Enhancing Production of Biosurfactants for Xenobiotic Re- mediation

这是一个奖项，以支持研究的概念， 去除土壤中的有机污染物 具有天然攻击有机物能力的微生物 吸附在土壤颗粒上的化合物， 生物降解是否可以通过 表面活性剂的存在。 调查员计划 建立一个定义的模型系统， 萘饱和土壤和一种已知的 有效地降解这种化合物。 然后他计划 评价合成表面活性剂对其 降解这种化合物的能力，并确定是否 已知产生表面活性剂的细菌可用于 合成表面活性剂的位置来实现相同的目的 最终结果更加高效和有效。 该提案是为了响应计划而提交的。 公告NSF 88-99，研究启动奖。 研究结果可为工程设计提供参考 基于生物的补救措施，可能与 用于去除污染物的化学和/或物理系统 可能是地下水的污染物。

This is an award to support research on a concept for removing organic contaminants from soil using microorganisms with natural ability to attack the organic compounds adsorbed on soil particles and to determine whether biological degradation could be enhanced by presence of surfactants. The investigator plans on establishing a defined model system consisting of a naphthalene saturated soil and an organism known to efficiently degrade this compound. He then plans to evaluate the effects of synthetic surfactants on their ability to degrade this compound and to determine whether bacteria known to produce surfactants could be utilized in place of the synthetic surfactants to accomplish the same end result more efficiently and effectively. This proposal was submitted in response to Program Announcement NSF 88-99, Research Initiation Awards. Results are expected to improve the engineering design of biologically-based remediation, potentially coupled to chemical and/or physical systems for removing contaminants from soil that are likely contaminants of groundwater.
