Title: Formation and Reactivity of Biogenic Iron Minerals

Abstract

In the current study we aimed to determine how the cell surface polymers, such as lipopolysaccharide (LPS) and capsular material, of a number of strains of Shewanella influenced surface proton binding behavior. An investigation of this kind is pertinent as surface proton binding site reactivity may influence a number of important eco-physiological factors. For example, proton binding sites may sequester Fe2+, as well as other metals like Ni2+, and thus inhibit the supply and metabolic reduction of Fe3+.(Parmar et al. 2001) Further understanding the cell surface reactivity of Shewanella is also important as this may influence the ability of the microorganism to adhere and interact with metal oxides and hydroxides. This study combined acid-base titration analyses to determine proton binding behavior with SDS-PAGE analysis of LPS.
