Tianyu Zhang from Department of Mathematical Sciences, will present a seminar, "Modeling the biogeochemistry of sulfate reducing biofilms in pipeline corrosion," on Thursday, November 29, 2012 03:10 PM to 04:00 in EPS 126 or 127.Sulfate-reducing bacteria (SRB) are those bacteria and archaea that can obtain energy by oxidizing organic compounds or molecular hydrogen H_2 while reducing sulfate SO^2-_4 to hydrogen sulfide H_2S . SRBs have both good impacts such as maintaining the surfur cycle on earth, cleaning up contaminated soils and bad impacts such as causing corrosion of metal and concrete structures. We develop a mathematical model describing the biogeochemistry of sulfate reducing biofilms in pipeline corrosion. The model incorporates the essential chemical and biological processes involved as well as the growth and detachment of the biofilm. Numerical results and sensitivity analysis of model parameters are also provided.
