Abstract
A Gram-stain-negative bacterium, designated strain 501str8T, was isolated from a sediment sample collected from the East Pacific Ocean. 16S rRNA gene sequence analysis revealed that strain 501str8T belonged to the genus
Muricauda
, with closely related type strains
Muricauda aquimarina
SW-63T (98.5 %),
Muricauda lutimaris
SMK-108T (98.3 %) and
Muricauda ruestringensis
B1T (97.9 %). Up-to-date bacterial core gene set analysis revealed that strain 501str8T represented one independent lineage with
M. aquimarina
SW-63T. The average nucleotide identity values of strain 501str8T with
M. aquimarina
SW-63T and
M. lutimaris
SMK-108T were 80.2 and 81.3 %, respectively. In silico DNA–DNA hybridization values between strain 501str8T and
M. aquimarina
SW-63T and
M. lutimaris
SMK-108T were 22.8 and 32.9 %, respectively. The predominant isoprenoid quinone was menaquinone-6, and iso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 1 G were the dominant cellular fatty acids. The G+C content of the genomic DNA was 42.8 mol%. Differential phylogenetic distinctiveness and chemotaxonomic differences, together with the phenotypic properties observed in this study, revealed that strain 501str8T could be differentiated from closely related species. Therefore, we propose that strain 501str8T represents a novel species of the genus
Muricauda
, for which the name Muricauda oceani sp. nov. is suggested. The type strain is 501str8T (=JCM 33902T=MCCC 1K04567T).
