Nature's helpers: Using microorganisms to remove TCE from water

Bruce Rittmann's Biodesign Institute research team has utilized a system, called the microbial biofilm reactor, that uses a naturally occurring group of microorganisms to remove TCE from water. Here, ASU assistant professor Rosa Krajmalnik-Brown and graduate research assistant Michal Ziv-El assemble a membrane biofilm reactor to test against TCE.
