16S ribosomal DNA amplification for phylogenetic study
TLDR
By use of this method, the phylogenetic study of extremely fastidious or highly pathogenic bacterial species can be carried out without the need to culture them.
Complete genome sequence of the metabolically versatile photosynthetic bacterium Rhodopseudomonas palustris
TLDR
The genome sequence of R. palustris is described, which reveals genes that confer a remarkably large number of options within a given type of metabolism, including three nitrogenases, five benzene ring cleavage pathways and four light harvesting 2 systems.
Distinct Microbial Communities within the Endosphere and Rhizosphere of Populus deltoides Roots across Contrasting Soil Types
TLDR
Analysis of microbial communities from the root endophytic and rhizospheric habitats of Populus deltoides in mature natural trees from both upland and bottomland sites in central Tennessee demonstrates that root endophical communities are distinct assemblages rather than opportunistic subsets of the rhizosphere.
Effects of Engineered Cerium Oxide Nanoparticles on Bacterial Growth and Viability
TLDR
A multianalytical approach to understand the interactions of synthesized nanoparticles with bacterial systems is initiated initially on cerium oxide nanoparticles and model bacteria in order to evaluate characterization procedures and the possible fate of such materials in the environment.
A cluster of bacterial genes for anaerobic benzene ring biodegradation.
TLDR
Physiological data and DNA sequence analyses indicate that the benzoate pathway consists of unusual enzymes for ring reduction and cleavage interposed among enzymes homologous to those catalyzing fatty acid degradation.
Silver nanocrystallites: biofabrication using Shewanella oneidensis, and an evaluation of their comparative toxicity on gram-negative and gram-positive bacteria.
TLDR
The biosynthesis of extracellular silver-based single nanocrystallites of well-defined composition and homogeneous morphology utilizing the gamma-proteobacterium, Shewanella oneidensis MR-1, upon incubation with aqueous silver nitrate solution is reported, with implications for the potential uses of Ag nanomaterials and for their fate in biological and environmental systems.
Initial Phases of Biofilm Formation in Shewanella oneidensis MR-1
TLDR
Investigating the molecular basis of biofilm formation in S. oneidensis biofilms developing on glass surfaces in a hydrodynamic flow chamber system provides a basis for understanding microbe-mineral interactions in natural environments.
Cytotoxicity induced by engineered silver nanocrystallites is dependent on surface coatings and cell types.
TLDR
The results demonstrate that the physical/chemical properties of the silver nanoparticles including surface charge, differential binding and aggregation potential, which are influenced by the surface coatings, are a major determining factor in eliciting cytotoxicity and in dictating potential cellular interactions.
Twenty-One Genome Sequences from Pseudomonas Species and 19 Genome Sequences from Diverse Bacteria Isolated from the Rhizosphere and Endosphere of Populus deltoides
ABSTRACT To aid in the investigation of the Populus deltoides microbiome, we generated draft genome sequences for 21 Pseudomonas strains and 19 other diverse bacteria isolated from Populus deltoides
Diversity of microbial toluene degradation pathways.
TLDR
Toluene is found naturally in petroleum and coal, and is a major component of gasoline, and has been detected in cigarette smoke.
