Greenhouse gases

microbes, pathways and environmental controls

Microbes play key roles in the production and consumption of the climate-relevant greenhouse gases methane and nitrous oxide. However, large open questions remain about the pathways involved and how these are controlled by microbial interactions. At Nordcee, we combine biogeochemical, microbiological and biomolecular approaches to unravel the mechanisms of methane and nitrous oxide cycling in aquatic systems. This work is critical to allow predictive modeling of how methane and nitrous oxide emissions will respond to global change. The investigations complement those on CO2 and the carbon cycle described in Sustainability and biotechnology and Microbes as drivers of global element cycles.
