A Gram-stain-negative bacterium, designated IO390501 T , was isolated from a sea water sample from the Indian Ocean and taxonomically characterized using a polyphasic approach. The strain is phylogenetically close to ' Devosia lucknowensis ' L15 and Devosia chinhatensis IPL18 T , with 16S rRNA gene sequence similarity of 97.7 and 97.4 %, respectively. The genome of IO390501 T has a DNA G+C content of 61.9 mol% for the 3.9 Mb chromosome. Genome-based phylogenetic trees indicated that IO390501 T clusters as an independent lineage with ' D. lucknowensis ' L15. Genomic relatedness of in silico DNA-DNA hybridization between IO390501 T and phylogenetic neighbours ranged from 18.8 to 21.5 %, below the cutoff of 70 %, and corresponding average nucleotide identity values were between 71.4 and 79.0 %, lower than the 95.0 % threshold. The predominant cellular fatty acids of IO390501 T are summed feature 8 (C 18 : 1 ω7 c / C18  : 1 ω6 c ) and C 16  :  0 . IO390501 T contains ubiquinone-10 as the sole respiratory quinone, and phosphatidylglycerol and glycolipids as the major polar lipids. On the basis of the results of phenotypic, chemotaxonomic and genetic analyses, strain IO390501 T represents a novel species of the genus Devosia for which the name Devosia indica sp. nov. is proposed. The type strain is IO390501 T .

Strain IO390502 T , isolated from surface seawater in the Indian Ocean, was characterised using a polyphasic taxonomy approach. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain IO390502 T belongs to the genus Paracoccus and is closely related to Paracoccus seriniphilus DSM 14827 T (97.6%), followed by P. zeaxanthinifaciens JCM 21774 T (97.5%), P. homiensis DSM 17862 T (97.3%), P. marcusii DSM 11574 T (97.2%), P. haeundaensis BC 74171 T (97.0%) and P. carotinifaciens E-396 T (97.0%). Cells are Gram-negative, aerobic, poly-β-hydroxybutyrate-accumulating, motile, rod-shaped, and forms creamy-white colonies. Optimal growth occurred at 25-30 °C, pH 5-8, and in the presence of 3-8% NaCl. The genome of strain IO390502 T has a G+C content of 64.9 mol% and a 3.5 Mb chromosome. The in silico DNA-DNA hybridisation and average nucleotide identity values between strain IO390502 T and the three closely related taxa, P. seriniphilus DSM 14827 T , P. zeaxanthinifaciens JCM 21774 T and P. homiensis DSM 17862 T , are 19.6%, 21.9% and 20.6%, and 76.0%, 79.9% and 77.8%, respectively. Phosphatidylglycerol is the major lipid present, ubiquinone-10 (Q-10) is the sole isoprenoid quinone, and the major cellular fatty acid is C 18:1 ω7c. Based on data from phenotypic tests and genotypic differences between strain IO390502 T and its close phylogenetic relatives, strain IO390502 T represents a new species belonging to the genus Paracoccus, for which the name Paracoccus indicus sp. nov. is proposed. The type strain is IO390502 T (= JCM 32637 T  = CCTCC AB 2018071 T ).
