Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: James Moran
Plant root exudates provide a significant carbon (C) source for rhizosphere microbial communities. In return, these communities help mobilize nutrients needed for plant growth. For instance, biogeochemical cycling of phosphorus (P) in the...
Lead Institution: Los Alamos National Laboratory
Principal Investigator: Ping Yang
The goal of this proposal is to characterize the molecular mechanisms associated to the a Mn2(II,II) core of the SoxB protein. This protein plays a central role in the sulfur oxidizing catalytic process used by bacteria to perform aerobic...
Lead Institution: Colorado State University
Principal Investigator: Kelly Wrighton
This proposal focuses on understanding the constraints on methane metabolism in freshwater temperate wetland soils, as these systems currently represent the largest source of natural methane emissions to the atmosphere. The overarching goal of our...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Mychailo Toloczko
Current reactor concepts call for fuel cladding and duct to withstand up to as much as 500 dpa of neutron irradiation. Achieving such dose levels using neutrons is totally impractical due to the unavailability of suitable irradiation sources. As...
Lead Institution: Lawrence Livermore National Laboratory
Principal Investigator: Yongqin Jiao
Lanthanides are composed of 15 metallic chemical elements (La-Lu). Combined with Sc and Y, they are often collectively known as the rare earth elements (REEs). Although lanthanides are ubiquitous in the environment, they have long been regarded as...
Lead Institution: Stanford Linear Accelerator Center
Principal Investigator: Kristin Boye
Redox conditions and related switches in microbial metabolic activities exert primary control over the stability of carbon, nutrient, and contaminant stocks in alluvial systems, such as floodplains. This project focuses on a uranium-contaminated...
Lead Institution: Oregon State University
Principal Investigator: Kelsey Stoerzinger
Iron (Fe)-containing minerals exert a significant influence on soil and sediment geochemistry, such as the cycling of nitrogen (N) and phosphorus (P) nutrients in the bioavailable form of dissolved oxyanions. Initial efforts have been made to...
Lead Institution: Lawrence Livermore National Laboratory
Principal Investigator: Ty Samo
Attachment between phototrophic microalgae and heterotrophic bacteria is an integral yet understudied facet of microbial ecology. Such inter-kingdom cooperative partnerships have important consequences for biogeochemical cycling, ecosystem function...
Lead Institution: University of Manitoba
Principal Investigator: Michael Schindler
Airborne particulate matter (PM) - suspended solid particles with diameters between a few nanometers (nm) and several micrometers - has always been a constituent of the Earth's atmosphere. Man-made PM accounts for only 2-3% of the particle mass...
Lead Institution: State University of New York at Stony Brook
Principal Investigator: Daniel Knopf
Ocean waters, which cover 71% of the Earth's surface, contain dissolved organic carbon (DOC) including lipids, humics and organic acids, and free macromolecules, the precursor material for the formation of nano- to micro-sized polysaccharidic...
