“…Both bacterial diversity and communities within both coal and rock were similar as revealed by the Chao1 estimators and the contribution of OTUs and genera. These were consistent with the previous study of Klein et al (2008) and Li et al (2008) who reported the distinct composition of microbial communities in coal and produced water from CBM reservoirs. The higher microbial diversity in coal and rock compared to produced water might be due to the existence of more ecological niches in coal and rock than in water.…”

“…However, most such studies used conventional molecular methods and sampled produced water drilled from CBM wells. Little was known about microbial communities inhabiting coal and rock (Klein et al, 2008;Li et al, 2008;Penner et al, 2010). In this study, produced water, coal and rock samples (SXLL-W, SXLL-C and SXLL-R, respectively) were obtained and analyzed using 454 pyrosequencing, in order to obtain more complete information about the microbial communities associated with the CBM reservoir in the Ordos Basin (Fig.…”

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.

“…Inferred groundwater recharge events in the Middle Jurassic and mid-Cretaceous-Recent (e.g. Faiz and Hendry, 2006;Kinnon et al, 2010;Li et al, 2008) likely played important roles in microbial gas generation and retention but this has not been explored in the literature. This paper represents the culmination of a stepwise basin analysis project ultimately aimed at siting potential in situ bioreactor locations.…”

Coal-bed methane (CBM) has emerged as a globally important source of natural gas, and recent studies have revealed that microbial production of methane in CBM formations plays a significant role. Coal-bed formations are complex ecosystems with large reservoirs of organic substrates comprised of aliphatic, aromatic, and heterocyclic compounds. The biotransformation of this organic matter to methane by microbial communities, however, is not well elucidated. The latter has important implications with regard to energy recovery from subsurface environments. Although coal beds and other deep subsurface systems pose significant challenges with respect to field sampling and analysis, recent methodological advances have provided novel insights into the ecology and metabolism of coal-bed microbial communities. Specifically, the availability of affordable sequencing technologies and advances in mass spectrometry have allowed an unprecedented ability to study in situ processes governing microbial metabolism in subsurface environments. The following protocols include methodologies for the collection of coal-bed-produced water for traditional cultivation and most probable number (MPN) techniques, community DNA extraction and sequence-based molecular analyses, and metabolite profiling. The described techniques are intended as primers for several cultivation, molecular, and mass spectrometry applications and are adaptable to a range of field and experimental conditions.
