Understanding the controls on bacterial surface sulfhydryl site concentrations is crucial for modeling the effects of bacterial cells on the fate and transport of chalcophile metals in the environment. In this study, we investigate the effects of cha

The adsorption of metal onto archaea could affect metal behavior and bioavailability in hypersaline environments where archaea represent the dominant life form. However, the mechanism and thermodynamics of metal adsorption onto halophilic archaea are

Tellurium (Te) is an emerging contaminant and its chemical transformation in the environment is strongly influenced by microbial processes. In this study, we investigated the adsorption of tellurite [Te(IV), TeO32-] onto the common soil bacterium Bac

Although carboxyl and phosphoryl functional groups within the bacterial cell envelope and on bacterial extracellular polymeric substance (EPS) molecules are the most abundant metal binding sites, recent studies suggest that sulfhydryl sites control t

Bacteria–Au interactions control the fate of Au in a variety of geologic systems. Although previous studies have determined that non-metabolizing Bacillus subtilis cells can remove Au(III) from sol...

In this study, we measured the effect of EPS on Cd and proton adsorption behaviors by measuring the extent of adsorption onto biomass with and without the EPS removed via a cation exchange resin. W...

Over the past 40 years, laboratory experiments involving single metal-single sorbent systems have been conducted in order to determine thermodynamic stability constants for metal-bacteria and metal-mineral surface complexes. The component additivity

The mechanism of metal adsorption onto bacteria can change as a function of metal loading of the binding sites, and therefore the mechanisms of adsorption and the thermodynamic stability constants for the important bacterial surface complexes must be
