Biomineralisationsprozesse, Biogeochemie und Biodiversität chemolithotropher Mikroorganismen im Tunnel von Äspö (Schweden)

研究了Äspö硬岩实验室（Äspö隧道）不同深度的微生物，作为深部大陆生物圈生物多样性和结构的模型系统，以及微生物过程与矿物降水的相互作用。主要研究方向包括：(1)微生物系统的生物多样性，包括宏基因组学；(2)代谢途径和生物矿化过程，包括eps控制的选择性阳离子结合和复合物的形成；(3)涉及深层生物圈微生物的生物地球化学过程的无机和有机生物特征。后一个主题将强调小型环境样品分析的小型化技术（特别是GC/MS， ToF-SIMS， raman光谱），以及化石深层生物圈生物标志物代理的建立。

Microorganisms occurring at different depths in the Äspö Hard Rock laboratory (tunnel of Äspö) are studied as model systems for the biodiversity and structure of the deep continental biosphere, and the interaction of microbiological processes and mineral precipitation.Major aspects investigated are (1) the biodiversity of microbial systems including metagenomics, (2) metabolic pathways and biomineralization processes, including EPS-controlled selective cation binding and complex formation, (3) inorganic and organic biosignatures for biogeochemical processes involving deep biosphere microorganisms. The latter topic will emphasize miniaturized techniques for analysing small environmental samples (particularly GC/MS, ToF-SIMS, RAMAN-spectroscopy), and the establishment of biomarker proxies for a fossil deep biosphere.
