A metagenomic study of the microbial communities in four parallel biogas reactors

-This study showed that four parallel reactors co-digesting manure and fish waste silage operated stably during a startup phase. Several important Archaea and Bacteria degrading the protein-rich substrate were identified. In particular, microorganisms involved in syntrophic methane production seemed to be important. The detailed characterization of the microbial communities presented in this work may be useful for the operation of biogas plants degrading substrates with high concentrations of proteins

Metagenomics in CO2 Monitoring

-Leakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying the Johansen formation, a potential site for CO2 storage, using metagenomics. We detected six abundant potentially CO2 fixing strains (e.g. Nitrosopumilus maritimus SCM1) as well as key genes for CO2 fixation pathways (e.g. the reductive tricarboxylic acid cycle and the Wood Ljungdahl pathway). Assuming this fraction of the community would increase in case of CO2 leakage; this information could be used as part of a surveillance project
