Biodegradation of Volatile, Halogenated, Aliphatic Compounds

这是一个奖项，旨在为研究提供支持，以确定使用微生物生物降解土壤中挥发性卤化脂肪族有机污染物的创新概念的可行性。挥发性卤代脂肪族化合物是危险废物场所的主要污染物。三氯乙烯是这一类中最常见的化合物。这些化合物是持久性的，因此需要某种形式的补救或去除。目前的技术利用碳吸附，这意味着将危险化合物转移到另一种必须通过燃烧净化的介质中。这项研究的主题是微生物过程的效率，将与使用碳吸附和使用表现出这种降解土壤污染物能力的替代微生物菌株所实现的效率进行比较。导致这一阶段I奖的提案是为了响应NSF 88-8，小型企业创新研究而提交的。结果可能提供一种替代的和更有效的程序，在目标化合物已经放置或移动到的地点去污土壤。

This is an award to provide support for research to determine the feasibility of an innovative concept using microbes to biologically degrade volatile halogenated aliphatic organic contaminants of soil. Volatile halogenated aliphatic compounds are predominant contaminants at hazardous waste sites. Trichloroethylene is the most commonly occurring compound in this class. These compounds are persistent and therefore require some form of remediation or removal. Present technology utilizes carbon adsorption, which means transferring the hazardous compounds to another medium which must be decontaminated by combustion. The efficiency of the microbial process that is the subject of this research will be compared with that achieved by use of carbon adsorption and by use of alternative strains of microorganisms that have exhibited this ability to degrade soil contaminants. The proposal leading to this Phase I award was submitted in response to NSF 88-8, Small Business Innovation Research. Results may provide an alternative and more efficient procedure to decontaminate soil at sites where the target compounds have been placed or to which they have moved.
