Biological Methane Conversion

2023
Methanotrophs are microorganisms capable of growing on methane as their sole carbon source. Many scientists from academia and industry have proposed that these microorganisms can upgrade methane into value-added chemicals. Biological processes utilizing these microorganisms may provide a more economical alternative to existing thermo-chemical gas-to ...

Biological hydrogen methanation – A review

Bioresource Technology, 2017
Surplus energy out of fluctuating energy sources like wind and solar energy is strongly increasing. Biological hydrogen (H2) methanation (BHM) is a highly promising approach to move the type of energy from electricity to natural gas via electrolysis and the subsequent step of the Sabatier-reaction.

Biological conversion of methane to methanol

Korean Journal of Chemical Engineering, 2013
The conversion of methane to methanol is important to economic utilization of natural/shale gas. Methanol is a valuable liquid fuel and raw material for various synthetic hydrocarbon products. Its industrial production is currently based on a two-step process that is energy-intensive and environmentally unfriendly, requiring high pressure and ...

The physiology of trace elements in biological methane production

Bioresource Technology, 2017
Trace element (TE) requirements of Methanothermobacter okinawensis and Methanothermobacter marburgensis were examined in silico, and using closed batch and fed-batch cultivation experiments. In silico analysis revealed genomic differences among the transport systems and enzymes related to the archaeal Wood-Ljungdahl pathway of these two methanogens. M.

Biologically Produced Methane as a Renewable Energy Source

2016
Methanogens are a unique group of strictly anaerobic archaea that are more metabolically diverse than previously thought. Traditionally, it was thought that methanogens could only generate methane by coupling the oxidation of products formed by fermentative bacteria with the reduction of CO2. However, it has recently been observed that many methanogens

Direct Biological Conversion of Electrical Current into Methane by Electromethanogenesis

Environmental Science & Technology, 2009
New sustainable methods are needed to produce renewable energy carriers that can be stored and used for transportation, heating, or chemical production. Here we demonstrate that methane can directly be produced using a biocathode containing methanogens in electrochemical systems (abiotic anode) or microbial electrolysis cells (MECs; biotic anode) by a ...
