A Gram-stain-negative bacterium, designated strain 40Bstr34 T , isolated from a sediment sample from the West Pacific Ocean, was taxonomically characterized by using a polyphasic approach. The strain was phylogenetically close to Jiella aquimaris LZB041 T and Jiella endophytica CBS5Q-3 T , with 16S rRNA gene sequence similarities of 98.5 and 97.1 %, respectively. The genome of strain 40Bstr34 T featured a G+C content of 65.7 % for a 5.8 Mb chromosome. Up-to-date bacterial core gene set analysis revealed that strain 40Bstr34 T represents one independent lineage with J.aquimaris LZB041 T . In silico DNA-DNA hybridization values between strain 40Bstr34 T and its phylogenetic neighbours ranged from 30.3-34.2 %, below the cutoff of 70 %. In addition, the corresponding average nucleotide identity values were between 81.8-83.7 %, which are lower than 95 % threshold. The predominant cellular fatty acids of strain 40Bstr34 T were summed feature 8 (C 18 : 1   ω 6c and/or C 18 : 1   ω 7c ), cyclo-C 19 : 0   ω8 c and iso-C 17 : 0 3-OH, and ubiquinone-10 as the predominant respiratory quinone. The major polar lipids included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, two unidentified aminolipids and two unidentified lipids. Based on the results of phenotypic, chemotaxonomic and genetic analyses, strain 40Bstr34 T is identified as representing a novel species of the genus Jiella for which the name Jiella pacifica sp. nov. is proposed. The type strain is 40Bstr34 T (=JCM 33903 T =MCCC 1K04569 T ).

A Gram-stain-negative bacterium, designated strain 501str8 T , was isolated from a sediment sample collected from the East Pacific Ocean. 16S rRNA gene sequence analysis revealed that strain 501str8 T belonged to the genus Muricauda , with closely related type strains Muricauda aquimarina SW-63 T (98.5 %), Muricauda lutimaris SMK-108 T (98.3 %) and Muricauda ruestringensis B1 T (97.9 %). Up-to-date bacterial core gene set analysis revealed that strain 501str8 T represented one independent lineage with M. aquimarina SW-63 T . The average nucleotide identity values of strain 501str8 T with M. aquimarina SW-63 T and M. lutimaris SMK-108 T were 80.2 and 81.3 %, respectively. In silico DNA-DNA hybridization values between strain 501str8 T and M. aquimarina SW-63 T and M. lutimaris SMK-108 T were 22.8 and 32.9 %, respectively. The predominant isoprenoid quinone was menaquinone-6, and iso-C 15 : 0 , iso-C 17 : 0 3-OH and iso-C 15 : 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 501str8 T could be differentiated from closely related species. Therefore, we propose that strain 501str8 T represents a novel species of the genus Muricauda , for which the name Muricauda oceani sp. nov. is suggested. The type strain is 501str8 T (=JCM 33902 T =MCCC 1K04567 T ).
