Abstract
Three psychrophilic bacteria, designated as strains SQ149T, SQ345T, and S1-1T, were isolated from deep-sea sediment from the South China Sea. All three strains were the most closely related to Thalassotalea atypica RZG4-3-1T based on the 16S rRNA gene sequence analysis (similarity ranged from 96.45 to 96.67 %). Phylogenetic analysis based on the 16S rRNA gene and core-genome sequences showed that three strains formed a cluster within the genus Thalassotalea. The average amino acid identity, average nucleotide identity, and digital DNA-DNA hybridization values among the three strains and closest Thalassotalea species were far below the cut-off value recommended for delineating species, indicating they each represented a novel species. All three strains were Gram-stain-negative, rod-shaped, and contained summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c) as the predominant fatty acid, Q-8 as the major respiratory quinone, and phosphatidylethanolamine and phosphatidylglycerol as predominant polar lipids. Based on the genomic, phylogenetic, and phenotypic characterizations, each strain is considered to represent a novel species within the genus Thalassotalea, for which the names Thalassotalea psychrophila sp. nov. (type strain SQ149T=MCCC 1K04231T=JCM 33807T), Thalassotalea nanhaiensis sp. nov. (type strain SQ345T=MCCC 1K04232T=JCM 33808T), and Thalassotalea fonticola sp. nov. (type strain S1-1T=MCCC 1K06879T=JCM 34824T) are proposed.

Abstract
The genus Thalassotalea is ubiquitous in marine environments, and up to 20 species have been described so far. A Gram-staining-negative, aerobic bacterium, designated strain PTE2T was isolated from laboratory-reared larvae of the Japanese sea cucumber Apostichopus japonicus. Phylogenetic analysis based on the 16S rRNA gene nucleotide sequences revealed that PTE2T was closely related to Thalassotalea sediminis N211T (= KCTC 42588T = MCCC 1H00116T) with 97.9% sequence similarity. ANI and in silico DDH values against Thalassotalea species were 68.5-77.0% and 19.7-24.6%, respectively, indicating the novelty of PTE2T. Based on genome-based taxonomic approaches, strain PTE2T (= JCM 34608T = KCTC 82592T) is proposed as a new species, Thalassotalea hakodatensis sp. nov.

Abstract
A novel Gram-stain-negative, strictly aerobic bacterium that has a rod-like shape with a single polar flagellum in the exponential phase of growth and a spherical or ovoid shape without a flagellum in the stationary phase was isolated from a mangrove wetland sediment sample collected at Beilun Estuary National Nature Reserve, Guangxi Province, PR China and designated strain ZS-4T. This strain grew optimally at pH 6.0-8.0, at a temperature of 37 °C and in the presence of 3-4 % (w/v) NaCl. Its polar lipid profile included phosphatidylethanolamine, phosphatidylglycerol, one unidentified aminophospholipid and two uncharacterized lipids. Ubiquinone 8 (Q-8) was the sole respiratory quinone and the cellular fatty acids were dominated by C17 : 1ω8c and C16 : 0. A phylogenetic analysis based on the 16S rRNA gene sequence showed that strain ZS-4T exhibited its highest similarities to the type strains Thalassotalea litorea HMF4135T (97.8 %) and Thalassotalea ponticola GJSW-36T (95.9 %). A whole genome-level comparison of strain ZS-4T with T. litorea MCCC 1K03283T revealed an average nucleotide identity value of 75.6 % and a calculated DNA-DNA hybridization value of 19.6 %. In addition, the genomic DNA G+C content of strain ZS-4T was 45.9 mol%. Thus, based on analyses of its morphology, physiology, fatty acid composition and 16S rRNA gene sequence, strain ZS-4T should be considered a novel species of the genus Thalassotalea, with the proposed name Thalassotaleamangrovi sp. nov. The type strain is ZS-4T (=KCTC 72399T=MCCC 1K03630T).

