Strain CMB17(T) was a short rod-shaped bacterium isolated from marine sediment of the Pacific Ocean. Cells were Gram-stain-negative and non-motile. Optimal growth occurred at 25-30 °C, pH 6.5-7 and 0.5-1% (w/v) NaCl. The major fatty acid was C(18 : 1)ω7c (87.59%), and ubiquinone-10 was detected as the only isoprenoid quinone. The DNA G+C content of the genomic DNA was 62.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CMB17(T) is most closely related to Paracoccus stylophorae KTW-16(T) (96.7%), P. solventivorans DSM 6637(T) (96.4%) and P. saliphilus YIM 90738(T) (96.4%). Based on phenotypic, genotypic and phylogenetic characteristics, strain CMB17(T) is proposed to represent a novel species, denominated Paracoccus sediminis sp. nov. (type strain CMB17(T) = JCM 18467(T) = DSM 26170(T) = CGMCC 1.12681(T)).
