Description
Summary:Biodegradation studies and physicochemical characterizations remain important to the overall assessment of hazardous wastes. Wilber and Wang (1997) investigated the effects of three electron acceptors (oxygen, nitrate, and sulfate) and two supplemental carbon sources (acetate and glucose) on the biodegradation of alachlor and propachlor. Both herbicides biodegraded in the presence of both carbon sources and with each of the three electron acceptors; however, their most rapid transformation occurred under sulfate-reducing conditions. Kao and Borden (1997) used laboratory microcosms to evaluate benzene, toluene, ethylbenzene, and xylene (BTEX) biodegradation under nitrifying conditions. In general, minimal benzene degradation was found under denitrifying conditions. Bradley et al. (1997) investigated the potential for intrinsic bioremediation of 2,4-dinitrotoluene (DNT) by indigenous microorganisms from a shallow aquifer below an explosives-contaminated site. They found that 28% of the DNT was mineralized within 28 days and another 28% was transformed to reduced aminonitrotoluene products.
