Chromium (III) binding by exopolymeric substances (EPS) isolated from Pseudomonas
putida P18, Pseudomonas aeruginosa P16 and Pseudomonas stutzeri P40 strains were
investigated by the determination of conditional stability constants and the concentration of
functional groups using the ion-exchange experiments and potentiometric titrations.
Spectroscopic (EXAFS) analysis was also used to obtain information on the nature of Cr (III)
binding with EPS functional groups. The data from ion-exchange experiments and …

Laboratory batch sorption and column experiments were performed to investigate the effects
of microbial EPSs isolated from Pseudomonas putida P18, Pseudomonas aeruginosa P16
and Pseudomonas stutzeri P40 on Cr (III) mobility in heterogeneous subsurface soils. Our
batch and column results indicate that microbial EPS may have a pronounced effect on Cr
(III) sorption and transport behavior depending on system conditions (eg, pH, type of EPS).
While EPS had no effect on Cr (III) sorption at pH< 5, it led to a significant decrease in Cr (III) …
