The cell walls of bacteria are known to adsorb a variety of metals, and thus they may control metal mobilities in many low-temperature aqueous systems. In order to quantify metal adsorption onto bacterial surfaces, recent ...

Mobilization of contaminant Pb and other cations from a weathered andesite was examined by conducting water-rock leaching experiments to measure release rates of the major and minor elements found in the bulk rock. Experiments ...

The surface water of the marine environment has traditionally been viewed as a nitrogen (N) limited habitat, and this has guided the development of conceptual biogeochemical models focusing largely on the reservoir of ...

In this study, we investigate the effects of bacteria on metal transport through mineral-filled columns, and how the effect varies with pH and mineralogy. We measured Bacillus subtilis and aqueous Cd transport through ...

In order to examine the effects of Bacillus subtilis on rates and extents of gibbsite dissolution, we conducted batch-type dissolution experiments with viable, non-viable, and no bacteria. Dissolved Al and organic carbon ...

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 ...

Scanning and transmission electron microscopy (SEM/TEM) were used to investigate the spatial arrangement of chains of magnetosomes in cells of two morphologically different types of magnetotactic bacteria which possess at ...

This study characterizes the surface chemistry and morphology of poorly crystalline iron sulfides precipitated in a chemically defined growth media for sulfate-reducing bacteria. The precipitates were analyzed by X-ray ...

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 ...
