Analysis of its 16S rRNA gene sequence revealed that strain 40Bstr401T belongs to the genus Muricauda and is closely related to type strains Muricauda antarctica Ar-22T (98.2 %), Muricauda taeanensis 105T (98.2 %) and Muricauda beolgyonensis BB-My12T (97.4 %). The average nucleotide identity values for 40Bstr401T with M. antarctica Ar-22T and M. taeanensis 105T are 79.3 % and 78.8 %, respectively. The in silico DNA–DNA hybridization values between strain 40Bstr401T and M. antarctica Ar-22T and M. taeanensis 105T are 26.7 and 26.6 %, respectively. The major isoprenoid quinone of 40Bstr401T is MK-6, and iso-C17 : 0 3-OH and iso-C15 : 0 are the dominant cellular fatty acids. The major polar lipids are phosphatidylethanolamine, four unidentified amino lipids and two unidentified lipids. The G+C content of the genomic DNA is 42.9 mol%. Its phylogenetic distinctiveness and chemotaxonomic differences, together with the phenotypic properties observed in this study, indicate that strain 40Bstr401T can be differentiated from closely related species. Therefore, we propose strain 40Bstr401T represents a novel species in the genus Muricauda , for which the name Muricauda sediminis sp. nov. is suggested. The type strain is 40Bstr401T (=MCCC 1K04568T=KCTC 82139T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004757
