Microcosms, constructed with aquifer samples from Eglin Air Force Base, Florida, were spiked with selected concentrations of these electron acceptors.
Data also show biodegradation of toluene under denitrifying and iron-reducing conditions.
In conclusion, BTEX biodegradation under all the listed anaerobic conditions does not occur steadily or uniformly for all the compounds. The data in this study suggests that iron-reducing conditions may also be favorable for the biodegradation of some BTEX compounds in addition to the already shown success with denitrifying conditions.
