Abstract

Our work has focused on the determination of physiological traits that may facilitate in situ degradation of xenobiotic compounds by indigenous microorganisms. For this our interests center on the following questions: What are the ambient conditions in a benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated aquifer? What is the behavior of indigenous bacteria under these conditions? What are the attributes of bacterial strains that are functional under hypoxic conditions? How do these strains compare with other BTEX-degrading strains?
