“…This semi-quantitative empirical relationship has been reported by Aravena et al (2003) and Strąpoć et al (2007), and describes the overall hydrogen isotopic fractionation along the transfer of waterderived hydrogen through intermediary reactions into biogenic methane produced by H 2 -using methanogens. These carbon and hydrogen isotopic fractionations indicate that H 2 /CO 2 -using methanogenesis is responsible for the gas composition.…”

To identify the methanogenic pathways present in a deep aquifer associated with an accretionary prism in Southwest Japan, a series of geochemical and microbiological studies of natural gas and groundwater derived from a deep aquifer were performed. Stable carbon isotopic analysis of methane in the natural gas and dissolved inorganic carbon (mainly bicarbonate) in groundwater suggested that the methane was derived from both thermogenic and biogenic processes. Archaeal 16S rRNA gene analysis revealed the dominance of H 2 -using methanogens in the groundwater. Furthermore, the high potential of methane production by H 2 -using methanogens was shown in enrichments using groundwater amended with H 2 and CO 2 . Bacterial 16S rRNA gene analysis showed that fermentative bacteria inhabited the deep aquifer. Anaerobic incubations using groundwater amended with organic substrates and bromoethanesulfonate (a methanogen inhibitor) suggested a high potential of H 2 and CO 2 generation by fermentative bacteria. To confirm whether or not methane is produced by a syntrophic consortium of H 2 -producing fermentative bacteria and H 2 -using methanogens, anaerobic incubations using the groundwater amended with organic substrates were performed. Consequently, H 2 accumulation and rapid methane production were observed in these enrichments incubated at 55 and 65 1C. Thus, our results suggested that past and ongoing syntrophic biodegradation of organic compounds by H 2 -producing fermentative bacteria and H 2 -using methanogens, as well as a thermogenic reaction, contributes to the significant methane reserves in the deep aquifer associated with the accretionary prism in Southwest Japan.

“…Biogenic CBM has been found in many CBM reservoirs (Strapoć et al, 2011). It is the predominant gas in such reservoirs as the Illinois Basin (Strapoć et al, 2007) and the Powder River Basin . Studies both in the laboratory (Green et al, 2008;Harris et al, 2008;Jones et al, 2008) and in situ (Pfeiffer et al, 2010) showed that the microbes inhabiting coal beds were essential for the regeneration of biogenic CBM.…”

a b s t r a c t a r t i c l e i n f oIt is generally believed that biogenic coal bed methane (CBM) is an end product of coal biodegradation by methanogenic archaea and syntrophic bacteria. In this work, the archaeal and bacterial communities of CBM reservoir associated with Ordos Basin in China were investigated using 454 pyrosequencing. Sampling produced water, coal and rock in the reservoir, a total of 46,598 sequence reads were obtained. All archaea were methanogens with the genus Methanolobus predominating. The genus consisted of 81.18% of pyrosequencing reads in water sample and > 99% in coal and rock samples. Although the phylum Proteobacteria was the main component of all samples, bacterial communities in coal and rock samples were similar at the genus level, which were distinctly separated with water sample. The results strongly suggested that methylotrophic methanogenesis governed the biogenic CBM formation. The separation of microbial communities between water and coal, rock samples should be considered when investigating the process of coal biodegradation and the generation of new biogenic CBM.
