Yee N.; Fowle D.A.; Ferris F.G. (2004)In this study, we conducted electrophoretic mobility, potentiometric titration, and metal sorption experiments to investigate the surface charge characteristics of Bacillus subtilis and the electrostatic interactions between ...

Boyanov M.I.; Kelly S.D.; Kemner K.M.; Bunker B.A.; Fein J.B.; Fowle D.A. (2003)The local atomic environment of Cd bound to the cell wall of the gram-positive bacterium Bacillus subtilis was determined by X-ray absorption fine structure (XAFS) spectroscopy. Samples were prepared at six pH values in ...

Fowle D.A.; Fein J.B. (1999)In order to test the ability of a surface complexation approach to account for metal-bacteria interactions in near surface fluid-rock systems, we have conducted experiments that measure the extent of adsorption in mixed ...
-
Fowle D.A.; Fein J.B. (2000)This study tests the reversibility of metal-bacteria interactions by comparing estimated extents of desorption based on surface complexation modeling, to those we observed in the experimental adsorption/desorption systems. ...

Johari Pannalal S.; Crowe S.A.; Cioppa M.T.; Symons D.T.A.; Sturm A.; Fowle D.A. (2005)Room-temperature magnetic techniques are rapidly becoming an important tool for the discrimination and quantification of minerals in a broad range of geological, environmental and extraterrestrial materials. The utility ...

Daughney C.J.; Fowle D.A.; Fortin D. (2001)Several recent studies have applied surface complexation models to quantify metal adsorption by bacterial surfaces. Although these models can account for the effects of many abiotic variables (such as pH and ionic strength), ...

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 ...
