Description

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 ... continued below

This study combined acid-base titration analyses to determine proton binding behavior with SDS-PAGE analysis of LPS.
