Polaromonas naphthalenivorans strain CJ2 is a Gram-negative betaproteobacterium that was identified, using stable isotope probing in 2003, as a dominant in situ degrader of naphthalene in coal tar-contaminated sediments. The sequenced genome of strain CJ2 revealed several genes conferring nitrogen fixation within a 65.6 kb region of strain CJ2's chromosome that is absent in the genome of its closest sequenced relative Polaromonas sp. strain JS666. Laboratory growth and nitrogenase assays… Expand

This study provides the first molecular insight into the mobile DNA of Polaromonas spp. Expand
Nitrogen Metabolism and Composition of Fish Hindgut Symbiotic Communities
The work presented in this thesis shows that in addition to their role in providing energy, microbial communities of marine herbivorous fishes may provide a de novo source of protein for the host, via nitrogen fixation. Expand
Distribution of nitrogen fixation and nitrogenase-like sequences amongst microbial genomes
A new criterion for computational prediction of nitrogen fixation is proposed: the presence of a minimum set of six genes coding for structural and biosynthetic components, namely NifHDK and NifENB. Expand
Cloning, Overexpression, and Characterization of a Metagenome-Derived Phytase with Optimal Activity at Low pH.
Purified protein of the recombinant phytase demonstrated an activity for phytic acid of 298 ± 17 μmol P/min/mg, at the pH optimum of 2.0 with the temperature of 37 °C, which suggests that thephytase could possess improved adaptability to the low pH condition caused by the gastric acid in livestock and poultry stomachs.

Bioelectrochemical and Conventional Bioremediation of Environmental Pollutants
Use of BESs to remediate chemically diverse pollutants has proven effective; however, there remains a need to overcome limitations with BES process start up time, scale up and design, remote monitoring and the cost of B ES electrodes and catalysts. Expand
Structural and functional analysis of the bacterial root microbiota of Arabidopsis thaliana and relative species.
It is established that members of the Rhizobial population act as plant growth-promoting rhizobacteria that affect primary root growth under various nutrient conditions and A. thaliana accessions. Expand
Bacterial communities and chemical parameters in soils and coastal sediments in response to diesel spills at Carlini Station, Antarctica.
This response at community level suggests that the cold-adapted indigenous microbiota in soils of the West Antarctic Peninsula have a high potential for bioremediation and can support soil cleaning actions in the ecosystem. Expand
Microbial Remediation of Organometals and Oil Hydrocarbons in the Marine Environment
Marine environments are exposed to pollution that mostly results from human activities. Organometals and oil hydrocarbons are among the most hazardous pollutants. In surface waters and along theExpand
Orchard Conditions and Fruiting Body Characteristics Drive the Microbiome of the Black Truffle Tuber aestivum
The results show, regardless of the geographical location considered, the existence of heterogeneous bacterial communities within T. aestivum fruiting bodies that are dominated by three bacterial classes, and indicate that factors shaping microbial communities within truffle fruiting body differ across local conditions. Expand
Quantitative divergence of the bacterial root microbiota in Arabidopsis thaliana relatives
It is shown that differences in root microbiota profiles between these hosts are largely quantitative and that host phylogenetic distance alone cannot explain the observed microbiota diversification, and reveals a largely conserved and taxonomically narrow root microbiota, which comprises stable community members belonging to the Actinomycetales, Burkholderiales, and Flavobacteriales.

The genome of Polaromonas naphthalenivorans strain CJ2, isolated from coal tar-contaminated sediment, reveals physiological and metabolic versatility and evolution through extensive horizontal gene transfer.
Analysis of the genome of the aromatic hydrocarbon-degrading, facultatively chemolithotrophic betaproteobacterium, Polaromonas naphthalenivorans strain CJ2 revealed strong trends in shared heredity between strain CJ1 and other members of the Comamonadaceae and Burkholderiaceae, and three different terminal oxidase genes were found, suggesting adaptation by strains CJ2 to variable aerobic and microaerobic conditions.

Polaromonas naphthalenivorans sp. nov., a naphthalene-degrading bacterium from naphthalene-contaminated sediment.
Comparative 16S rDNA analysis indicated that strain CJ2T is related to the family Comamonadaceae and that the nearest phylogenetic relative was Polaromonas vacuolata 34-PT (97.1% similarity). Expand

Microorganisms maintain the biosphere by catalyzing biogeochemical processes, including biodegradation of organic chemical pollutants. Yet seldom have the responsible agents and their respectiveExpand
Burkholderia, a Genus Rich in Plant-Associated Nitrogen Fixers with Wide Environmental and Geographic Distribution
The results obtained show that many diazotrophic Burkholderia isolates analyzed showed phenotypic and genotypic features different from those of the known N2-fixing species B. vietnamiensis as well as from B. kururiensis, a bacterium identified in the present study as a diazOTrophic species. Expand
Whole-genome analysis of the ammonia-oxidizing bacterium, Nitrosomonas eutropha C91: implications for niche adaptation.
Analysis of the structure and inventory of the genome of Nitrosomonas eutropha C91 revealed distinctive features that may explain the adaptation of N. eUTropha-like bacteria to N-saturated ecosystems, and several distinctive properties of the N.E. eutrapha genome that are supportive of niche specialization.

It is suggested that certain monomeric phenols can support nitrogenase activities in many carbon-limited soil environments. Expand
Multiple genome sequences reveal adaptations of a phototrophic bacterium to sediment microenvironments
This work suggests that against a backdrop of metabolic versatility that is a defining characteristic of Rhodopseudomonas, different ecotypes have evolved to take advantage of physical and chemical conditions in sediment microenvironments that are too small for human observation. Expand
