain grew at the range of 10–40 °C (optimum, 28–30 °C), pH 6.0–10.0 (optimum 7.0–8.0) and 0–1 % NaCl. The 16S rRNA gene sequence analysis showed the relatedness of S-12T to Phreatobacter stygius YC6-17T (98.2 %) and Phreatobacter oligotrophus PI_21T (98.1 %). The major respiratory quinone was ubiquinone Q-10. Polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and an unidentified lipid. The major fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The DNA G+C content was 69.3 mol%. On the basis of its differences from species of the genus Phreatobacter with validly published names, strain S-12T is identified as representing a novel species, for which the proposed name is Phreatobacter cathodiphilus sp. nov., with S-12T as the type strain (=KACC 18497T=JCM 31612T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002904
