dMicrobially produced methane, a versatile, cleaner-burning alternative energy resource to fossil fuels, is sourced from a variety of natural and engineered ecosystems, including marine sediments, anaerobic digesters, shales, and coalbeds. There is a prevailing interest in developing environmental biotechnologies to enhance methane production. Here, we use small-subunit rRNA gene sequencing and metagenomics to better describe the interplay between coalbed methane (CBM) well conditions and microbial communities in the Alberta Basin. Our results show that CBM microbial community structures display patterns of endemism and habitat selection across the Alberta Basin, consistent with observations from other geographical locations. While some phylum-level taxonomic patterns were observed, relative abundances of specific taxonomic groups were localized to discrete wells, likely shaped by local environmental conditions, such as coal rank and depth-dependent physicochemical conditions. To better resolve functional potential within the CBM milieu, a metagenome from a deep volatile-bituminous coal sample was generated. This sample was dominated by Rhodobacteraceae genotypes, resolving a near-complete population genome bin related to Celeribacter sp. that encoded metabolic pathways for the degradation of a wide range of aromatic compounds and the production of methanogenic substrates via acidogenic fermentation. Genomic comparisons between the Celeribacter sp. population genome and related organisms isolated from different environments reflected habitat-specific selection pressures that included nitrogen availability and the ability to utilize diverse carbon substrates. Taken together, our observations reveal that both endemism and metabolic specialization should be considered in the development of biostimulation strategies for nonproductive wells or for those with declining productivity.T he deposition of plant-derived organic matter over geological time has resulted in the formation of stratified hydrocarbon resource environments known as coalbeds. This prevalent energy resource has fueled human development for thousands of years with concomitant environmental impacts, including landscape alteration, waste production, and greenhouse gas emissions (1, 2). In contrast to solid fuel, cleaner-burning coalbed methane (CBM) has become an increasingly attractive global energy resource. While some fraction of CBM is produced under thermogenic conditions, recent studies indicate that microbial communities inhabiting coalbed ecosystems contribute substantially to methane production (3). This has sparked both scientific and biotechnological interest in coalbed microbial communities to enhance CBM production from wells with low methane content or declining productivity (4-6).Microbial diversity surveys using small-subunit rRNA (SSU; or 16S rRNA) gene sequencing have been conducted across geographically distinct coalbed ecosystems (7-11) and enrichment cultures (6, 12). Taxonomic groups, including Firmicutes, Spirochetes, Bacteroidete...

“…Biogenic CH 4 is generated through anaerobic microbial process of methanogenesis and constitutes a significant fraction of the natural gas reserves. It is generally accepted that biogenic coalbed CH 4 is a product of coal biodegradation by methanogenic archaea and syntrophic bacteria inhabiting coal beds . These microorganisms artificially stimulate the regeneration of biogenic coalbed CH 4 .…”

The global warming is directly related to the increased greenhouse gas emissions from both natural and anthropogenic origins. There has been a drastic rise in the concentration of CO 2 and other greenhouse gases since the industrial revolution primarily due to the intensifying consumption of fossil fuels. With the need to reduce carbon emissions and mitigate global warming certain strategies relating to carbon capturing and sequestration are indispensable. This paper comprehensively describes several physicochemical, biological and geological routes for carbon capture and sequestration. The trend of the increase in greenhouse gases over the years is illustrated along with the global statistics for fossil fuels usage and biofuels production. The physicochemical carbon capturing technologies discussed include absorption, adsorption, membrane separation and cryogenic distillation. The algal and bacterial systems, dedicated energy crops and coalbed methanogenesis have been vividly explained as the biological routes for carbon sequestration. The geological carbon sequestering route centers on biochar application and oceanic carbon storage. A systematic survey has been made on the origin and impact of greenhouse gases along with the potential for sequestration based on some fast-track and long-term sequestration technologies. 100
