Biodegradation of tetrachlorothylene using methanol as co-metabolic substrate.

Objective: To investigate the biodegradation of tetrachloroethylene (PCE) using methanol as electron donor by acclimated anaerobic sludge.

Methods: HP-6890 gas chromatograph (GC), together with HP-7694 autosampler, was used to analyze the concentration of PCE and intermediates.

Results: PCE could be decholrinated reductively to DCE via TCE, and probably further to VC and ethylene.

Anaerobic degradation of tetrachloroethylene using different co-substrates as electron donors.

Objective: To investigate the biodegradation of tetrachloroethylene (PCE) by acclimated anaerobic sludge using different co-substrates, i.e., glucose, acetate, and lactate as electron donors.

[Anaerobic biodegradation of tetrachloroethylene with methanol as co-metabolism substrate].

Tetrachloroethylene (PCE) is biodegraded by reductive dechlorination in anaerobic condition. PCE degradation by methanol as co-metabolism substrate was studied. Results show that PCE was dechlorinated reductively to DCEs and TCE, probable VC and ethene.
