Gibbs Energy Dynamic Yield Method (GEDYM): Predicting microbial growth yields under energy-limiting conditions
Smeaton, Christina M.; Van Cappellen, Philippe (Elsevier, 2018-11-15)Biomass-explicit biogeochemical models assign microbial growth yields (Y) using values measured in the laboratory or predicted using thermodynamics-based methods. However, Y values are rarely measured under the low energy ... -
Iron Isotope Fractionations Reveal a Finite Bioavailable Fe Pool for Structural Fe(III) Reduction in Nontronite
Shi, Bingjie; Liu, Kai; Wu, Lingling; Li, Weiqiang; Smeaton, Christina M.; Beard, Brian L.; Johnson, Clark M.; Roden, Eric E.; Van Cappellen, Philippe (American Chemical Society, 2017-08-16)We report on stable Fe isotope fractionation during microbial and chemical reduction of structural Fe(III) in nontronite NAu-1. Fe-56/Fe-54 fractionation factors between aqueous Fe(II) and structural Fe(III) ranged from ...
