Title :

Microbe-Mineral Interface in Contaminated Environments

Description :

Mission Challenge of Environmental Remediation Sciences Division Microbe-Mineral Interface in Contaminated Environments Biogeochemical processes driven by interactions at the microbe-mineral interface in soils and sediments influence contaminant behavior. These reactions occur at the level of the individual cell or groups of cells, forming an architecture assembled against the mineral surface. The cells interact with each other and the mineral surface, creating a dynamic, microscale domain that controls the kinetics of biogeochemically mediated reactions. Before large-scale restoration strategies can be implemented, such processes must be better understood to predict contaminant transport in situ under natural and induced conditions. (“Induced conditions” refers to the addition of nutrients, oxygen, or other electron donors and acceptors to increase microbial activity.) Achieving this level of knowledge requires new tools to characterize and resolve fundamental phenomena at the molecular, cellular, and community levels. Microbial information must be integrated with the subsurface strata’s geochemical characterization and the system’s hydrological properties at the sediment mineral and pore scales.
