Isolation of selected organisms from methanogenic communities
Abstract
With the European Green Deal, energy system transformation was recently declared a key priority of European policy. However, in order to meet the goal of climate neutrality by 2050, resilient energy storage technologies must be made available in addition to the expansion of renewable forms of energy: For this purpose, a special power-to-gas process, geomethanisation, enables the conversion of electricity into methane gas. This conversion is carried out by methanogenic, microbial communities in depleted natural gas deposits, which feed on electrolytic hydrogen and carbon dioxide. The structure of the microbial consortium and interactions between species are likely to be crucial to the overall process. The aim of this research project is the isolation of unknown anaerobic organisms from reservoir formation water of a porous natural gas storage to investigate ecological implications. After an initial molecular genetic characterisation of the microbial community, selective enrichment cultures are to be produced using methods of anaerobic microbiology. After successful isolation, the genome will be elucidated and published. The knowledge gained in this process should lead to an improved understanding of the geomethanisation process and also shed light on unresolved questions of the microbial ecology of methanogens and their partners.
