Lead Institution: Michigan State University
Principal Investigator: Lisa Tiemann
The process by which atmospheric N2 is converted into ammonia by bacteria is energetically expensive. Diazotrophs living in the rhizosphere (root surface and associated soil) of bioenergy crops, such as switchgrass, perform free-living nitrogen-...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Brian Riley
The primary goal of this user proposal is to gain access to the unique instruments at EMSL that we need to identify and spatially resolve light elements such as Li and B in the presence of other surrogate radionuclides in a variety of waste forms....
Lead Institution: State University of New York at Stony Brook
Principal Investigator: Daniel Knopf
Atmospheric ice nucleation represents one of the least understood atmospheric processes, hampering prediction of cloud processes and climate. Whereas the aerosol community has widely conducted aerosol-cloud condensation nuclei studies to evaluate...
Lead Institution: Montana State University
Principal Investigator: Robin Gerlach
Developing algal-based biofuels and bioproducts is one of the goals of the Department of Energy-Bioenergy Technology Office (DOE-BETO). The work proposed here focuses on an algal strain, tentatively identified as Chlorella sorokiniana and obtained...
Lead Institution: University of Washington
Principal Investigator: Sharon Doty
Native poplar (Populus) plants have a diverse microbiota including endophytes, microorganisms that live within plants, some of which can fix atmospheric nitrogen (N2) into forms of nitrogen (N) available to their host plant. These beneficial...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Jason McDermott
The goal of this project is to attain a systems level understanding of the soil microbiome and its phenotypic response to changing moisture through a tractable, spatially explicit examination of the molecular and ecological interactions occurring...
Lead Institution: Princeton University
Principal Investigator: Tullis Onstott
The specific aim of this Large-Scale EMSL proposal is to image the metabolic interactions of deep subsurface anaerobic CH4-cycling microbial consortia: 1) at high pressure and temperature; 2) at high temperature and salinity, and 3) during in situ...
Lead Institution: University of Arizona
Principal Investigator: Malak Tfaily
Interactions at the plant-soil-microbe nexus are difficult to track given the complex networks of species and metabolites involved, in addition to the general challenges to studying heterogeneous and uncontrolled ecosystems. Here, we propose to...
Lead Institution: Washington University in St. Louis
Principal Investigator: Daniel Giammar
Redox-driven recrystallization of metal oxides is an exciting environmental phenomenon that can influence biogeochemical cycles of both nutrients and contaminants. This phenomena occurs in systems with redox gradients or fluctuating redox...
Lead Institution: National Renewable Energy Laboratory
Principal Investigator: Bryon Donohoe
Specific Aim: Image spatial 13C enrichment into Pseudomonas putida intercellular nanotubes and/or associated outer membrane vesicles during static cultivations on lignin-derived aromatic compounds. Resource Request: One week of NanoSIMS imaging and...
