However, both direct and
syntrophic oxidation may be active in the environment; a
robust model should account for all major pathways.
Injection of acetate or ethanol into aquifers is an emerging
strategy for stimulating microbial uranium reduction and
limiting groundwater contamination To predict how ethanol amendment impacts
subsurface environments, we describe here a biogeochemical
reaction model of ethanol metabolism. This model is based
on microbial physiology and differs from recent efforts: it
accounts for a full suite of microbial metabolisms that degrade ethanol both directly and syntrophically, and it
considers both kinetic and thermodynamic controls on the
metabolisms
