Modeling microbial processes in porous media

摘要: The incorporation of microbial processes into reactive transport models has generally proceeded along two separate lines investigation: (1) bacteria as inert colloids in porous media, and (2) the biodegradation dissolved contaminants by a stationary phase bacteria. Research over last decade indicated that these are closely linked. This linkage may occur when change metabolic activity alters attachment/detachment rates to surfaces, either promoting or retarding bacterial groundwater-contaminant plume. Changes activity, turn, controlled time exposure microbes electron acceptors/donor other components affecting activity. Similarly, can affect reversibility attachment, depending on residence active microbes. Thus, improvements quantitative analysis subsurface biota necessitate direct linkages between substrate availability, growth, rates. requires both detailed understanding biological robust representations be tested experimentally. paper presents an overview current approaches used represent physicochemical with new conceptual link partitioning microorganism aqueous solid phases.