Abstract
A Gram-stain-negative, aerobic, motile and rod-shaped or ovoid bacterial strain, designated JDTF-40T, was isolated from a tidal flat in Jindo, an island of the Republic of South Korea. Strain JDTF-40T grew optimally at pH 7.0-8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain JDTF-40T fell within the cluster comprising the type strains of Thalassotalea species. Strain JDTF-40T exhibited 16S rRNA gene sequence similarity values of 93.8-95.7 % to the type strains of Thalassotalea species. Strain JDTF-40T contained Q-8 as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major fatty acids. The major polar lipids of strain JDTF-40T were phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid, one unidentified glycolipid and three unidentified lipids. The DNA G+C content of strain JDTF-40T was 41.3 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain JDTF-40T is distinct from recognized species of the genus Thalassotalea. On the basis of the data presented here, strain JDTF-40T is considered to represent a novel species of the genus Thalassotalea, for which the name Thalassotalea insulae sp. nov. is proposed. The type strain is JDTF-40T (=KACC 19433T=KCTC 62186T=NBRC 113040T).

Abstract
A novel Gram-stain-negative, straight or slightly curved rod-shaped, non-spore-forming, non-flagellated, strictly aerobic strain, designated RZG4-3-1T, was isolated from coastal seawater of Rizhao, China (119.625° E 35.517° N). The organism grew optimally at 24-28 °C, at pH 7.0 and in the presence of 2.0 % (w/v) NaCl. The strain required seawater or artificial seawater for growth, and NaCl alone did not support growth. Strain RZG4-3-1T contained ubiquinone 8 (Q-8) as the major respiratory quinone and contained C16 : 1ω7c and/or C16 : 1ω6c and C16 : 0 as the dominant fatty acids. The polar lipids of strain RZG4-3-1T were phosphatidylethanolamine, phosphatidylglycerol and one unidentified aminophospholipid. The DNA G+C content of strain RZG4-3-1T was 40.1 mol%. Strain RZG4-3-1T exhibited the highest 16S rRNA gene sequence similarity value (96.0 %) to Thalassotalea eurytherma JCM 18482T. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RZG4-3-1T belonged to the genus Thalassotalea. On the basis of polyphasic analyses, strain RZG4-3-1T represents a novel species of the genus Thalassotalea, for which the name Thalassotalea atypica sp. nov. is proposed. The type strain is RZG4-3-1T (=JCM 31894T=KCTC 52745T=MCCC 1K03276T). An emended description of Thalassotalea eurytherma is also provided.

Abstract
Strain Eup a-8T, isolated from a torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup a-8T were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, poly-β-hydroxybutyrate-containing, rod-shaped and formed white colonies. Optimal growth occurred at 25-30 °C, pH 7-8, and in the presence of 2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup a-8T belonged to the genus Thalassotalea and showed the highest levels of sequence similarity with respect to Thalassotalea ganghwensis JC2041T (97.1 %). Strain Eup a-8T contained C17 : 1ω8c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C14 : 0 and iso-C16 : 0 as the predominant fatty acids. The only isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and one uncharacterized phospholipid. Genomic DNA G+C content of strain Eup a-8T was 41.5 mol%. The DNA-DNA hybridization value for strain Eup a-8T with Thalassotalea ganghwensis JC2041T was less than 70 %. Differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain Eup a-8T should be classified as a novel species of the genus Thalassotalea, for which the name Thalassotalea coralli sp. nov. is proposed. The type strain is Eup a-8T (=BCRC 80967T=LMG 29478T=KCTC 52169T).

Abstract
The Gram-stain-negative, rod-shaped, strictly aerobic, motile bacterial strain, designated YM155T, was isolated from a seamount near the Yap Trench in the tropical western Pacific. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain YM155T was related to the genus Thalassotalea and had highest 16S rRNA gene sequence similarities with the type strains of Thalassotalea piscium T202T (97.2 %) and Thalassotalea agariperforans M-M1T (97.2 %). The predominant cellular fatty acids were C17 : 1ω8c, summed feature 3 (composed of iso-C15 : 0 2-OH and/or C16 : 1ω7c) and iso-C16 : 0. Ubiquinone 8 (Q-8) was the respiratory quinone. The polar lipid profile contained phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids and one unidentified lipid. The genomic DNA G+C content of strain YM155T was 36.1 mol%. On the basis of the evidence presented in this study, strain YM155T represents a novel species of the genus Thalassotalea, for which we propose the name Thalassotalea profundi sp. nov. (type strain YM155T=KACC 18563T=CGMCC 1.15922T).

