MINERAL SURFACE CONTROLS ON THE DIAGENETIC TRANSPORT OF OXALATE AND ALUMINUM

Fein J.B.; Brady P.V. (1995)

The importance of adsorption is virtually unknown at temperatures of > 25°C. This study indicates that interactions between organic acids and mineral surfaces may control Al transport during clastic diagenesis. Oxalate ...
MOLECULAR SIMULATIONS OF METAL ADSORPTION TO BACTERIAL SURFACES

Johnson K.J.; Cygan R.T.; Fein J.B. (2006)

The atomic-scale interactions that occur between cations and the metal-binding cell wall components common to many gram-positive bacteria were investigated using molecular simulations techniques. We examined the adsorption ...
PROTON AND CD ADSORPTION ONTO NATURAL BACTERIAL CONSORTIA: TESTING UNIVERSAL ADSORPTION BEHAVIOR

Borrok D.; Fein J.B.; Kulpa C.F. (2004)

Bacterial surface adsorption can control metal distributions in some natural systems, yet it is unclear whether natural bacterial consortia differ in their adsorption behaviors. In this study, we conduct potentiometric ...
PROTON BINDING TO HUMIC ACIDS AND SORPTION OF PB(II) AND HUMIC ACID TO THE CORUNDUM SURFACE

Boily J.F.; Fein J.B. (2000)

An experimental investigation of proton binding to a humic acid, and of the co-adsorption of humic acid and Pb(II) to the corundum surface was conducted in 0.01 M NaNO3. We attempt to model the acid-base properties of the ...
QUANTIFYING THE EFFECTS OF BACTERIA ON ADSORPTION REACTIONS IN WATER-ROCK SYSTEMS

Fein J.B. (2000)

This paper reviews the investigations that quantify metal-bacteria, organic-bacteria, and bacteria-mineral adsorption reactions. The studies are divided into the two main approaches used to quantify adsorption: bulk ...
TERNARY INTERACTIONS IN A HUMIC ACID-CD-BACTERIA SYSTEM

Wightman P.G.; Fein J.B. (2001)

Humic acid adsorption onto the bacterial surface of Bacillus subtilis was measured with and without Cd, as a function of pH and humic-bacteria-Cd ratios. These experiments tested for the existence of ternary interactions ...
THE EFFECT OF AQUEOUS COMPLEXATION AND GIBBSITE SURFACE SITES ON THE DECARBOXYLATION RATE OF MALONATE

Fein J.B.; Gore N.; Marshall D.; Yassa L.; Loch A.; Brantley S.L. (1995)

The effect of metal-malonate complexation on the decarboxylation rate of malonate was studied by comparing the decarboxylation rates observed for malonate-bearing solutions with and without aqueous metal at 55, 80, and ...
THE EFFECT OF CADMIUM ON FULVIC ACID ADSORPTION TO BACILLUS SUBTILIS

Frost P.C.; Maurice P.A.; Fein J.B. (2003)

The effects of Cd on the adsorption of an aquatic fulvic acid (FA) to the surface of Bacillus subtilis were investigated from pH 2.5 to 7.0, at fixed ionic strength (0.1 M NaClO4) and at ambient temperature (~22 °C). Cd ...
THE EFFECT OF FE ON SI ADSORPTION BY BACILLUS SUBTILIS CELL WALLS: INSIGHTS INTO NON-METABOLIC BACTERIAL PRECIPITATION OF SILICATE MINERALS

Fein J.B.; Scott S.; Rivera N. (2002)

Si adsorption onto Bacillus subtilis and Fe and Al oxide coated cells of B. subtilis was measured both as a function of pH and of bacterial concentration in suspension in order to gain insight into the mechanism of association ...
X-RAY ABSORPTION FINE STRUCTURE DETERMINATION OF PH-DEPENDENT U-BACTERIAL CELL WALL INTERACTIONS

Kelly S.D.; Kemner K.M.; Fein J.B.; Fowle D.A.; Boyanov M.I.; Bunker B.A.; Yee N. (2002)

X-ray absorption fine structure (XAFS) measurements was used at the U L3-edge to directly determine the pH dependence of the cell wall functional groups responsible for the absorption of aqueous UO22+ to Bacillus subtilis ...
