This study aims to test the hypotheses that H2 utilizing microorganisms are more concentrated on rock surfaces for more direct access to H2 and that increased H2 can stimulate their growth. We will compare the microbial compositions in the biomass obtained from the planktonic phase, and rock surfaces with and without H2 enrichment. Sequences obtained in this study will also be combined with our existing metagenomic sequences into a de novo co-assembly. PI Maggie Lau, Princeton University

本研究旨在验证两项假说：其一，利用氢气（H₂）的微生物会更富集于岩石表面，以获取更直接的氢气供应；其二，氢气浓度提升可促进此类微生物的生长。本研究将对比从浮游相、以及添加与未添加氢气富集环境的岩石表面获取的生物质中的微生物群落组成。本研究获得的序列数据还将与现有宏基因组序列相结合，开展从头联合组装（de novo co-assembly）。首席研究员玛吉·劳（Maggie Lau），普林斯顿大学（Princeton University）
