“…However, in contrast with the Strąpoć model, we did not observe PAH or ketones in the microcosm solution. Instead, we observed single-ring aromatics, long-chain alkanes, and long-chain fatty acids that accumulated during the first 39 days and were then degraded (33).…”

“…The dichloromethane extracts were analyzed by gas chromatography-mass spectrometry for identification of organic compounds as previously described (34). Volatile free fatty acids (formic, acetic, propionic, and butyric) were analyzed on acidified samples using high-performance liquid chromatography-mass spectrometry as previously described (33).…”

“…Long-chain alkanes (C 22 to C 36 ), phenols, phthalates, and sterol precursors typical of plant material (such as squalene, stigmasterol, and sitosterol) were also present in solution. These signature peaks were gone by day 78 (33). No polyaromatic hydrocarbons were detected in the microcosm solutions.…”

Biogenic formation of methane from coal is of great interest as an underexploited source of clean energy. The goal of some coal bed producers is to extend coal bed methane productivity and to utilize hydrocarbon wastes such as coal slurry to generate new methane. However, the process and factors controlling the process, and thus ways to stimulate it, are poorly understood. Subbituminous coal from a nonproductive well in south Texas was stimulated to produce methane in microcosms when the native population was supplemented with nutrients (biostimulation) or when nutrients and a consortium of bacteria and methanogens enriched from wetland sediment were added (bioaugmentation). The native population enriched by nutrient addition included Pseudomonas spp., Veillonellaceae, and Methanosarcina barkeri. The bioaugmented microcosm generated methane more rapidly and to a higher concentration than the biostimulated microcosm. Dissolved organics, including long-chain fatty acids, single-ring aromatics, and long-chain alkanes accumulated in the first 39 days of the bioaugmented microcosm and were then degraded, accompanied by generation of methane. The bioaugmented microcosm was dominated by Geobacter sp., and most of the methane generation was associated with growth of Methanosaeta concilii. The ability of the bioaugmentation culture to produce methane from coal intermediates was confirmed in incubations of culture with representative organic compounds. This study indicates that methane production could be stimulated at the nonproductive field site and that low microbial biomass may be limiting in situ methane generation. In addition, the microcosm study suggests that the pathway for generating methane from coal involves complex microbial partnerships.

“…Water washing is also important from the perspective that it can displace organic intermediate accumulations that serve as precursors for methanogenic substrates such as acetate and H 2 (e.g. Furmann et al, 2013a;Gao et al, 2013;Orem et al, 2010). In the preliminary Walloon trial (Papendick et al, 2011), Taroom coal inoculated with Roma region formation water generated methane at rates of up to 0.9m 3 /t/day with overall yields of 3.64 to 6.17 m 3 /t.…”

“…In addition, bulk community growth can be studied by thymidine incorporation. As microbial communities in these experiments, we will use both the natural indigenous microbial population and microbial inoculates that have been tested in coal-to-methane degradation (e.g., Jones et al, 2008aJones et al, , 2008bOrem et al, 2010). The inocula also include mesophilic to thermophilic methanogens isolated from subseafloor sediments in shallow zones of the same drilling site (C9001) and from high-CO 2 hydrothermal fluids in the Okinawa Trough hydrothermal fields.…”
