ABSTRACT
The microbe-metal interactions are considered effective tools for
removal of metals from contaminatedwaters. Direct interactions be-
tween microorganisms and metals include the adsorption onto mi-
crobial cells, accumulation, and conversion and precipitation driven
by microbially mediated reactions (Fig. 1.1). In addition, the min-
eral precipitates (e.g., Fe and Mn oxides) occurring at microbial cell
surfaces often act as adsorbents, oxidants or reductants, and cata-
lysts, owing to their high specific surface area and high reactivity.
