Regulatory dynamics of microbial communities

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
H Wiley
Project type
Large-Scale EMSL Research
This is a proposal to conduct work in EMSL in support of the Foundational Scientific Focus Area (FSFA) research program at Pacific Northwest National Laboratory. This large-scale research program…

Environmental Sensing, Metabolic Response,Regulatory Network (PNNL 42654, BES)

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Fredrickson
Project type
Exploratory Research
HPLC analysis and quanitation of organic acids is a critical tool to track metabolic changes during growth in microbial cultures. Because are own HPLC system has ended it's useful life, Tom…

Grand Challenge in Biogeochemistry

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Fredrickson
Project type
Grand Challenge
Do multiheme cytochromes associated with the outer membrane of metal reducing bacteria (mtrC in Shewanella oneidensis and omcB in Geobacter sulfurreducens, for example) transfer electrons to Fe(III)…

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Fredrickson
SPECIFIC AIMS: The overall objective of the proposed research is to acquire a predictive understanding of how microbial interactions impart stability, fitness, and functional efficiency to microbial…

Microbial Reduction of Illite and Glauconite

Lead Institution
Miami University
Principal Investigator
Hailiang Dong
Project type
Exploratory Research
This project investigates reduction of Fe(III) in structure of sedimentary illite and glauconite by Shewanella oneidensis CN32, and possible implications for bioremediation and subsurface microbial…

Observation of Biogenic Nano-scaled Wire-like Arsenic Sulfide Mineral

Lead Institution
Gwangju Institute of Science and Technology (GIST)
Principal Investigator
Ji-hoon Lee
Project type
Capability Research
A facultative anaerobic rod, dissimilatory iron-reducing bacterium, Shewanella sp. strain HN-41, which was isolated from a oil shale rock fragment collected at a tidal in Haenam, South Korea, was…

Shewanella oneidensis

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
Mary Lipton
Project type
Exploratory Research
Bacterial strains such as Shewanella oneidensis strain MR-1 are key organisms in the bioremediation of metals due to their ability to enzymatically reduce and precipitate a diverse range of heavy…

Quantifying the functional and structural states of dynamic microbial communities

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Fredrickson
Project type
Large-Scale EMSL Research
The overall goal of this proposal is to provide a quantitative framework in which to compare species-resolved patterns of gene expression, allowing comparison of the effects of perturbations of…
