Trace metals in biogas production processes

Performance of anaerobic digestion processes depend on a balanced supply of trace metals, which are required for the activity of the enzymes driving the metabolic machinery of the anaerobic microorganisms. We study the processes which control the chemical speciation and bio-uptake of trace metals in biogas reactors.


Molecular level characteristics of organic matter in biogas reactors

The nature of organic compounds in anaerobic digestion processes determines the degree of the organic matter conversion to biogas. We study molecular-level characteristics of underutilized organic matter in biogas reactors to further improve their degradability and thus, the biogas production efficiency
