Biology of methanogenic archaea

Our research program involves investigation of methane producing microorganisms.

Despite the fact that all known methanogens depend on methanogenesis for growth, there is considerable variability both in terms of energy substrates utilized and catabolic pathways employed.

Selenium metabolism in Archaea

Selenium (named after the greek goddess of the moon), which is an essential trace element in many organisms, is found in the catalytic site of numerous redox-active enzymes in the form of selenocysteine within all three domains of life.

Genetic methods for methanogens

Despite the past progress, genetic analysis of methanogens is generally still not a routine approach. Many powerful techniques, which are commonly applied for other organisms have not yet been adapted for genetic analysis of methanogens.

Biology of methanogenic archaea

Methane is the most abundant hydrocarbon present in our atmosphere. It represents either a highly attractive renewable energy source because aerobic combustion of methane produces only H₂O and CO₂, or a frightening contribution to global warming because the global warming potential of methane is more than 20 times higher than that of CO₂.
