CAREER:Quantification of Horizontal Gene Transfer as Adaptive Response to Containment Stress in Subsurface Microbial Communities-Development of an Experiential Environ. Eng. Course

9702361 Smets该奖项旨在为适当利用自然衰减来开发基于生物的技术的研究提供支持，以从被这些物质污染的土壤中去除有害物质。该研究基于一个假设，即水平传播遗传物质的交换和重排是土壤中现有微生物群落短期适应的主要因素，并且在压力存在下转移过程的表征可以提供可应用于土壤净化系统的工程设计的见解。这个奖项也为这位研究者作为教育者的早期发展提供了支持。他的教育计划涉及解决工程专业对工程师的需求，这些工程师将重要的技术知识基础与综合和跨学科整合能力结合起来。该奖项的提案是根据NSF 96-115“教师早期职业发展（Career）计划”提交的。微生物群落如何适应污染压力的定量知识有助于系统和程序的工程设计，以利用自然发生的生物群落的能力，从土壤和受污染的含水层中去除污染物。＊＊＊

9702361 Smets This is an award to provide support for research on appropriate use of natural attenuation to develop biologically-based technologies for removal of hazardous substances from soil that is contaminated with these substances. The research is based on a hypothesis that the exchange and rearrangement of horizontally transmissible genetic material is a major contributor to the short-term adaptation of existing microbial communities in soil and that characterization of the transfer process in the presence of stress can provide insights that can be applied to engineering design of systems for decontamination of soil. This award also provides support for the continuation of this investigator's early development as an educator. His education plan involves addressing the engineering profession's demands for engineers who couple a significant technical base of knowledge with an ability for synthesis and cross-disciplinary integration. The proposal leading to this award was submitted in response to NSF 96-115, "Faculty Early Career Development (CAREER) Program." Quantitative knowledge of how microbial communities adapt to contaminant stress can assist in the engineering design of systems and procedures to exploit the capability of naturally occurring communities of organisms to removal of contaminants from soil and contaminated aquifers. ***
