Comparative Genomic Analysis of Three Pseudomonas
microorganisms Article Comparative Genomic Analysis of Three Pseudomonas Species Isolated from the Eastern Oyster (Crassostrea virginica) Tissues, Mantle Fluid, and the Overlying Estuarine Water Column Ashish Pathak 1, Paul Stothard 2 and Ashvini Chauhan 1,* 1 Environmental Biotechnology Laboratory, School of the Environment, 1515 S. Martin Luther King Jr. Blvd., Suite 305B, FSH Science Research Center, Florida A&M University, Tallahassee, FL 32307, USA; [email protected] 2 Department of Agricultural, Food and Nutritional Science, University of Alberta, Edmonton, AB T6G2P5, Canada; [email protected] * Correspondence: [email protected]; Tel.: +1-850-412-5119; Fax: +1-850-561-2248 Abstract: The eastern oysters serve as important keystone species in the United States, especially in the Gulf of Mexico estuarine waters, and at the same time, provide unparalleled economic, ecological, environmental, and cultural services. One ecosystem service that has garnered recent attention is the ability of oysters to sequester impurities and nutrients, such as nitrogen (N), from the estuarine water that feeds them, via their exceptional filtration mechanism coupled with microbially-mediated denitrification processes. It is the oyster-associated microbiomes that essentially provide these myriads of ecological functions, yet not much is known on these microbiota at the genomic scale, especially from warm temperate and tropical water habitats. Among the suite of bacterial genera that appear to interplay with the oyster host species, pseudomonads deserve further assessment because Citation: Pathak, A.; Stothard, P.; of their immense metabolic and ecological potential. To obtain a comprehensive understanding on Chauhan, A. Comparative Genomic this aspect, we previously reported on the isolation and preliminary genomic characterization of Analysis of Three Pseudomonas Species three Pseudomonas species isolated from minced oyster tissue (P. -

1 Diversity and distribution of Nitrogen Fixation Genes in the Oxygen Minimum Zones of the 2 World Oceans 3 1Amal Jayakumar and 1Bess B. Ward 4 5 1Department of Geosciences 6 Princeton University 7 Princeton, NJ 08544 8 9 Abstract 10 Diversity and community composition of nitrogen fixing microbes in the three main oxygen 11 minimum zones (OMZs) of the world ocean were investigated using operational taxonomic unit 12 (OTU) analysis of nifH clone libraries. Representatives of the all four main clusters of nifH genes 13 were detected. Cluster I sequences were most diverse in the surface waters and the most abundant 14 OTUs were affiliated with Alpha- and Gammaproteobacteria. Cluster II, III, IV assemblages were 15 most diverse at oxygen depleted depths and none of the sequences were closely related to sequences 16 from cultivated organisms. The OTUs were biogeographically distinct for the most part – there was 17 little overlap among regions, between depths or between cDNA and DNA. Only a few 18 cyanobacterial sequences were detected. The prevalence and diversity of microbes that harbour nifH 19 genes in the OMZ regions, where low rates of N fixation are reported, remains an enigma. 20 21 Introduction 22 Nitrogen fixation is the biological process that introduces new biologically available 23 nitrogen into the ocean, and thus constrains the overall productivity of large regions of the ocean 24 where N is limiting to primary production. The most abundant and most important diazotrophs 25 in the ocean are cyanobacteria, members of the filamentous genus Trichodesmium and several 1 26 unicellular genera, including Chrocosphaera sp. -

There is limited information on the microbiology of thermal baths in their complexity, tracking community shifts from the thermal wells to the pools. In the present study, the natural microbial community of well and pool waters in Gellért bath was studied in detail by cultivation-based techniques. To isolate bacteria, 10% R2A and minimal synthetic media (with “bath water”) with agar–agar and gellan gum were used after prolonged incubation time; moreover, polyurethane blocks covered with media were also applied. Strains were identified by sequencing their 16S rRNA gene after grouping them by amplified rDNA restriction analysis. From each sample, the dominance of Alphaproteobacteria was characteristic though their diversity differed among samples. Members of Actinobacteria, Firmicutes, Beta- and Gamma- proteobacteria, Deinococcus–Thermus, and Bacteroidetes were also identified. Repre- sentatives of Deinococcus–Thermus phylum appeared only in the pool water. The largest groups in the pool water belonged to the Tistrella and Chelatococcus genera. The most dominant member in the well water was a new taxon, its similarity to Hartmannibacter diazotrophicus as closest relative was 93.93%. Keywords: cultivation, Gellért bath, well and pool waters, 16S rDNA, bacterial community structure Introduction Hot springs and thermal baths support diverse unique microbial communi- ties. -

Methods: Within a two-year interval, positive blood culture materials were assessed with Gram and FISH staining. Previously described and new FISH probes were combined to panels for Gram-positive cocci in grape-like clusters and in chains, as well as for Gram-negative rod-shaped bacteria. Covered pathogens comprised Staphylococcus spp., such as S. aureus, Micrococcus spp., Enterococcus spp., including E. faecium, E. faecalis, and E. gallinarum, Streptococcus spp., like S. pyogenes, S. agalactiae, and S. pneumoniae, Enterobacteriaceae, such as Escherichia coli, Klebsiella pneumoniae and Salmonella spp., Pseudomonas aeruginosa, Stenotrophomonas maltophilia, and Bacteroides spp. Results: A total of 955 blood culture materials were assessed with FISH. In 21 (2.2%) instances, FISH reaction led to non-interpretable results. With few exemptions, the tested FISH probes showed acceptable test characteristics even in the routine setting, with a sensitivity ranging from 28.6% (Bacteroides spp.) to 100% (6 probes) and a spec- ificity of >95% in all instances. -

However, there are many Pseudomonas species which are too divergent to the rest of the genus. This may interfere in the correct development of biological and ecological studies in which Pseudomonas are involved. Thus, we aimed to study the correct taxonomic placement of Pseudomonas species. Based on the study of their genomes and some evolutionary-based methodologies, we suggest the description of three new genera (Denitrificimonas, Parapseudomonas and Neopseudomonas) and many reclassifications of species Citation: Saati-Santamaría, Z.; previously included in Pseudomonas.

Pseudomonas aeruginosa y Acinetobacter baumanii, por ejemplo, constituyen patógenos oportunistas responsables de numerosas infecciones nosocomiales. La familia Pseudomonadaceae incluye además a la bacteria fitopatógena Pseudomonas syringae y a la fijadora de nitrógeno Azotobacter vinelandii, ambas con impacto en la agricultura. A pesar de que Pseudomonadaceae y Moraxellaceae han sido ampliamente estudiadas, pocos estudios han estado dirigidos a la determinación de marcadores moleculares que distingan a sus miembros de otros grupos de bacterias. Los marcadores indeles (inserciones/deleciones) en secuencias de proteínas conservadas han sido utilizados para estudios taxonómicos y evolutivos en bacterias. En el presente estudio se analiza si las inserciones identificadas en proteínas altamente conservadas constituyen marcadores moleculares para estudios taxonómicos y filogenéticos en Pseudomonadaceae y Moraxellaceae. Se analizaron secuencias de proteínas relacionadas con la replicación y la reparación del ADN, obtenidas de bases de datos internacionales y alineadas con el programa ClustalX2. -
