Ecosphere to Biosphere Modeling - Final CAN-3 Report
Project Summary
We have created a working model of a microbial mat called MBGC (for Microbial Biogeochemistry). The model examines the internal cycling of oxygen, carbon, and sulfur through a complex microbial ecosystem that may be similar to those found on early earth.

Project Progress
We continued to work on the changes to the carbon cycle in the model and how they affect the organisms that depend on the breakdown of photosynthate by fermentation. Specifically, the novel fermentation algorithm has consequences to the timing of sulfate reducing bacteria metabolism.
