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.
