An Fe, S-Sustained Subsurface Biosphere: Insights Through Linking Geochemistry and Genomics
When: November 24, 2003 12AM PST
Our NAI team’s research efforts center around the question of the habitability of Mars over Martian history, the possibility that life evolved there, and the types of biomes that may be present. The focus of our planned effort is broad. However, in this presentation, I will focus on geomicrobiological aspects of this work that relate to iron and sulfur-based ecosystems that flourish in the subsurface, independent of photosynthesis. In particular, the application of genomics to study microbial community structure and function will be discussed.
