项目摘要

Non-Technical DescriptionMethane is a greenhouse gas that traps heat in the atmosphere which results in undesirable changes to the climate. The recent surge in methane emissions has invigorated interest of the scientific community to explore the contributions of living microorganisms to both the production and the breakdown of methane. To more deeply understand these processes, this Research Infrastructure Improvement Track-2 Focused EPSCoR Collaborations (RII Track-2 FEC) award will form a new collaborative consortium of three institutions (South Dakota School of Mines and Technology, Montana State University and University of Oklahoma) for an integrated research and education effort that will focus on organisms that metabolize methane in extreme environments. Sanford Underground Research Facility and Yellowstone National Park will be used as testbeds for extreme environments in deep biosphere and thermal systems, respectively. Further, this consortium will enable the use of previously unexplored and novel microorganisms from extreme environments for biological conversion of atmospheric methane into commercial products including liquid biofuels, biopolymers, and direct current electricity. The project will provide career guidance for twelve early career faculty as well as education, training, and workforce development opportunities for a diverse cohort of junior researchers and graduate, undergraduate, and Native American high school students. Exchange visits among the consortium partners and industry engagement in the project enriches the educational of the student participants. Technical DescriptionThe overarching goals of this project are to investigate methane cycling in deep and extreme environments and develop new biological routes for converting methane into value-added products. These goals will be accomplished through the following integrated objectives: (i) characterize extreme methane oxidizing microbial communities; (ii) investigate the metabolic activities of novel methanotrophs and their roles in methane flux; (iii) model critical interactions of select members of these communities; (iv) edit genomes of select methanotrophs for phenotypic improvement in methane uptake and oxidation; and (v) establish a consortium for sustained collaborations among university partners in South Dakota, Montana, and Oklahoma in the field of methane regulation in extreme environments. The research will include: analysis of methane flux among novel methanotrophs individually as well as in interacting microbial communities; molecular investigations in genome editing to overexpress methane related synthetic gene cassettes and protein profiling; computational biofilm modeling, in-silico characterization of active sites of regulatory proteins responsible for methane oxidation to determine underlying molecular mechanisms; and bioelectrochemical investigations to elucidate electrogenic activity of new, extremophilic, methanotrophs and evaluate their potential for controllable, catalytic methane oxidation. Activities related to conversion of methane into value-added products facilitates industry engagement and potential career opportunities for students in industries. The program includes mentoring of twelve junior faculty by senior faculty in advancing through their careers and guiding graduate students.

非技术性描述甲烷是一种温室气体，在大气中捕获热量，导致气候发生不希望的变化。最近甲烷排放量的激增引起了科学界对探索活微生物对甲烷产生和分解的贡献的兴趣。为了更深入地了解这些过程，这项研究基础设施改进第二轨道重点EPSCoR合作（RII Track-2 FEC）奖将组建一个由三个机构（南达科他州矿业与技术学院、蒙大拿州州立大学和俄克拉荷马大学）组成的新合作联盟。俄克拉荷马州）的综合研究和教育工作将重点关注在极端环境中代谢甲烷的生物体。桑福德地下研究设施和黄石国家公园将分别用作深层生物圈和热系统极端环境的试验台。此外，该财团将能够使用来自极端环境的以前未开发的和新的微生物，将大气甲烷生物转化为商业产品，包括液体生物燃料，生物聚合物和直流电。该项目将为12名早期职业教师提供职业指导，并为不同群体的初级研究人员以及研究生、本科生和美洲原住民高中生提供教育、培训和劳动力发展机会。联盟合作伙伴之间的互访和行业参与项目丰富了学生参与者的教育。技术描述该项目的总体目标是研究深海和极端环境中的甲烷循环，并开发将甲烷转化为增值产品的新生物路线。这些目标将通过以下综合目标来实现：（i）表征极端甲烷氧化微生物群落;（ii）研究新型甲烷氧化菌的代谢活动及其在甲烷通量中的作用;（iii）模拟这些群落的选定成员的关键相互作用;（iv）编辑选定甲烷氧化菌的基因组以改善甲烷吸收和氧化的表型;（iv）研究甲烷氧化菌的代谢活性及其在甲烷通量中的作用。以及（v）在南达科他州、蒙大拿州和俄克拉荷马州的大学伙伴之间建立一个联盟，在极端环境下的甲烷调节领域进行持续合作。研究将包括：分析新型甲烷氧化菌个体之间以及相互作用的微生物群落中的甲烷通量;基因组编辑中的分子研究，以过表达甲烷相关的合成基因盒和蛋白质谱;计算生物膜建模，负责甲烷氧化的调节蛋白的活性位点的计算机表征，以确定潜在的分子机制;和生物电化学调查，阐明新的，极端，甲烷氧化菌的产电活性，并评估其可控，催化甲烷氧化的潜力。与甲烷转化为增值产品有关的活动促进了行业参与和学生在行业中的潜在职业机会。该计划包括由高级教师在通过他们的职业生涯和指导研究生推进12初级教师的辅导。
