An orange-pigmented, short-rod-shaped, aerobic and non-motile bacterial strain, designated TK008T, was isolated from the shallow-sea hydrothermal systems off Kueishantao Island in Taiwan, China, and it was studied by using a polyphasic taxonomic approach. Cells were Gram-stain-negative, and catalase- and oxidase-positive. Strain TK008T exhibited highest 16S rRNA gene sequence similarity of 97.1 % to Paracoccus pacificus F14T. The phylogenetic trees based on 16S rRNA gene sequences showed that strain TK008T was a member of the genus Paracoccus . Digital DNA–DNA hybridization values between strain TK008T and two closely related species ( Paracoccus zhejiangensis and Paracoccus tegillarcae ) were 20.6 and 20.9 %. The average nucleotide identity values of strain TK008T compared with P. zhejiangensis and P. tegillarcae were 75.2 and 74.6 % respectively. The major isoprenoid quinone was ubiquinone-10. The predominant fatty acids (>10 %) were summed feature 8 (C18 : 1ω6c and/or C18 : 1ω7c). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unidentified phospholipids, two unidentified lipids and an unidentified glycolipid. The DNA G+C content of strain TK008T from genomic sequence data was 62.54 mol%. On the basis of polyphasic analysis, strain TK008T represents a novel species, for which the name Paracoccus aurantiacus sp. nov. is proposed. The type strain is TK008T (=CGMCC 1.13898T=JCM 33630T).

A Gram-stain-negative, rod-shaped bacterial strain, designated SW123T, was isolated from a deep-sea water sample collected from the Indian Ocean. Strain SW123T was strictly aerobic, catalase- and oxidase-positive. The predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 and summed feature 9 (comprising C16 : 0-methyl or iso-C17 : 1 ω9c). Ubiquinone-8 was the sole respiratory quinone. The major polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content was 49.4 mol%. 16S rRNA gene sequence analysis showed that strain SW123T was closely related to Aliidiomarina shirensis AIST (96.7 % sequence similarity), Aliidiomarina iranensis GBPy7T (96.3%), Aliidiomarina haloalkalitolerans AK5T (96.0%) and Aliidiomarina celeris F3105T (95.9%). Phylogenetic trees based on 16S rRNA gene sequences showed that strain SW123T represented a novel member of the genus Aliidiomarina , forming a distinct cluster with A. celeris F3105T. On the basis of phylogenetic inference and phenotypic characteristics, we propose that strain SW123T represents a novel species of the genus Aliidiomarina , with the name Aliidiomarina indica sp. nov.

Strain GJR-7T grew optimally at 30 °C, at pH 7.0–7.5 and without NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain GJR-7T clustered with the type strains of Sphingopyxis wooponensis , Sphingopyxis rigui and Sphingorhabdus planktonica , with which it exhibited 16S rRNA gene sequence similarity values of 96.0–96.3 %. Sequence similarities to the type strains of other recognized species were less than 95.5 %. Strain GJR-7T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c, 11-methyl C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) or C14 : 0 2-OH. The major polar lipids were sphingoglycolipid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and one unidentified glycolipid. The DNA G+C content of strain GJR-7T was 55.5 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, revealed that strain GJR-7T is separated from the type strains of Sphingopyxis wooponensis , Sphingopyxis rigui and Sphingorhabdus planktonica . On the basis of the data presented, strain GJR-7T is considered to represent a novel species of the genus Sphingorhabdus , for which the name Sphingorhabdus arenilitoris sp. nov. is proposed. The type strain is GJR-7T ( = KCTC 42051T = CECT 8531T). It is also proposed that Sphingopyxis wooponensis and Sphingopyxis rigui should be reclassified as members of the genus Sphingorhabdus .
