title: Degradation of p-xylene by a denitrifying enrichment culture.
abstract: Microbial cultures enriched from a diesel fuel-contaminated aquifer were able to grow on p-xylene under denitrifying conditions. The oxidation of p-xylene to CO2 was coupled to the reduction of NO3-. The enrichment cultures also grew on toluene and m-xylene, but they did not degrade benzene, ethylbenzene, and o-xylene.
