Subsurface Biogeochemical Research Program

Subsurface Biogeochemistry Research Timeline

  • 2015 - 2016:   Discovered new microbial species using genomic techniques and that interactions among the microbial community members drive biogeochemical cycles.  See LBNL News Center for more.
  • 2015 - 2016:   Developed E4D-RT, a real-time 4D subsurface imaging technology (2016 R&D 100 Award). See this news item for more.
  • 2015 - 2016:   Demonstrated, through high performance computing, that the availability of water to vegetation is key for understanding the flux of terrestrial water to the atmosphere. See this highlight for more.
  • 2014 - 2015:   Discovered ultra-small bacterial cells. See LBNL ESD News for more.
  • 2014 - 2015:   Demonstrated that subsurface microbial communities can serve as quantitative biosensors of subsurface geochemical conditions. See this highlight for more.
  • 2013 - 2014:   Discovered that in alkaline aquifers, some bacteria can use elemental sulfur to indirectly reduce iron, which can then indirectly affect contaminant mobility in the subsurface. See this highlight for more.
  • 2013 - 2014:   Discovered that multiple species of bacteria convert elemental mercury to toxic methylmercury. See this BER highlight for more.
  • 2013 - 2014:   Demonstrated feasibility of reducing technetium transport in groundwater by reacting technetium with zero-valent iron to form technetium sulfide. See EMSL News for more.
  • 2012 - 2013:   Demonstrated that proteins in the cell wall of some bacteria produce an electric current when in contact with a mineral surface, thereby allowing the bacteria to “breathe” the iron in the mineral. See EMSL News for more.
  • 2012 - 2013:   Discovered the genes for bacterial mercury methylation. See this BER highlight for more.
  • 2011 - 2012:   Discovered that binding of uranium to microbial biopolymers is an essential step for the efficient reduction of uranium (VI) in aquifers. See this highlight for more.
  • 2011 - 2012:   Developed new approach to model the chemical interactions of plutonium with minerals and biological molecules using density functional theory. See this highlight for more.
