Abstract/OtherAbstract:
Microbial ecology provides the link between basic biochemical and molecular studies on toxicity reduction by microbial metabolism and environmental studies that determine exposure. This link provides the ability to determine which microorganisms are responsible for the actual transformations in nature, thereby establishing how predictive the laboratory pathway, kinetic, regulatory, and enzyme mechanistic information is for nature. This information can be important to the rate of toxicant removal, the type and concentration of intermediate product(s), and the identification of conditions that limit effective toxicant removal. Nucleic acid-based methods now provide the main means to track important biodegrading populations. Examples of these methods are given that illustrate tracking a biodegrading microbe injected into an aquifer, following community succession in a toluene-degrading fluidized bed reactor, aiding the isolation from nature of novel biodegrading organisms, and rapidly characterizing the extent of microbial diversity in an aquifer stimulated to co-metabolize trichloroethene.
