  • Title: [Anaerobic biodegradation of tetrachloroethylene with methanol as co-metabolism substrate].
    Author: Li HD, Yang Q, Shang HT.
    Journal: Huan Jing Ke Xue; 2004 May; 25(3):84-8. PubMed ID: 15327260.
    Abstract:
    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. DCEs, VC and ethene are probably end products. It also shows that PCE, TCE degradation and TCE production fit in first order kinetics. Reaction rate constants for PCE and TCE were 0.8991 d(-1) and 0.068 d(-1) respectively. Half-live were 0.77 d and 10.19 d respectively. TCE production rate constant was 0.1333 d(-1). Rate constants show that PCE is degraded more rapidly than TCE. Production rate of TCE is higher than degradation rate of TCE, so TCE exists through the experiment.
