Imaging and Monitoring the Initial Stages of Biofilm Formation

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

R. Shane Addleman

As outlined below, the goal of this study to apply an integrated, multi-faceted approach to the analysis of the initial molecular and cellular processes involved with cell adhesion, colonization, and…

Analyzing the soil microbial central C metabolic network under contrasting conditions of carbon availability and oxygen concentration in a Florida landscape

Lead Institution

Northern Arizona University

Principal Investigator

Paul Dijkstra

Project type

Large-Scale EMSL Research

Understanding how environmental factors affect soil C cycling processes is important, as soil is the largest C pool in terrestrial ecosystems, and any change in its size may feed back to the…

Microbial CH4 and CO2 Fluxes and C Stabilization Mechanisms in Soils

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Vanessa Bailey

Project type

Large-Scale EMSL Research

Current versions of the Community Land Model (CLM) do not represent the soil biogeochemical mechanisms controlling the fluxes of CO2 and CH4, two known greenhouse gases (GHG).. This failure is…

Influence of Rhizosphere Iron on Carbon Cycling in a Wetland Environment

Lead Institution

Savannah River National Laboratory

Principal Investigator

Daniel Kaplan

Project type

Large-Scale EMSL Research

About 20% of the earth's carbon resides in wetlands and another 20% of the organic carbon in sediment is associated to reactive iron phases, either existing in wetlands or elsewhere. This…

Investigating mechanisms for negative priming of soil organic carbon by pyrogenic carbon using NanoSIMS and LA-AMS

Lead Institution

Cornell University

Principal Investigator

Johannes Lehmann

Project type

Large-Scale EMSL Research

Reduced turnover rate (often referred to as “negative priming”) of soil organic carbon (SOC) by pyrogenic black carbon (pyC) has the potential to have dramatic long-term effects on soil carbon stocks…

How do temperature and soil organic matter inputs mediate the organic molecular composition of soils?

Lead Institution

University of Oregon

Principal Investigator

Scott Bridgham

Project type

Exploratory Research

The potential release of stored soil carbon under a warming climate will be at least partially dependent on the temperature response of soil organic matter (SOM) mineralization. However, it has…

The role of protein-mineral interactions for protein oxidation and hydrolysis

Lead Institution

Oregon State University

Principal Investigator

Markus Kleber

Project type

Exploratory Research

We intend (1) to establish the molecular range of modifications to protein integrity and protein structure as such protein becomes associated with mineral surfaces and (2) to determine how mechanisms…
