RESUMO
Aniline blue-decolourizing bacterial strain 502str22T, isolated from sediment collected in the East Pacific, was subjected to characterization by a polyphasic taxonomic approach. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain 502str22T belongs to the genus Novosphingobium, with closely related type strains 'Novosphingobium profundi' F72T (97.6%), N. mathurense SM117T (97.1%) and N. arvoryzae Jyi-02T (97.0%). Digital DNA-DNA hybridization and average nucleotide identity values between strain 502str22T and closely related type strains were 20.3-24.8% and 74.1-81.9%, respectively. The major cellular fatty acid (>10%) was C18:1 ω7c. The polar lipid profile consisted of a mixture of phosphatidylcholine, one sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylmonomethylethanolamine. The DNA G+C content of strain 502str22T was 65.5 mol%. The polyphasic taxonomic results indicated that strain 502str22T represents a novel species of the genus Novosphingobium, for which the name Novosphingobium decolorationis sp. nov is proposed. The type strain is 502str22T (=KCTC 82134T= MCCC 1K04799 T).

A Gram-staining-negative bacterium, designated 345S023T, was isolated from a sea water sample from the Indian Ocean. The results of 16S rRNA gene sequence analysis revealed that 345S023T represents a member of the genus Alteromonas, with closely related type strains Alteromonas fortis 1T (98.7â%), Alteromonas hispanica F-32T (98.6â%) and Alteromonas genovensis LMG 24078T (98.6â%). Up-to-date bacterial core gene set analysis revealed that 345S023T formed a phyletic lineage with Alteromonas australica H 17T. The case for 345S023T representing a novel species was supported by genomic results. Pairwise in silico DNA-DNA hybridization and average nucleotide identity values were much lower than the proposed and generally accepted species boundaries. Strain 345S023T contains ubiquinone-8 (Q-8) as the sole isoprenoid quinone, summed featured 3 (C16â:â1ω7c and/or C16â:â1ω6c), C16â:â0 and C18â:â1ω7c as the dominant cellular fatty acids (>10â%), and phosphatidylglycerol and phosphatidylethanolamine as the major polar lipids. The genome of strain 345S023T consisted of a 4.4 Mb chromosome with a DNA G+C content of 44.4â%. On the basis of these genomic, chemotaxonomic and phenotypic characteristics, we propose a novel species: Alteromonas profundi sp. nov. The type strain is 345S023T(=JCM 33893T=MCCC 1K04570T).

A Gram-stain-negative bacterium, designated strain 40Bstr34T, isolated from a sediment sample from the West Pacific Ocean, was taxonomically characterized by using a polyphasic approach. The strain was phylogenetically close to Jiella aquimaris LZB041T and Jiella endophytica CBS5Q-3T, with 16S rRNA gene sequence similarities of 98.5 and 97.1â%, respectively. The genome of strain 40Bstr34T featured a G+C content of 65.7 % for a 5.8 Mb chromosome. Up-to-date bacterial core gene set analysis revealed that strain 40Bstr34T represents one independent lineage with J.aquimaris LZB041T. In silico DNA-DNA hybridization values between strain 40Bstr34T and its phylogenetic neighbours ranged from 30.3-34.2 %, below the cutoff of 70â%. In addition, the corresponding average nucleotide identity values were between 81.8-83.7â%, which are lower than 95â% threshold. The predominant cellular fatty acids of strain 40Bstr34T were summed feature 8 (C18â:â1 ω6c and/or C18â:â1 ω7c), cyclo-C19â:â0 ω8c and iso-C17â:â0 3-OH, and ubiquinone-10 as the predominant respiratory quinone. The major polar lipids included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, two unidentified aminolipids and two unidentified lipids. Based on the results of phenotypic, chemotaxonomic and genetic analyses, strain 40Bstr34T is identified as representing a novel species of the genus Jiella for which the name Jiella pacifica sp. nov. is proposed. The type strain is 40Bstr34T (=JCM 33903T=MCCC 1K04569T).

Up-to-date bacterial core gene set analysis revealed that strain 501str8T represented one independent lineage with M. aquimarina SW-63T. The average nucleotide identity values of strain 501str8T with M. aquimarina SW-63T and M. lutimaris SMK-108T were 80.2 and 81.3â%, respectively. In silico DNA-DNA hybridization values between strain 501str8T and M. aquimarina SW-63T and M. lutimaris SMK-108T were 22.8 and 32.9â%, respectively. The predominant isoprenoid quinone was menaquinone-6, and iso-C15â:â0, iso-C17â:â0 3-OH and iso-C15â:â1 G were the dominant cellular fatty acids. The G+C content of the genomic DNA was 42.8 mol%. Differential phylogenetic distinctiveness and chemotaxonomic differences, together with the phenotypic properties observed in this study, revealed that strain 501str8T could be differentiated from closely related species. Therefore, we propose that strain 501str8T represents a novel species of the genus Muricauda, for which the name Muricauda oceani sp. nov. is suggested. The type strain is 501str8T (=JCM 33902T=MCCC 1K04567T).

