Co-Metabolic Inhibition Kinetics of Chlorinated Hydrocarbon Degradation by Methane- and Propane Oxidizers

这一奖项旨在为氯代烃的生物降解研究提供支持，这些研究对水污染具有重要意义。正在研究的特定化合物是1，1，1-三氯乙烷、三氯乙烯和氯乙烯。以前的工作表明，这些化合物可以被甲烷和丙烷氧化细菌好氧降解，但忽略了生长底物和氯代烃对降解速度的竞争影响。在这项工作中，将确定甲烷和丙烷水平对目标化合物降解率的影响，并将结果应用于这些化合物的序批式降解模型反应器的开发。本研究的预期结果是建立一个可用于含氯代烃废物生物反应器工程设计的数学模型。这项研究的成功完成将为设计高速率、好氧生物系统以销毁具有重大污染意义的氯代烃提供必要的信息。

This is an award to provide support for research on the biological degradation of chlorinated hydrocarbons that are of significance with respect to contamination of water. The specific compounds being investigated are 1, 1, 1-trichloroethane, trichloroethylene, and vinyl chloride. Previous work has shown that these compounds can be degraded aerobically by methane and propane oxidizing bacteria but has neglected the competitive effects of the growth substrate and the chlorinated hydrocarbons on the rate of degradation. In this work, the effects of methane and propane levels on the degradation rate of the target compounds will be determined and the results applied to developments of model sequencing batch reactors for degradation of those compounds. A mathematical model that can be utilized in the engineering design of bioreactors for treatement of wastes containing chlorinated hydrocarbons is the expected result of this research. Successful completion of this research will provide information that is essential for design of high-rate, aerobic biological systems for destruction of chlorinated hydrocarbons of pollutional significance.
