Use of a Novel Electron Acceptor for Stimulating Bioremediation

该奖项旨在支持对氯酸钠作为电子受体在微生物代谢过程中的潜在利用的研究，这些微生物能够利用土壤和含水层的有机污染物作为呼吸碳的来源。获得该奖项的提案是在NSF 89-85探索性研究小额赠款（SGER）中概述的条件下提交的。研究人员计划探索使用氯酸钠来允许白腐真菌继续呼吸，在气/液界面形成真菌垫后，抑制或阻止大气中的氧气进入含有污染物的流体。白腐真菌以其降解具有污染意义的芳香烃的能力而闻名。预计该项目的结果将为进一步探索在阻止或抑制大气源氧气使用的条件下氯酸钠作为呼吸氧来源的潜在用途提供基础。在这方面的成功很可能导致将这一概念应用于净化被生物可降解有机物质污染的土壤和地下水含水层。

9414423 Logan This is an award to support research on the potential utilization of sodium chlorate as an electron acceptor for metabolic processes in microorganisms that are capable of utilizing organic contaminants of soil and aquifers as a source of respiratory carbon. The proposal leading to this award was submitted under conditions outlined in NSF 89-85, Small Grants for Exploratory Research (SGER). The investigator plans on exploring the use of sodium chlorate to permit white rot fungi, known for their capability of degrading aromatic hydrocarbons of pollutional significance, to continue respiring after the formation of a fungal mat at the gas/liquid interface inhibits or prevents the entry of atmospheric oxygen into the fluid containing the contaminants. Results of this project are expected to provide the basis for further exploration of the potential use of sodium chlorate as a source of respiratory oxygen under conditions that prevent or inhibit use of oxygen from atmospheric sources. Success in that respect is likely to result in application of this concept to decontamination of soil and groundwater aquifers contaminated by biodegradable organic substances.