RESUMO
A Gram-stain-negative bacterium, designated strain IO390401T, was isolated from a seawater sample from the sulphide region of the Indian Ocean.

A novel, alkaliphilic, psychrotolerant, facultative anaerobe, designated CP1T, was isolated from sandy soil near the Davis Station in Antarctica. The short-rod-shaped cells displayed Gram-positive staining and did not form spores. Strain CP1T was able to grow at temperatures between 4 and 36 °C, pH 6.0-9.5, and in the presence of up to 5.0â% (w/v) NaCl. 16S rRNA gene and multilocus (pheS, rpoA, and atpA) sequence analysis revealed Carnobacterium mobile DSM 4848T and Carnobacterium iners LMG 26642T as the closest relatives (97.4 and 97.1â% 16S rRNA gene sequence similarity, respectively). The genomic G+C content was 38.1 mol%, and DNA-DNA hybridization with DSM 4848T revealed 32.4±3.4â% similarity. The major fatty acid components were C14â:â0 and C16â:â1ω9c. The cell wall contained meso-diaminopimelic acid and was of peptidoglycan type A1γ. Based on physiological, genotypic and biochemical characteristics, strain CP1T represents a novel species of the genus Carnobacterium for which the name Carnobacterium antarcticum sp. nov. is proposed. The type strain is CP1T (=DSM 103363T=CGMCC 1.15643T).

We have previously shown that non-structural protein p35, encoded by Scylla serrata reovirus (SsRV) S10, may act as a viroporin. To characterize the role of p35 protein in the modulation of cellular function, a yeast two-hybrid system was used to screen a cDNA library derived from S. serrata to find its interacting partner. Protein interactions were confirmed in vitro by GST pull-down. Full cDNAs of p35 interactors were cloned by the rapid amplification of cDNA ends. After two-hybrid library screening, we isolated partial cDNAs encoding hemocyanin, cryptocyanin, and TAX1BP1. Interaction of p35 with each of hemocyanin, cryptocyanin, and TAX1BP1 was confirmed by GST pull-down. The full-length cDNA fragments of hemocyanin, cryptocyanin, and TAX1BP1 were 2287, 2422, and 3437 bp, respectively, and they encoded three putative proteins with molecular masses of ~76.9, ~79.2, and ~107.2 kDa, respectively. This study casts new light on the function and physiological significance of p35 during the SsRV replication cycle.

RESUMO
Objective: The objective of this study was to assess bacterial diversity in sediment samples from two stations (WBC1305 and WBC1316A) in the Pacific polymetallic nodule province. Methods: The environmental total DNAs were extracted, and 6 bacterial 16S rRNA gene libraries were generated from 6 sediment layers. The Shannon diversity index and Simpson dominance index were calculated for each bacterial community and then compared. The bacterial community structure of each sediment sample was analyzed, and the results were used to construct phylogenetic trees. Results: In total, 533 bacterial clones were obtained from 6 bacterial clone libraries. Among these 533 clones, 472 clones could be assigned to 16 phylogenetic groups (Acidobacteria, Actinobacteria, Alpha, Beta, Delta, gamma-Proteobacteria, Bacteroidetes, Chloroflexi, Firmicutes, Gemmatimonadetes, Nitrospirae, Planctomycetes, Elusimicrobia, Hydrogenedentes, Chlorobi, and Nitrospinae), whereas the remaining 61 clones could not be classified into any known groups. Conclusion: The bacterial communities in sediments from WBC1305 are dominated mainly by gamma-Proteobacteria and from WBC1316A by Firmicutes. In addition, the bacterial community structure at WBC1316A is more abundant and complex than that at WBC1305.

RESUMO
We describe the isolation and identification of a gene encoding 4-hydroxyphenylpyruvate dioxygenase (HPPD (EC 1.13.11.27)) from the red-brown pigment-producing bacterium Alteromonas stellipolaris LMG 21856. HPPD directs the synthesis of 2,5-dihydroxyphenylacetic acid (homogentisic acid (HGA)). The sequence of the deduced peptide showed homology to HPPDs from other strains of Alteromonas; the greatest similarity was to the hypothetical HPPD from Alteromonas sp. SN2. As observed for HPPDs from other sources, expression of the A. stellipolaris HPPD gene in Escherichia coli cells could be detected by the gradual development of a brown pigment in cultures as a result of the spontaneous oxidation and polymerization of HGA.
