Abstract

Strain CMB17T 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 C18 : 1ω7c (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 CMB17T is most closely related to Paracoccus stylophorae KTW-16T (96.7 %), P. solventivorans DSM 6637T (96.4 %) and P. saliphilus YIM 90738T (96.4 %). Based on phenotypic, genotypic and phylogenetic characteristics, strain CMB17T is proposed to represent a novel species, denominated Paracoccus sediminis sp. nov. (type strain CMB17T = JCM 18467T = DSM 26170T = CGMCC 1.12681T).
