Transport of subsurface bacteria in porous media. Final report
The aims of our project have not changed significantly since the original proposal. Our primary goals were to support field experiments by screening strains of bacteria to find favorable transport characteristics among field isolates and to estimate collision efficiencies for those bacteria in typical Oyster site sediments. The data we obtained were disseminated to other members of the subprogram. For example, Tim Ginn of PNL incorporated our results into his field model; Aaron Mills used our work for comparison purposes; and John Wilson used our results to determine if there is a correlation between facies type and cell adhesion. Copies of all information were also sent to Mary DeFlaun of Envirogen for incorporation into the Sample Tables. In addition to the originally proposed work, we performed longer column studies, examining the effects of aluminum, iron, and water chemistry on bacterial transport, and beginning to understand the role of electrostatic interactions as determinants of biocolloid/collector affinity.
