Optimal growth occurred at 40 °C, pH 7.5 and with 7.0 % (w/v) NaCl. Q-10 was the sole respiratory quinone. The major cellular fatty acids (>10.0 %) in WDN1C137T were C18 : 1ω7c (46.2 %), cyclo C19 : 0ω8c (18.7 %) and C16 : 0 (12.3 %). The major polar lipids were phosphatidylglycerol, phosphoglycolipid, phosphatidylcholine, one unidentified glycolipid, one unidentified lipid, one unidentified aminolipid and two unidentified phospholipids. The genomic DNA G+C content was 70.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that WDN1C137T shared the highest similarity (94.5 %) to Roseivivax jejudonensis KCTC 42110T, followed by Roseivivax halodurans JCM 10272T (94.2 %) and Roseivivax roseus DSM 23042T (94.1 %). WDN1C137T formed a separate branch from the closely related genera Roseivivax , Loktanella , Paracoccus and Cribrihabitans within the family Rhodobacteraceae , which indicated that it represented a novel genus in the phylogenetic tree. On the basis of the data from the current polyphasic study, the isolate is proposed to represent a novel species of a novel genus within the family Rhodobacteraceae , with the name Rhodosalinus sediminis gen. nov., sp. nov. The type strain of the type species is WDN1C137T (=KCTC 52478T=MCCC 1H00170T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002424
