Biodegradation of Volatile, Halogenated, Aliphatic Compounds

这是一项奖励，以支持根据美国国家科学基金会第88-60919号拨款启动的一个项目的第二阶段，该项目符合国家科学基金会88-8号《小型企业创新研究计划征集》中概述的条件。第一阶段的工作证明了利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。该工艺对三氯乙烯的破坏率高达99.9%。在第二阶段，工作范围将缩小到规模足够大的液态反应器，以促进原型生物反应器的全面设计和建造，并通过确定其效率和经济可行性来确定该工艺的商业适用性。这项研究的目标是有机化合物对地下水和地表水的污染，这是一个国家高度关注的问题。当务之急是开发能够更有效地应对土壤去污的技术。1预计该项目的成果将在这方面发挥作用。

This is an award to support for Phase II of a project initiated under NSF Grant No. 88-60919 under conditions outlined in the Program Solicitation for Small Business Innovation Research, NSF 88-8. The work under Phase I resulted in demonstration of the feasibility of an innovative concept using microbes to biologically degrade volatile halogenated aliphatic organic contaminants of soil. The process achieved as much as 99.9 percent destruction of trichloroethylene. In Phase II, the scope of the work will be narrowed to a liquid-phase reactor that is of sufficiently large scale to facilitate full- scale design and construction of prototype bioreactors and determine the commercial applicability of the process by determining its efficiency and economic feasibility. The contamination of ground and surface waters by organic compounds that are the target of this research is a matter of great National concern. It is imperative that technologies be developed that are more efficiently responsive to decontamination of soil.1 Results of this project are expected to be useful in this respect.
