Title :

A Revolutionary Whole-Genome Perspective

Description :

Meshing GTL’s Approach to ERSD’s Challenges A Revolutionary Whole-Genome Perspective Genomic information on cellular metabolism can be incorporated as physiological modules into computer (in silico) models to better understand metabolism, predict cell responses under different environmental conditions, and improve contaminant fate and transport models. Microbes already sequenced by DOE and under intense analysis in GTL have been detected in Environmental Remediation Sciences Division (ERSD) studies of in situ immobilization techniques in the subsurface of uranium-contaminated aquifers. These organisms are closely related to the GTL organisms on which existing physiological modules are based. As additional sequenced organisms become available, similar in silico models could be developed to more accurately model multispecies phenomena. These include syntrophic relationships, anaerobic degradation consortia, and shifts in the dominant terminal electron accepting process (called TEAP) observed in sediments. Although progress is being made, many challenges remain in placing fundamental physiological knowledge in the context of the dynamic flow and transport regimes characteristic of DOE sites.
