Abstract
A Gram-stain-negative bacterial strain, designated as E165T, was isolated from a tidal flat sediment of the East China Sea. Strain E165T grew optimally at pH 6, at 32 °C and with 1–2 % (w/v) NaCl. The 16S rRNA gene sequence similarity results revealed that strain E165T was most closely related to
Marinomonas rhizomae
IVIA-Po-145T,
Marinomonas polaris
CK13T,
Marinomonas foliarum
IVIA-Po-155T,
Marinomonas hwangdonensis
HDW-15T,
Marinomonas pontica
46-16T,
Marinomonas mangrovi
B20-1T and
Marinomonas shanghaiensis
DSL-35T with values of 97.0–98.5 %. The digital DNA–DNA hybridization and average nucleotide identity values between strain E165T and the reference strains were 21.9–34.3 % and 77.6–87.3 %, respectively. The DNA G+C content of the isolate was 42.9 mol%. Strain E165T contained Q-8 as the sole ubiquinone and C16 : 0, summed feature 8 (C18 : 1
ω7c and/or C18 : 1
ω6c) and summed feature 3 (C16 : 1
ω7c and/or C16 : 1
ω6c) as the major fatty acids. The major polar lipids of strain E165T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, aminolipid and aminophospholipid. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness, a novel species, Marinomonas lutimaris sp. nov., is proposed with E165T (=MCCC 1K06241T=KCTC 82809T) as the type strain.

Abstract
A Gram-stain-negative, non-motile, facultatively anaerobic, short rod-shaped bacterium, designated HB171799T, was isolated from seacoast sandy soil collected at Qishui Bay, Hainan, PR China. The chemotaxonomic analysis revealed that the respiratory quinones were Q-8 and Q-7, and the major cellular fatty acids were summed feature 8 (comprising C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0 and C18 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified phospholipid and an unidentified lipid. The size of the draft genome was 3.68 Mb with a DNA G+C content of 48.0 mol%. Results of phylogenetic analyses based on 16S rRNA gene and genome sequences showed that the novel isolate belonged to the family Oceanospirillaceae and formed a distinct subcluster at the base of the radiation of the genus Marinomonas. The highest sequence similarity (96.0 %) of the novel isolate was found to the type strains of Marinomonas fungiae JCM 18476T and Marinomonas ostreistagni DSM23425T. The whole genome-based phylogeny and differences in cellular fatty acids and polar lipids readily distinguished strain HB171799T from all the closely related validly published type strains. Strain HB171799T is therefore suggested to represent a novel species of a new genus in the family Oceanospirillaceae, for which the name Maribrevibacterium harenarium gen. nov., sp. nov. is proposed. The type strain is HB171799T (=CGMCC 1.16727T=JCM 33332T).

Abstract
A Marinomonas-like, Gram-stain-negative, strictly aerobic and rod to ovoid-shaped bacterium, designated as strain A79T, was isolated from the seawater mixtures of oyster shells and brown algae in a coastal intertidal zone of Zhoushan, China. The strain was positive for oxidase and catalase. Colonies grown on marine agar for 48 h were round, milky white, smooth and moist with the diameter of 2-3 mm. Growth was observed at 15-30 °C (optimum, 25℃), pH 5.5-9.5 (optimum, pH 8.5) and with 0.5-8% (w/v) NaCl (optimum, 2-2.5%). The G + C content based on the genome sequence was 46.0%. The only respiratory quinone was Q-8. The main polar lipids contained phosphatidylglycerol, phosphatidylethanolamine, unidentified glycolipids, unidentified phospholipid and three unidentified lipids. The major fatty acids (> 10%) were C16:0, Summed feature 3 (comprising C16:1 ω6c and/or C16:1 ω7c) and summed feature 8 (comprising C18:1 ω6c and/or C18:1 ω7c). The 16S rRNA gene sequence similarity between strain A79T and Marinomonas pollencensis IVIA-Po-185T was 97.4%, the similarities with other type strains of the genus Marinomonas were 93.8-96.7%. Based on the results, Marinomonas vulgaris sp. nov. was proposed as a novel species. The type strain is A79T (= MCCC 1K05799T = KCTC 82519T = JCM 34473T).

