In situ bioremediation of pentachlorophenol-contaminated ground water in a sequential
anaerobic-aerobic down borehole permeable barrier reactor requires a non-toxic primary
substrate for dichlorophenol cometabolism. Serum bottle tests comparing the
effectiveness of eight primary substrates for aerobic dichlorophenol degradation showed
phenol to be the most effective followed by imitation vanilla flavoring, guaiacol, sodium
benzoate, molasses, acetic acid, propylene glycol and ethyl vanillin in propylene glycol.
As phenol is a pollutant, imitation vanilla flavoring is the recommended primary substrate
for field use. In a second bottle test, 3,4,5-trichlorophenol was not sufficiently
biotransformed, emphasizing the need for biotransformation to occur in the anaerobic
zone of the reactor. / Graduation date: 1996
