Research interests

Windmills and photovoltaics are renewable energies largely implemented which eventually lead to an excess of electricity, and its storage is essential, and that is where the power-to-gas (P2G) approach begins. Such excess electricity can be used to generate hydrogen throughout water electrolysis, and that hydrogen, if injected in biogas plants (another renewable energy generating bioprocess from organics) helps to upgrade the methane content of the raw biogas. The bioprocess is named biomethanation and is mediated by hydrogenotrophic methanogens.

In this project, I am investigating different reactor microbiomes as well as pure cultures to perform biomethanation. Operational parameters, pH tolerance, functional redundancy and competing pathways (homoacetogenesis) in the microbiome will be explored. Different process parameters, molecular methods (mcrA T-RFLP, 16s-rRNA Amplicon Sequencing), omics (metagenomics and metatranscriptomics), and bioinformatics, as well as stable isotope techniques, will be used to investigate the bioprocess.
