Research Initiation Award: Anaerobic Biotransformation of Environmental Pollutants by Microbial Co-Enzymes

9410363 Nies该奖项旨在为一个项目提供支持，该项目的总体目标是研究氯化有机化合物的还原脱氯和微生物辅酶介导的金属生物甲基化的相互作用。 研究人员计划在三个重叠的时期内完成这项工作，其中第一个时期将描述汞等金属在特定化学系统中发生甲基化的实验条件。 然后，他计划在类似定义的化学条件下，结合还原脱氯，研究金属的甲基化，然后确定这些过程单独发生和在厌氧沉积物中结合的速率。 含有污染物混合物的空气、水、土壤、沉积物和淤泥的净化，其中每一种都需要不同的去除或转化程序，这在旨在恢复受污染介质的有用质量的工艺和系统的工程设计中构成了一个特殊的问题。 研究结果将为重金属和氯代有机化合物混合物污染环境介质的净化过程的工程设计提供指导。 导致这个奖项的建议是在雅阁与NSF 92-122，研究启动奖励计划提交。 ***

9410363 Nies This is an award to provide support for a project, the overall objective of which is to study interactions of reductive dechlorination of chlorinated organic compounds and the biomethylation of metals mediated by microbial coenzymes. The investigator plans on doing this in three overlapping periods, the initial one of which will characterize the experimental conditions under which methylation of metals like mercury occurs in a defined chemical system. He then plans on examining the methylation of metals when combined with reductive dechlorination under similarly defined chemical conditions followed by determination of the rates at which these processes occur individually and combined in anaerobic sediments. The decontamination of air, water, soil, sediments and sludges containing mixtures of pollutants, each of which requires a different removal or transformation procedure, poses a special problem in the engineering design of processes and systems that are aimed at restoration of the useful qualities of the contaminated media. Results will provide guidance for engineering design of processes to decontaminate environmental media contaminated by mixtures of heavy metals and chlorinated organic compounds. The proposal leading to this award was submitted in accord with NSF 92-122, Research Initiation Awards Program. ***
