Characterization of Anthracite-Degrading Methanogenic Microflora Enriched from Qinshui Basin in China

Microorganisms are essential for the formation of biogenic coalbed methane (CBM) and the application of microbially enhanced CBM (MECoM). Anthracite-degrading methanogenic microflora was cultivated by enrichment and subculture from produced water obtained in Qinshui Basin where CBM is explored commercially. The maximum methane yield was 255 μmol/g of coal after 23 days of cultivation at 35 °C, 1.1–1.2% of salinity, <0.15 mm of coal particle...
