项目摘要

This research is novel in that its creates a first-of-a-kind model that accounts for the effects of fluid transport and microbial metabolic processes in fluid mixing environments at seafloor hydrothermal vent systems. Hydrothermal vents are some of the most interesting and important extreme environments on the planet and the microbes that inhabit them are potential targets for new compounds for natural products studies from which new and important pharmaceuticals might be derived. This project links together for the first time, the chemosynthetic hydrothermal vent biological communities and the geologic/geochemical processes taking place in the subsurface. The resulting mathematical and computational models portray chemical environments that account for the impact of microbial metabolism on evolving fluid chemistry during the mixing of seawater and hydrothermal fluid and could be used to direct bioprospecting. Models will be constrained by reported compositions of high-temperature, focused and low-temperature diffusively venting fluids as well as microbial distribution in seafloor hydrothermal environments collected during the RIDGE 2000 program. The broader impacts of the work include creating modeling codes for reactive transport modeling which explicitly include reactions mitigated by microbes, student training, and the development of a workshop on modeling bioenergetic reactions.
这项研究是新颖的,因为它创建了一个第一种模型,该模型解释了海底热液喷口系统流体混合环境中流体输送和微生物代谢过程的影响。热液喷口是地球上最有趣和最重要的极端环境之一,栖息在其中的微生物是天然产物研究新化合物的潜在目标,从中可能衍生出新的重要药物。该项目首次将化学合成热液喷口生物群落与地下发生的地质/地球化学过程联系在一起。由此产生的数学和计算模型描绘的化学环境,占不断变化的流体化学在海水和热液流体的混合过程中微生物代谢的影响,并可用于指导生物勘探。模型将受到所报告的高温、集中和低温扩散性排放流体的组成以及在脊2000方案期间收集的海底热液环境中的微生物分布的限制。这项工作的更广泛的影响包括创建反应性运输建模的建模代码,其中明确包括微生物减轻的反应,学生培训,以及建立生物能反应建模研讨会。
