Coal methanogenesis: a review of the need of

Microbial biodegradation of coal into low-molecular-weight compounds such as methane has been extensively researched in the last two decades because of the underlying environmental and industrial applications of this technique as compared to the chemical and physical methods of coal conversions. However, the irregular structure of coal and the need for complex microbial consortia under ...

Coal methanogenesis: a review of the need of

Coal represents more than 70% of all fossil fuels on this planet, while petroleum and natural gas represent only 17 and 2%, respectively (Sekhohola et al. 2013).However, this excessive and non-renewable source of energy should not be used abundantly due to the underlying environmental problems such as the emission of greenhouse gases and the resultant inorganic and residual

Stimulation of methanogenesis in bituminous coal

2020-11-1  Methanogenesis in coal samples after stimulation by consortia SZ A and PT A was higher than had been previously observed e.g. in coal samples from the Deer Creek Coal Mine (Utah, USA), where similar inoculate sources were used (e.g. lake sediments and wetland soil) (Opara et al., 2012). 3.5.

Methane production from coal by a single

Methane associated with coal beds is an important global resource of natural gas. Much of the methane in coal comes from microbial methanogenesis. Mayumi et al. characterized a strain of Methermicoccus shengliensis that, unexpectedly, is capable of making methane from the dozens of methoxylated aromatic compounds found in a variety of coal types (see the Perspective by Welte).

Methanogenesis - Current Biology

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 respiration, methanogenesis has some ...

Working Mine Methane Coal Mine Methane CMM

2021-3-1  Coal mine methane (CMM) is a type of gas present in active, working mine sites. This gas is extracted from the air in the coal mine helping improve safety and preventing uncontrolled release of methane to atmosphere. CMM is a mixture of methane air released during the process of coal mining and must be vented for safety reasons.

Biogenic methane production from coal: A review on

world’s total fossil fuel reserves are in the form of coal [1]. Among the estimated 3.6 trillion ton of total coal reserves in the United States (US) that underlay 13% of its land mass [2], only approxi-mately 236billion ton (6.6%) are viable to mine with current acqui-sition technologies. Estimation by US Department of Energy is a little ...

Bioconversion of coal to methane by microbial

Detection of methanogenic potential of coal bioconversion. To explore the biomethane production potential of coal from the opencast coal mine, five groups of cultures containing coal powder (0.3 g) and/or soil samples (0.5 g) as substrates were set up in the laboratory, while the microbial communities inhabiting the coal and/or soil were used for inoculation.
