Oil Has a Higher Methanogenic Potential than Coal in an Oil-Bearing Coal Seam.

ABSTRACT: The presence of oil in coal seams from coal-oil symbiosis areas poses a serious threat to the safe and efficient mining of coal. However, the information about the application of microbial technology in oil-bearing coal seams was insufficient. In this study, the biological methanogenic potential of coal and oil samples in an oil-bearing coal seam was analyzed by anaerobic incubation experiments. The results showed that the biological methanogenic efficiency of the coal sample increased from 0.74 to 1.06 from day 20 to day 90, and the biological methanogenic potential of the oil sample was about twice as high as that of the coal sample after 40 days of incubation. The Shannon diversity and observed operational taxonomic unit (OTU) number of oil were lower than those in coal. The major gener