Abstract
A novel Gram-stain-negative, aerobic and rod-shaped marine bacterium, designated strain HMF4135T, was isolated from a sand sample which was collected from the seashore of the South Sea, Republic of Korea. It required NaCl for growth and exhibited optimal growth at 30 °C, with 2 % (w/v) NaCl and at pH 7-8. Cellular fatty acids were dominated by C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 1ω9c and C12 : 0 3-OH. The predominant isoprenoid quinone was ubiquinone-8 (Q-8). Polar lipids consisted of phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content was 41.9 mol%. Phylogeny based on 16S rRNA gene sequences showed that strain HMF4135T formed a distinct species-level lineage within the genus Thalassotalea of the class Gammaproteobacteria and was most closely related to Thalassotalea ponticola GJSW-36T (96.4 % similarity). Based on the distinctive phenotypic characteristics and phylogenetic analysis, it is concluded that strain HMF4135T represents a novel species of the genus Thalassotalea, for which the name Thalassotalea litorea sp. nov. is proposed. The type strain is HMF4135T (=KCTC 52154T=NBRC 112672T).

Abstract
A Gram-staining-negative, aerobic, rod-shaped bacterial strain, designated LPB0090T, was isolated from the Pacific oyster, Crassostreagigas, collected from the Yeongheung Island, Korea (37° 15' 16.1″ N; 126° 29' 46.5″ E). The complete genome sequence of LPB0090T (accession number CP017689) was 3 861 670 bp long with a DNA G+C content of 38.8 mol%. The genome included 3245 protein-coding genes and six copies of rRNA operons. On the basis of the results of 16S rRNA gene sequence analysis, LPB0090T was found to form an independent phyletic line within the genus Thalassotalea, with 94.7-96.0 % sequence similarities to the previously known species of the genus. The isoprenoid quinone (Q-8) and major fatty acids (C16 : 0, C17 : 1 ω8c, and C16 : 1 ω7c and/or C16 : 1 ω6c) of the isolate were similar to those of the other members of the genus Thalassotalea. A number of phenotypic features, however, distinguished LPB0090T from its closest neighbour Thalassotalea ponticola as well as other species of the genus Thalassotalea. On the basis of the phylogenetic, genomic and phenotypic data presented in this study, the strain was classified as representing a novel species of the genus Thalassotalea. Therefore, the name Thalassotalea crassostreae sp. nov. is proposed for the isolate. The type strain is LPB0090T (=KACC 18695T=JCM 31189T).

Abstract
Strain Eup-16T, isolated from the torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup-16T were Gram-staining-negative, aerobic, motile by means of a single polar flagellum, contained poly-β-hydroxybutyrate, rod-shaped and formed pale yellow colonies. Optimal growth occurred at 25-30 °C, pH 7.5-9 and in the presence of 1 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup-16T belonged to the genus Thalassotalea and was most closely related to Thalassotalea montiporae CL-22T with sequence similarity of 98.4 %. Strain Eup-16T contained summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C18 : 1ω7c, C16 : 0 and C17 : 1ω8c as the predominant fatty acids. The predominant isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain Eup-16T was 43.2 mol%. The DNA-DNA hybridization value for strain Eup-16T with T. montiporae CL-22T was less than 34 %. Differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain Eup-16T should be classified as a representative of a novel species of the genus Thalassotalea, for which the name Thalassotalea euphylliae sp. nov. is presented. The type strain is Eup-16T (=BCRC 80910T=LMG 29001T=KCTC 42743T).

Abstract
A bacterial strain, designated CL-22T, was isolated from an encrusting pore coral, Montipora aequituberculata, collected off the coast of Southern Taiwan. Its taxonomic position was investigated using a polyphasic approach. Cells of strain CL-22T were Gram-stain-negative, aerobic, motile by means of a single polar flagellum, rod-shaped and formed yellow colonies. Optimal growth occurred at 30 °C, pH 6.5-7 and in 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree, based on 16S rRNA gene sequences, showed that strain CL-22T fell into the clade comprising the type strains of species of the genus Thalassotalea. Strain CL-22T exhibited 16S rRNA gene sequence similarity values of 94.7-97.1 % to the type strains of species of the genus Thalassotalea. The major fatty acids (>10 %) of strain CL-22T were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The predominant isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain CL-22T was 41.2 mol%. The differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain CL-22T should be classified as a novel species of the genus Thalassotalea; the name Thalassotalea montiporae sp. nov. is proposed. The type strain is CL-22T (=LMG 24827T=BCRC 17940T).