Abstract
Two Gram-stain-negative, aerobic, rod-shaped bacteria, polar flagellated, designated strains SM2066T and SM1966T, were respectively isolated from the surfaces of Colpomenia sinuosa and Ulva pertusa macroalgae collected off the coastal areas of Rongcheng, PR China. Strain SM2066T grew at 8-37 °C and with 0.5-7.0 % (w/v) NaCl, while strain SM1966T grew at 5-30 °C and with 0.5-8.5% (w/v) NaCl. Both of them reduced nitrate to nitrite and required Na+ for growth but neither of them hydrolysed starch and DNA. Phylogenetic analysis based on 16S rRNA gene and single-copy orthologous cluster sequences revealed that both strains SM2066T and SM1966T were affiliated with the genus Marinomonas but formed distinct phylogenetic branches from known Marinomonas species, respectively sharing the highest 16S rRNA gene sequence similarities with type strains of Marinomonas ushuaiensis (97.9 %) and Marinomonas blandensis (96.7 %). The digital DNA-DNA hybridization and average nucleotide identity values between strains SM2066T and SM1966T and type strains of closely related Marinomonas species were all below 22.9 and 79.9 mol%, respectively. The major fatty acids of the two strains were summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c), summed feature 8 (C18 : 1 ω7c) and C16 : 0, with their predominant polar lipids being phosphatidylethanolamine and phosphatidylglycerol, and their sole respiratory quinone being Q-8. The genomic DNA G+C contents of strains SM2066T and SM1966T determined from genomic sequences were 40.3 and 41.6 mol%, respectively. On the basis of the polyphasic evidence presented in this study, strains SM2066T and SM1966T are considered to represent two novel species within the genus Marinomonas, for which the names Marinomonas colpomeniae sp. nov. and Marinomonas algicola sp. nov. are proposed. The type strains are SM2066T (=MCCC 1K04390T= KCTC 82372T) and SM1966T (=MCCC 1K04387T= KCTC 72848T), respectively.

Abstract
A Gram-stain-negative, aerobic, polarly flagellated, straight or curved rod-shaped bacterium, designated strain M1K-6T, was isolated from deep seawater samples collected from the Mariana Trench. The strain grew at -4 to 37 °C (optimum, 25-30 °C), at pH 5.5-10.0 (optimum, pH 7.0) and with 0.5-14.0 % (w/v) NaCl (optimum, 2.0 %). It did not reduce nitrate to nitrite nor hydrolyse gelatin or starch. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M1K-6T was affiliated with the genus Marinomonas, sharing 93.1-97.0 % sequence similarity with the type strains of recognized Marinomonas species. The major cellular fatty acids were summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c), summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c), C16 : 0, C10 : 0 3-OH and C18 : 0. The predominant respiratory quinone was ubiquinone-8. Polar lipids of strain M1K-6T included phosphatidylethanolamine, phosphatidylglycerol and two unidentified lipids. The genomic G+C content of strain M1K-6T was 46.0 mol%. Based on data from the present polyphasic study, strain M1K-6T was considered to represent a novel species within the genus Marinomonas, for which the name Marinomonas profundi sp. nov. is proposed. The type strain is M1K-6T (=KCTC 72501T=MCCC 1K03890T).

Abstract
For deep-sea hydrothermal vent crabs, recent investigations have revealed some epibiotic bacteria, but no study has described the bacterial community associated with the gill and intestine. In this study, the microbiota attached to the gill and intestine of the hydrothermal vent crab Austinograea sp. and two shallow-water crab species (Eriocheir sinensis and Portunus trituberculatus) were compared by high-throughput sequencing of 16S rDNA genes. The highest and lowest diversity in bacterial communities were observed in the gill and intestine of Austinograea sp., respectively. Non-metric multidimensional scaling (NMDS) analysis indicated that Austinograea sp. harbored a distinct microbial community. Operational taxonomic units (OTUs) for phylum Fusobacteria, class Epsilonproteobacteria, and genera Leucothrix, Polaribacter, Fusibacter, etc. were dominant in Austinograea sp. Of these, Leucothrix, Sulfurospirillum, and Arcobacter may be involved in oxidizing reduced sulfur compounds and sulfur metabolism; Marinomonas, Polaribacter adapted to the low temperature, and Fusibacter and Psychrilyobacter may survive well under hypoxic conditions. Bacteria commonly present in seawater were dominant in the gill, whereas anaerobic bacteria showed strikingly high abundance in the intestine. Interestingly, Firmicutes and Epsilonproteobacteria may complement each other in Austinograea sp., forming an internal environment. The diversified microbial community of Austinograea sp. reveals adaptation to the hydrothermal vent environment.

