This Growing Convergence Research project will test the overarching hypotheses that exceptional preservation of organic material was influenced, in part, by microbially mediated, rapid deposition of carbonate minerals in response to elevated atmospheric pCO2, and that the mechanisms by which these microbes sequestered atmospheric CO2 as carbonate minerals can be discerned and harnessed to mitigate rising atmospheric concentrations of this greenhouse gas. To effectively study these hypotheses, a research team spanning microbiology, proteomics, paleoimmunology, sedimentology/geochemistry, paleontology, and engineering was assembled. The results of this project will enhance understanding of: (i) mechanisms of exceptional preservation and their potential application, (ii) the relationship between CO2 levels and microbial evolution, (iii) characterization of environments under greenhouse/high-pCO2 conditions, and iv) microbial participation in carbon sequestration. Microbial mechanisms investigated within this proposed work may provide a route for the development of economical and scalable methods to sequester CO2.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个不断增长的收集研究项目将测试总体假设，即有机材料的特殊保存受到微生物介导的，碳酸盐矿物质的快速沉积，响应于大气中的升高，而这些机制响应于这些微生物序列的碳酸盐二氧化碳作为碳酸盐矿物质可以分辨出这种机制，从而使碳酸盐矿物质具有浓度和浓度为中心。为了有效地研究这些假设，组装了一个涵盖微生物学，蛋白质组学，古免疫学，沉积学/地球化学，古生物学和工程学的研究团队。该项目的结果将增强对：（i）特殊保存及其潜在应用机制，（ii）二氧化碳水平与微生物进化之间的关系，（iii）在温室/高PCO2条件下对环境的表征以及IV）微生物参与碳序列。 在这项拟议的工作中研究的微生物机制可能为开发经济和可扩展方法的开发提供了隔离CO2的途径。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估审查标准来通过评估来获得支持的。