Abstract
A novel Gram-stain negative, facultatively anaerobic, rod-shaped and yellowish-white-pigmented marine bacterium, designated strain N211(T), was isolated from marine sediment obtained off the coastal area of Weihai, China. The cells are approximately 0.4-0.9 × 1.8-3.5 μm in size and motile by means of a polar flagellum. The strain grows optimally at 33 °C, pH 7.5-8.5 and in the presence of 3.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences indicated that strain N211(T) fell within the clade comprising the type strains of species of the genus Thalassotalea. Strain N211(T) was most closely related to Thalassotalea ganghwensis DSM 15355(T) (96.4 %) based on the 16S rRNA gene sequence, and shared 94.4-96.4 % similarity with type strains of all members of the genus Thalassotalea. The predominant isoprenoid quinone of strain N211(T) was identified as ubiquinone-8 (Q-8). The major polar lipids were found to be phosphatidylethanolamine, phosphatidylglycerol and an unidentified lipid. C17:1 w8c, summed feature 3 (C16:1 w7c and/or iso-C 15:0 2-OH) and C16:0 were found to be main cellular fatty acids. The G+C content of the genomic DNA is 39.1 mol%. It is evident from phenotypic data and phylogenetic inference that strain N211(T) represents a novel species of the genus Thalassotalea, for which the name T. sediminis sp. nov. is proposed. The type strain is N211(T) (=KCTC 42588(T) = MCCC 1H00116(T)).

Abstract
A Gram-stain-negative, facultatively anaerobic bacterium, strain QBLM2T, was isolated from rearing water of a marine recirculating aquaculture system in Tianjin, China. Its taxonomic position was investigated through a polyphasic approach. Cells of strain QBLM2T were non-spore-forming rods, motile by means of a single polar flagellum. Positive for oxidase and catalase. Growth occurred at 15-40 °C (optimum 30 °C), at pH 6.5-10.5 (optimum pH 7.5-8.5) and in the presence of 0-5.0 % (w/v) NaCl (optimum 3 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain QBLM2T formed a distinct lineage within the genus Thalassotalea and exhibited sequence similarities of 94.5-96.3 % to members of the genus Thalassotalea. The predominant fatty acids (>10 %) were C17 : 1ω8c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Ubiquinone 8 (Q-8) was the major ubiquinone. The DNA G+C content was 37.1 mol%. Based on the data above, strain QBLM2T is considered to represent a novel species of the genus Thalassotalea, for which the name Thalassotalea marina sp. nov. is proposed. The type strain is QBLM2T ( = CGMCC 1.12814T = KCTC 42731T). Phylogenetic analyses indicated that Thalassomonas eurytherma Za6a-12T fell within the genus Thalassotalea, so it is reclassified as Thalassotalea eurytherma comb. nov. and the description of the genus Thalassotalea is emended.

Abstract
A Gram-stain-negative, aerobic, non-flagellated and rod-shaped or ovoid bacterial strain, designated GJSW-36(T), was isolated from seawater at Geoje island in the South Sea, South Korea. Strain GJSW-36(T) grew optimally at pH 7.0-8.0, at 25 °C and in the presence of 2% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain GJSW-36(T) fell within the clade comprising the type strains of species of the genus Thalassotalea and Thalassomonas fusca. Strain GJSW-36(T) exhibited 16S rRNA gene sequence similarity values of 94.2-96.0% to the type strains of species of the genus Thalassotalea and Thalassomonas fusca and of 93.8-94.5% to the type strains of the other species of the genus Thalassomonas. Strain GJSW-36(T) contained ubiquinone-8 (Q-8) as the predominant ubiquinone and summed feature 3 (C(16:1)ω7c and/or C(16:1)ω6c), C(1:1)ω8c and C(16:0) as the major fatty acids. The major polar lipids of strain GJSW-36(T) were phosphatidylglycerol and phosphatidylethanolamine. The DNA G+C content of strain GJSW-36(T) was 45.1 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain GJSW-36(T) is separated from species of the genus Thalassotalea and Thalassomonas fusca. On the basis of the data presented, strain GJSW-36(T) is considered to represent a novel species of the genus Thalassotalea, for which the name Thalassotalea ponticola sp. nov. is proposed. The type strain is GJSW-36(T) ( =KCTC 42155(T) =CECT 8656(T)). From this study, it is also proposed that Thalassomonas fusca should be reclassified as a member of the genus Thalassotalea and the description of the genus Thalassotalea is emended.

Abstract
The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.
