Available methane from anthracite by combining coal seam microflora and H2O2 pretreatment
The conversion of coal to methane by anaerobic microorganisms is an efficient, clean, and green way to utilize coal. However, methane production is relatively low due to the low bioavailability of
Enhancing Biomethane Production From Lignite by an Anaerobic Polycyclic Aromatic Hydrocarbon Degrading Fungal Flora Enriched From Produced Water
The coal-degrading ability of microorganisms is essential for the formation of biogenic coalbed methane. The ability to degrade the aromatic compound of coal is more important because it is perceived
Contribution of Yeast Extract, Activated Carbon, and an Electrostatic Field to Interspecies Electron Transfer for the Bioelectrochemical Conversion of Coal to Methane
The bioelectrochemical conversion of coal to methane was investigated in an anaerobic batch reactor containing yeast extract and activated carbon. In anaerobic degradation of coal, yeast extract was
Bioelectrochemical Enhancement of Biogenic Methane Conversion of Coal
This study demonstrated the enhancement of biogenic coal conversion to methane in a bioelectrochemical anaerobic reactor with polarized electrodes. The electrode with 1.0 V polarization increased the
On Comparison Between Fungal and Bacterial Pretreatment of Coal for Enhanced Biogenic Methane Generation
ABSTRACT Owing to better understanding of subsurface geochemical carbon recycling and real-time active methanogenesis in major coal basins around the globe, substantial share of subsurface methane
Biogenic methane generation using solutions from column reactions of lignite with hydrogen peroxide
An operative laboratory investigation of bioconversion route from waste coal to natural energy
Purpose In the present research, the potential of reactivated consortium for the methane production consuming waste coal as a carbon source (1% w/v) in the modified media at mesophilic temperature


Stimulation of Methane Generation from Nonproductive Coal by Addition of Nutrients or a Microbial Consortium
It is indicated that methane production could be stimulated at the nonproductive field site and that low microbial biomass may be limiting in situ methane generation, and the microcosm study suggests that the pathway for generating methane from coal involves complex microbial partnerships.
The alkaloid gramine in the anaerobic digestion process—inhibition and adaptation of the methanogenic community
In this study, the alkaloid gramine was added daily to a continuous co-digestion of grass silage and cow manure and the methanogenic community changed from a well-balanced mixture of five phylotypes towards a strong dominance of Methanosarcina while Methanosaeta disappeared.
Polycyclic Aromatic Hydrocarbon Affects Acetic Acid Production during Anaerobic Fermentation of Waste Activated Sludge by Altering Activity and Viability of Acetogen.
Mechanism exploration revealed that the present phenanthrene mainly affected the acidification process of anaerobic fermentation and caused the shift of the microbial community to benefit the accumulation of acetic acid.
Bioconversion of coal: new insights from a core flooding study
A pressurized core flooding experiment was performed to better understand in situ coal bioconversion processes. The core flooding experiment was conducted using a biaxial core holder packed with
Acetogens and Acetoclastic Methanosarcinales Govern Methane Formation in Abandoned Coal Mines
The methanogenic microbial community appears to be highly adapted to the low-H2 conditions found in coal mines, and the formation of [ 13C]methane was linked to acetoclastic methanogenesis in both the [13C]acetate- and the H2-13CO2-amended cultures of coal and timber.
