Quantifying Metal Adsorption onto Bacteria Mixtures: A Test and Application of the Surface Complexation Model
- Biology
- 2003
The metal binding constants determined with the bacteria mixtures in this study are similar to the binding constants that have previously been measured for B. subtilis, suggesting that adsorption constants can be estimated using thermodynamic parameters determined for a limited number of bacterial species.

XAFS has been used to resolve whether binding sites determined for single species systems are responsible for adsorption in more complex natural bacterial assemblages, and can potentially have very high impact on the modeling of the complex bacterial systems in realistic geological settings, leading to further refinement and development of robust remediation strategies for metal contamination at macroscopic level.

The authors solve for stability constants describing metal adsorption onto distinct functional groups on the bacterial cell walls and find that these stability constants vary substantially but systematically between the two bacterial species at the two different ionic strengths.
Characterizing Heterogeneous Bacterial Surface Functional Groups Using Discrete Affinity Spectra for Proton Binding

A quantitative investigation of the types and densities of proton binding sites on a bacterial surface, Bacillus subtilis, from replicate acid−base titrations on bacteria at two ionic strengths indicated less variability than has been suggested for bacterial surfaces.
