Results from kinetic reaction path model of sulfate reducers and methanogens

Summary edit

Description
English: Results of a kinetic reaction path model of sulfate reduction and methanogenesis. Graphs show variation over time in (A) thermodynamic potential factors (FT), (B) biomass abundances [X], (C) reaction rates, and (D) concentrations of sulfate (SO42-), sulfide (S(-II)), acetate (CH3COO-), and methane (CH4). Reaction rates and population dynamics were simulated according to the Jin and Bethke rate law (2007, 2005, 2003, 2002) using kinetic parameters from Jin and Roden (2011). The model was calculated using the flush configuration in the React module of The Geochemist’s Workbench. The volume of water in the system is replaced 20 times over a 400-day simulation period, giving the water a residence time of 20 days. Water entering the system has neutral pH and contains 0.1 mM acetate, 0.2 mM sulfate, 0.5 mM bicarbonate, and 1 mM each of sodium and chloride.
