Project description:Background: Biological conversion of the surplus of renewable electricity to CH4 could support energy storage and strengthen the power grid. Biological methanation (BM) is closely linked to the activity of biogas-producing bacterial community and methanogenic Archaea in particular. During reactor operations, the microbiome is often subject to various changes whereby the microorganisms are challenged to adapt to the new conditions. In this study, a hydrogenotrophic-adapted microbial community in a laboratory-scale BM fermenter was monitored for its pH, gas production, conversion yields and composition. To investigate the robustness of BM regarding power oscillations, the biogas microbiome was exposed to five H2 starvations patterns for several hours.
Project description:In this work we used metaproteomics to study the effect of pH and nitrogen source on cyanobacterial growth of the laboratory cultures. The database for protein identification was obtained from assembled metagenomes.
Project description:Metaproteome of cyanobacterial crusts exposed to stratosphere. To explore changes in community structure and function. The changes in function involve overall metabolic response, interactions between species and function, and content related to life history strategies. The article mainly focuses on metagenomic and metatranscriptome data, while metaproteomic data is mainly used to assist in confirming the conclusions drawn.
