B080:
Using “Omics”-based Approaches to Link Biotic and Abiotic Processes in Subsurface Environments





Session ID#: 26205

Session Description:
The development of “omics” tools has revolutionized geomicrobiology and biogeochemistry, greatly enhancing our ability to study ecosystem processes in natural environments. As omics techniques preclude the need for culturing, they are especially pertinent to the study of the deep subsurface, where microbial turnover rates may be on the order of thousands of years, and the natural environment is difficult if not impossible to replicate in the laboratory. Furthermore, overlapping biochemical and geochemical processes in the deep biosphere result in an intriguing but confounding boundary between the living and nonliving world. Understanding the relationship between microbial metabolism and geochemistry is vital to our understanding of microbial and systems ecology, and the transition from abiotic to biotic chemistry bears astrobiological significance as well. This session will explore the use of omics-based emergent technologies (including metagenomics, metatransciptomics, proteomics, and metabolomics) to map the intersection between biotic and abiotic processes in the deep subsurface.
