Methanogenic microbes not always limited to methane

A study led by microbiologists at TU Dresden shows that methanogenic archaea do not always need to form methane to survive. It is possible to bypass methanogenesis with the seemingly simpler and more environmentally friendly ...

Wired for efficiency: How methanogenic microbes manage electrons

Methanogenic archaea use sophisticated enzyme systems to live in energy-limited anoxic environments. A key mechanism for saving energy is electron bifurcation, a reaction that 'splits' the energy of a pair of electrons, making ...

New key players in the methane cycle

Methane is not only a powerful greenhouse gas, but also a source of energy. Microorganisms therefore use it for their metabolism. They do so much more frequently and in more ways than was previously assumed, as revealed by ...

Biochar could benefit anaerobic digestion of animal manure

New research by Texas A&M AgriLife Research scientists shows biochar has potential to make anaerobic digestion of animal manure a more efficient method to rid farms of waste while producing methane for energy.

Microbes could survive thin air of Mars

Microbes that rank among the simplest and most ancient organisms on Earth could survive the extremely thin air of Mars, a new study finds.

Cutting methane emissions from cattle

Cattle have bad breath and commonly suffer from severe, chronic flatus generating large amounts of methane, which is a greenhouse gas and a driver of anthropogenic global warming. There is an obvious answer to this problem, ...