Abstract
A novel Gram-staining-negative, chemoorganotrophic, moderately halophilic, strictly aerobic bacterium, strain MED121T, was isolated from a seawater sample collected at the Blanes Bay Microbial Observatory in the north-western Mediterranean Sea. Analysis of its 16S rRNA gene sequence, retrieved from the whole-genome sequence, showed that this bacterium was most closely related to Marinomonas dokdonensis and other Marinomonas species (96.3 and 93.3-95.7 % sequence similarities, respectively), within the family Oceanospirillaceae. Strain MED121T was included into a whole-genome sequencing study and, subsequently, it was characterized using a polyphasic taxonomic approach. It was found to be oxidase and catalase positive, its cells are cocci to short rods, it does not ferment carbohydrates and does not reduce nitrate to nitrite or gas and it requires at least 2.5 % (w/v) marine salts and tolerates up to 7 % (w/v) salts. Its major cellular fatty acids in order of abundance are C16 : 1ω7c/C16 : 1ω6c, C18 : 1ω7c, C16 : 0 and C10 : 0 3-OH. Its genome had an approximate length of 5.1 million bases and a DNA G+C content equal to 40.9 mol%. Analysis of the annotated genes reveals the capacity for the synthesis of ubiquinone 8 (Q8) and the polar lipids phosphatidylglycerol and phosphatidylethanolamine, in agreement with other members of the genus. All the data collected supported the creation of a novel species to accommodate this bacterium, for which the name Marinomonas blandensis sp. nov. is proposed. The type strain is MED121T (=CECT 7076T=LMG 29722T).

Abstract
Recalcitrant polycyclic aromatic hydrocarbons (PAHs) released into seawater end up in the deep sea sediments (DSSs). However, their fate here is often oversimplified by theoretical models. Biodegradation of PAHs in DSSs, is assumed to be similar to biodegradation in surface habitats, despite high hydrostatic pressures and low temperatures that should significantly limit PAH biodegradation. Bacteria residing in the DSSs (related mainly to α- and γ-Proteobacteria) have been shown to or predicted to possess distinct genes, enzymes and metabolic pathways, indicating an adaptation of these bacterial communities to the psychro-peizophilic conditions of the DSSs. This work summarizes some of the most recent research on DSS hydrocarbonoclastic populations and mechanisms of PAH degradation and discusses the challenges posed by future high CO2 and UV climate scenarios on biodegradation of PAHs in DSSs.

Abstract
A novel Gram-stain-negative, facultatively anaerobic, rod-shaped, agar-digesting bacterial strain, designated HQM9T, was isolated from the surface of the marine red alga Gelidium amansii collected from the intertidal zone of Weihai, China. Cells of HQM9T were 3.0–4.0 μm long and 0.2–0.3 μm wide and lacked flagella. The new isolate grew optimally at 28–30 °C, at pH 7.0–7.5, and in the presence of 2.5–3.0 % NaCl. The predominant cellular fatty acids were iso-C15 : 0 and iso-C17 : 0 3-OH. The sole menaquinone was MK-6. The DNA G+C content was 33 mol%. The major polar lipids were comprised of phosphatidylethanolamine and four unknown polar lipids. Based on the 16S rRNA gene sequence, the closest relative was Aquimarina agarilytica ZC1T with 97.16 % sequence similarity, with which strain HQM9T formed a distinct cluster belonging to the genus Aquimarina in a phylogenetic tree. Moreover, average nucleotide identity and estimated DNA–DNA hybridization values between strains HQM9T and ZC1T were 78.7 % and 12.50 ± 2.95 %, respectively. On the basis of phenotypic, chemotaxonomic and phylogenetic analysis, strain HQM9T represents the type strain of a novel species within the genus Aquimarina in the family Flavobacteriaceae, phylum Bacteroidetes, for which the name Aquimarina agarivorans sp. nov. is proposed. The type strain is HQM9T ( = ATCC BAA-2612T = CICC 10835T).

List of new names and new combinations previously effectively, but not validly, published. Int J Syst Evol Microbiol 2015. [DOI: 10.1099/ijs.0.000008-0] [Citation(s) in RCA: 64] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022] Open
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.
