A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).

The Gram-strain-negative, rod-shaped, facultatively anaerobic, non-motile bacterial strain, designated S1-10T, was isolated from marine sediment. Strain S1-10T grew at 4–42 °C (optimally at 30–35 °C), at pH 7.0–10 (optimally at pH 9) and in the presence of 0.5–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S1-10T was related to the genus Aequorivita and had highest 16S rRNA gene sequence similarity to Aequorivita viscosa 8-1bT (97.7%). The predominant cellular fatty acids were iso-C15 : 0 and anteiso-C15 : 0. The main respiratory quinone was menaquinone 6 (MK-6). The genomic DNA G+C content of strain S1-10T was 34.6 mol%. The polar lipid profile of strain S1-10T contained phosphatidylethanolamine, two aminolipids, two glycolipids, one phosphoglycolipid and three unidentified polar lipids. In addition, the maximum values of in silico DNA–DNA hybridization (isDDH) and average nucleotide identity (ANI) between strain S1-10T and A. viscosa CGMCC 1.11023T were 15.4 and 75.7 %, respectively. Combined data from phenotypic, phylogenetic, isDDH and ANI analyses demonstrated that strain S1-10T is the representative of a novel species of the genus Aequorivita , for which we propose the name Aequorivita sinensis sp. nov. (type strain S1-10T=CGMCC 1.12579T=JCM 19789T). We also propose that Vitellibacter todarodis and Vitellibacter aquimaris should be transferred into genus Aequorivita and be named Aequorivita todarodis comb. nov. and Aequorivita aquimaris comb. nov., respectively. The type strain of Aequorivita todarodis comb. nov. is MYP2-2T (= KCTC 62141T= NBRC 113025T) and the type strain of Aequorivita aquimaris comb. nov. is D-24T (=KCTC 42708T=DSM 101732T).

A novel Gram-stain-positive bacterium, designated strain YIM M11385T, was isolated from a marine sediment sample collected from the South Bay, Little Andaman Island, India with a salinity of 35 p.p.m., pH 8.5. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM M11385T belongs to the genus Marininema , supported by a bootstrap value of 100 %. The taxonomic position of this organism was further established by using a polyphasic approach. Strain YIM M11385T grew optimally at 28 °C, pH 7.0 and in the presence of 0–5 % (w/v) NaCl. The 16S rRNA gene sequence similarity between strain YIM M11385T and Marininema mesophilum SCSIO 10219T was 98.3 %. Strain YIM M11385T exhibited a quinone system with only MK-7, the polar lipid profile included diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major components, and the major fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The level of DNA–DNA relatedness between strain YIM M11385T and M. mesophilum SCSIO 10219T was 59.36 %. On the basis of genotypic and phenotypic data, it is apparent that strain YIM M11385T represents a novel species of the genus Marininema , for which the name Marininema halotolerans sp. nov. is proposed. The type strain is YIM M11385T ( = CCTCC AB 2012052T = DSM 45789T). In addition, we propose that the description of the genus Marininema should be further emended based on the results of the present study.

Strain WT-MW11T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain WT-MW11T was similar to those of P. ferrugineus JCM 20687T and P. aquimaris HDW-19T. The DNA G+C content of strain WT-MW11T was 61.6 mol% and its mean DNA–DNA relatedness value with P. ferrugineus JCM 20687T was 12.3 %. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WT-MW11T was distinguishable from the two recognized species of the genus Pseudorhodobacter . On the basis of the data presented, strain WT-MW11T is considered to represent a novel species of the genus Pseudorhodobacter , for which the name Pseudorhodobacter wandonensis sp. nov. is proposed. The type strain is WT-MW11T ( = KCTC 23672T = CCUG 61506T). The description of the genus Pseudorhodobacter is emended.

An aerobic, Gram-stain-negative, motile, rod or long-rod-shaped bacterial isolate, strain MK6-18T, was isolated from a marine sediment sample from Kongsfjorden, Arctic. The bacterium grew optimally at 20 °C, pH 7.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MK6-18T belonged to the genus Roseovarius . Its closest phylogenetic neighbour was Roseovarius nanhaiticus NH52JT showing 96.97 % 16S rRNA gene sequence similarity. The genome of strain MK6-18T is 4.2 Mb long in size with a G+C content of 59.5 mol%. The average nucleotide identity value between the genomes of strain MK6-18T and Roseovarius nanhaiticus NH52JT, was 78.0 %. Similar to other species of the genus Roseovarius , strain MK6-18T had ubiquinone 10 as the predominant ubiquinone and C12 : 0, C16 : 0, summed feature 3 (C16 : 1ω7c/ω6c) and summed feature 8 (C18 : 1ω7c/ω6c) as the major fatty acids. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine; one unidentified polar lipid, one unidentified aminolipid and one unidentified lipid were also detected. This is the first time that a member of the genus Roseovarius has been isolated from the Arctic, which may promote the study of the distribution characteristics and environmental adaptability of this genus. On the basis of the data provided here, strain MK6-18T should be classed as representing a novel species of the genus Roseovarius , for which the name Roseovarius arcticus sp. nov. is proposed. The type strain is MK6-18T (=CCTCC AB 2018219T=KCTC 72187T).

Freshwater Pond

A novel bacterial strain, designated KMB7T, isolated from a freshwater pond in Taiwan, was characterized using a polyphasic taxonomic approach. Cells were Gram-stain-negative, motile by means of a single polar flagellum, rod-shaped and formed cream colonies. Optimal growth occurred at 25 °C, pH 7, and in the absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set (92 protein clusters) indicated that strain KMB7T is affiliated with species in the genus Aquabacterium . The 16S rRNA gene sequence similarity indicated that strain KMB7T is closely related to species within the genus Aquabacterium (95.2–97.6 % sequence similarity) and is most similar to A. fontiphilum CS-6T (97.6 %), followed by A. parvum B6T (97.5 %). The average nucleotide identity and digital DNA–DNA hybridization identity between strain KMB7T and the closely related strains were 74.6–78.0 % and 19.0–21.2 %, respectively. The major fatty acids of strain KMB7T were summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c), C18 : 1  ω7c and C16 : 0. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, diphosphatidylglycerol and four unidentified phospholipids. The sole isoprenoid quinone was ubiquinone-8 (Q-8). Genomic DNA G+C content of strain KMB7T was 65.4 %. On the basis of phenotypic and genotypic properties and phylogenetic inference, strain KMB7T should be classified in a novel species of the genus Aquabacterium , for which the name Aquabacterium lacunae sp. nov. is proposed. The type strain is KMB7T (=BCRC 81156T=LMG 30924T=KCTC 62867T).
