This Partnership for Innovation project from the University of Minnesota-Twin Cities will take a successful bioremediation technology previously used for pesticide removal from water and re-engineer it for use in microbiologically-enhanced coal-bed natural gas recovery from depleted gas wells and in bioremediation of the percentage of water returned via the well from waters generated during the hydraulic fracturing (fracking) method of drilling for shale oil, oil sands, and gas. The technology is based on encapsulating microorganisms in an inexpensive, safe, extended life-time, silica-based hybrid gel. The microbes are stabilized within the gel and continue to biodegrade pesticides for more than four months. In re-engineering the platform technology for enhanced recovery, communities of microorganisms that transform coal to natural gas will be stabilized by silica encapsulation for ease of transport, enhanced stability, and improvement of function. In re-engineering of the platform technology for bioremediation, microbes will be stabilized and rendered highly active to biodegrade organic contaminants within the percentage of water returned via the well from waters generated during the hydraulic fracturing (fracking) method of drilling. The broader impacts of this research are on possible future applications to an efficient and safe oil and gas industry. There is a strong link between a robust domestic energy sector and the creation of new jobs. The U.S. has recently become a net exporter of energy, credited largely to advances in shale oil and gas extraction that use hydraulic fracturing. This proposal develops technologies to enhance gas and oil recovery and a platform that can minimize the environmental impacts from a percentage of the water that is returned via the well and then kept in settling ponds. Two of the knowledge enhancement partners (KEPs) will take away technology to develop and scale-up production of silica-encapsulated, biodegrading bacteria that can be used for treating fracking water in settling ponds. Biostabilization imparted by the silica materials is also important for preserving microbial communities that transform coal to natural gas. One of the KEPs will take away this technology to enhance the ability to deliver microorganisms that increase natural gas production throughout the U.S. and potentially in foreign markets. This application is important because the U.S. has enormous coal reserves and enhancing coal to methane conversion will contribute to a clean energy future for our country.Partners at the inception of the project: the lead instituion, University of Minnesota-Twin Cities (Department of Biochemistry; Bioresource Center, Biotechnology Institute; Sponsored Projects Administration; Office of Technology Commercialization; Venture Center; and Office of the General Counsel; KEP core small businesses: 1) Luca Technologies (Boulder, CO) 3F LLC (St. Paul, MN) and 3) Tundra Companies (White Bear Lake, MN).

明尼苏达大学汤威大学（University of Minnesota-Twin）城市的这项创新合作伙伴关系将采用以前用于从水中清除农药的生物修复技术，并重新工程师用于微生物学的天然气中燃煤天然气从耗尽的天然气井中从耗尽的天然气孔中恢复，并在耗尽的水中返回的水上生成的水平（在水上生成的水平）（在水上生成的水平）（在水上生成）（在水上生成）（在水上生成的弗里克（Frieling for）（在水上生成的水）（在水上生成的水平）（在水中返回的水平（在水）中，该方法（在水上生成的弗里克（Frieling of Frient）（在水上生成的水平）（在水上生成的水平）（油，油砂和气体。该技术基于在廉价，安全，延长的终身，基于二氧化硅的混合凝胶中封装微生物。微生物在凝胶中稳定，并继续生物降解农药超过四个月。为了重新设计以增强恢复的平台技术，将煤炭转化为天然气的微生物群落将通过二氧化硅封装来稳定，以易于运输，增强的稳定性和功能改善。在重新设计生物修复的平台技术时，微生物将稳定下来，并在液压压裂（压裂）钻井方法中通过水的水的百分比进行生物降解的有机污染物。这项研究的更广泛影响是对有效且安全的石油和天然气行业的未来应用。强大的国内能源部门与新工作的创造之间存在牢固的联系。美国最近已成为能源的净出口国，主要归功于使用液压压裂的页岩油和天然气提取的进步。该提案开发了增强天然气和石油回收的技术，以及一个可以将通过井返回的水的百分比，然后保持沉降池塘所产生的环境影响的平台。两个知识增强伙伴（KEP）将带走技术，以开发和扩展二氧化硅已封装的生物降解细菌，可用于在沉降池塘中处理压裂水。二氧化硅材料赋予的生物稳定化对于保存将煤炭转化为天然气的微生物群落也很重要。其中一位KEP将带走这项技术，以增强提供微生物的能力，从而增加美国各地的天然气产量以及在国外市场中的可能性。 This application is important because the U.S. has enormous coal reserves and enhancing coal to methane conversion will contribute to a clean energy future for our country.Partners at the inception of the project: the lead instituion, University of Minnesota-Twin Cities (Department of Biochemistry; Bioresource Center, Biotechnology Institute; Sponsored Projects Administration; Office of Technology Commercialization; Venture Center; and Office of the General Counsel; KEP core small企业：1）Luca Technologies（Boulder，CO）3F LLC（明尼苏达州圣保罗）和3）苔原公司（明尼苏达州白熊湖）。
