Strain HJM-2T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain HJM-2T belonged to the genus Algoriphagus, clustering coherently with the type strain of A. taiwanensis. Strain HJM-2T exhibited 16S rRNA gene sequence similarities of 98.6 and 97.2 % to A. taiwanensis CC-RR-82T and A. boseongensis BS-R1T, respectively, and 92.7–96.7 % to the type strains of the other species of the genus Algoriphagus. Strain HJM-2T contained MK-7 as the predominant menaquinone and iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain HJM-2T were phosphatidylcholine, phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain HJM-2T was 45 mol% and mean DNA–DNA relatedness values with the type strains of A. taiwanensis and A. boseongensis were 10–19 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain HJM-2T is separated from recognized species of the genus Algoriphagus. On the basis of the data presented, strain HJM-2T represents a novel species of the genus Algoriphagus, for which the name Algoriphagus confluentis sp. nov. is proposed. The type strain is HJM-2T ( = KCTC 42704T = NBRC 111222T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000686
