Quantitative prediction of microbial metabolism is
critical to understanding the chemistry of natural environments, as well as natural attenuation and engineered
bioremediation of subsurface contaminants. Many biogeochemical reaction models have been developed for simulating microbial degradation of natural and anthropogenic
organic compounds Most models assume that organic matter oxidation is coupled to the reduction of O2, nitrate, metal oxides, sulfate, and
other electron acceptors either directly or syntrophically
