the process of methanogenesis in a coal mine
Coal Methanogenesis | Biodesign Institute | ASU
Coal methanogenesis: energy production and water management. Planning for the future energy requirements requires innovative, multi-faceted, short-term and long-term approaches. Clearly, the long-term goal is to move away from fossil fuels and carbon-based energy, however mid-term or short-term alternatives are required to bridge current energy ...

Microbial methanogenesis in subsurface oil and coal ...
Methanogenesis and methanogenic archaea. Biogenic methane production, or methanogenesis, is the terminal electron-accepting step of all respiratory chains in organic-rich, anoxic, electron acceptor-poor environments (Schink, 1997). Despite this wide distribution, methanogenesis is restricted to a very limited range of organic substrates.

Methanogenesis - an overview | ScienceDirect Topics
Methanogenesis is the dominating terminal OM degradation process in anoxic freshwater environment. Methanogenesis has been reported to account for 20–56% of the total carbon mineralization in lakes (Table 6). CH 4 oxidation can be comparable to primary production, and has the potential to rapidly consume large amounts of O 2.

Methanogenesis - Current Biology
2018-7-9 · Methanogenesis is an anaerobic respiration that generates methane as the final product of metabolism. In aerobic respiration, organic matter such as glucose is oxidized to CO 2, and O 2 is reduced to H 2 O. In contrast, during hydrogenotrophic methanogenesis, H 2 is oxidized to H +, and CO 2 is reduced to CH 4.Although similar in principle to other types of
