This SBIR Phase I project will develop a robust commercial acid-tolerant culture of the anaerobic bacterium Dehalococcoides (Dhc) for in-situ treatment of groundwater contaminated with tetrachloroethene (PCE) and trichloroethene (TCE). The project team will conduct a search of acidic contaminated sites for natural Dhc strains having acid tolerance. The most promising strains will be combined to create a commercial dechlorinating culture.The broader/commercial impact of the proposed project will be the deployment of a bioremediation solution to address and solve many existing acid-caused remediation failures and thereby increase the effectiveness of existing in-situ biological treatment techniques as a cost-effective and successful remedial option to eliminate PCE and TCE from groundwater.

该SBIR I期项目将开发出厌氧细菌脱核苷（DHC）的强大的耐酸性耐酸培养物，用于对被四氯乙烯（PCE）和三氯乙烯（TCE）污染的地下水进行原位处理。 项目团队将对具有酸耐受性的天然DHC菌株进行搜索。 最有希望的应变将结合起来，以创造商业化的脱氯文化。拟议项目的更广泛/商业影响将是部署生物修复解决方案，以解决和解决许多现有酸引起的补救失败，从而提高现有的现有生物学治疗技术的有效性，以使其作为成本效益和成功的Repedial repedial repedeal andike Repedeal and tece roqualder requeDeatial socked pce and tce。
