The polar lipid profile was composed of the major compounds phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified aminolipid and an unidentified polar lipid; glycolipids were not detected. The major quinone was menquinone MK-7, and the major compound in the polyamine pattern was spermidine. The predominant fatty acids were C16 : 1ω5c and C16 : 1ω7c and/or iso-C15 : 0 2-OH (detected as summed feature 3). The isolate did not contain C14 : 0 or the hydroxyl fatty acid iso-C17 : 0 3-OH found in all representatives of the genera Arcicella and Flectobacillus , but did produce C18 : 1ω7c and 11-methyl C18 : 1ω7c which are not found in these two genera. The DNA G+C content of strain E92T was 64.4 mol%. The unique 16S rRNA gene sequence, and specific chemotaxonomic and physiological data revealed that strain E92T represents a new genus in the family Cytophagaceae for which we propose the name Pseudarcicella hirudinis gen. nov., sp. nov., with the type strain of the type species as E92T ( = LMG 26720T = CCM 7988T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.037390-0
