Abstract
An assay method for screening microorganism-containing compositions for degradation capacity via the 2,3-dioxygenase pathway includes a first step of contacting the microorganism with a polychlorinated aromatic compound which is not susceptible to such degradation but which, when anaerobically dechlorinated, affords products which are susceptible to such degradation. The resulting product is contacted in a second step with an indicator microorganism encoding the first three steps but not the fourth step of the 2,3-dioxygenase route, and the presence of color in the resulting product is an indication that dechlorination took place in the first step. The presence in a test sample of halogenated aromatic compounds capable of degradation by the 2,3-dioxidase pathway can be determined by employing the second step alone.
