“…It was also found that Methanothermobacter appeared to be the most frequently encountered taxon in different samples of production water from petroleum reservoirs amended with zero-valent iron as the electron donor and was responsible for producing methane [26]. Moreover, active methanogenic activity conducted by Methanothermobacter was confirmed under the CCS conditions in petroleum reservoirs [27]. In the current study, the dominance of Methanothermobacter as the sole methanogen detected in all incubation cultures supported its competitive role in methane productionwith ethanol addition.…”

“…Methane was generated in all enrichments with the addition of ethanol after an initial lag phase of about 80 days, and 1.25, 327, 308, and 204 µmol of methane were accumulated in the treatments of S0, S30, S60, and S90, respectively, after 230 days of anaerobic incubation. The methane production rate and total amount of methane in the enrichments with the amendment of ethanol and bicarbonate (28.4 µmol CH 4 day −1 l −1 , 26.8 µmol CH 4 day −1 l −1 , and 17.7 µmol CH 4 day −1 l −1 in S30, S60, and S90, respectively) were much higher than those in S0 without bicarbonate, and they were much higher than previously reported biological methane production rates of 1.3-80 nmol CH 4 day −1 l −1 in subsurface petroleum reservoirs [27]. Maximum methane production occurred in S30, followed by S60, S90, and S0, which showed a similar trend with the amounts of consumed ethanol in the corresponding cultures, indicating that ethanol metabolism was directly or indirectly related to activities of methanogenesis under the experimental conditions.…”

Transformation of CO2 in both carbon capture and storage (CCS) to biogenic methane in petroleum reservoirs is an attractive and promising strategy for not only mitigating the greenhouse impact but also facilitating energy recovery in order to meet societal needs for energy. Available sources of petroleum in the reservoirs reduction play an essential role in the biotransformation of CO2 stored in petroleum reservoirs into clean energy methane. Here, the feasibility and potential on the reduction of CO2 injected into methane as bioenergy by indigenous microorganisms residing in oilfields in the presence of the fermentative metabolite ethanol were assessed in high-temperature petroleum reservoir production water. The bio-methane production from CO2 was achieved in enrichment with ethanol as the hydrogen source by syntrophic cooperation between the fermentative bacterium Synergistetes and CO2-reducing Methanothermobacter via interspecies hydrogen transfer based upon analyses of molecular microbiology and stable carbon isotope labeling. The thermodynamic analysis shows that CO2-reducing methanogenesis and the methanogenic metabolism of ethanol are mutually beneficial at a low concentration of injected CO2 but inhibited by the high partial pressure of CO2. Our results offer a potentially valuable opportunity for clean bioenergy recovery from CCS in oilfields.

“…Pure-culture experiments were performed to examine factors influencing the ability of cells to survive exposure to high-pressure CO 2 (Santillan et al, 2013). Experiments were conducted with three model organisms: Shewanella oneidensis strain MR-1 (ATCC BA-1096), thermoautitrophicus have been detected in the deep subsurface (Kawaguchi et al, 2010;Nazina et al, 2001). S. oneidensis is widespread in soils and shallow sediment and has been studied within the context of CO 2 leakage to shallow groundwater from deep storage (Wu et al, 2010).…”

Researchers at the Center for Frontiers of Subsurface Energy Security (CFSES) have conducted laboratory and modeling studies to better understand the interplay between microorganisms and geochemistry for geological carbon storage (GCS). We provide evidence of microorganisms adapting to high pressure CO conditions and identify factors that may influence survival of cells to CO 2 stress. Factors that influenced the ability of cells to survive exposure to high-pressure CO 2 in our experiments include mineralogy, the permeability of cell walls and/or membranes, intracellular buffering capacity, and whether cells live planktonically or within biofilm. Column experiments show that, following exposure to acidic water, biomass can remain intact in porous media and continue to alter hydraulic conductivity. Our research also shows that geochemical changes triggered by CO 2 injection can alter energy available to populations of subsurface anaerobes and that microbial feedbacks on this effect can influence carbon storage. Our research documents the impact of CO 2 on microorganisms and in turn, how subsurface microorganisms can influence GCS. We conclude that microbial presence and activities can have important implications on carbon storage and that their presence should not be overlooked in further GCS research.

“…Biological transformation of CO2 into value-added products such as biomethane. In biological processes, CH4 is a handy energy source produced by hydrogenotrophic methanogens using CO2 or CO as carbon and H2 as energy sources [7][8]. In addition, several studies have focused on a methanation reaction because of its important implications for energy and the environment [9].…”

Using carbon dioxide (CO2) as a carbon source for renewable energy production has potential applications for CO2 sequestration and greenhouse gas (GHG) emission reduction. In biological conversion, CO2 can be transformed into methane (CH4) by hydrogenotrophic methanogens with hydrogen (H2) as an energy source. In this study, zero-valent iron (ZVI) of 16, 32, 64, and 96 g/L was used as the H2 energy source for a bioconversion of CO2 to CH4. When the ZVI dosage was increased, a decrease in CO2 in the headspace occurred simultaneously with the increase in CH4. The presence of CH4 in both CO2/H2 and CO2/ZVI indicates that hydrogenotrophic methanogens can utilize both ZVI and H2 as electron donors and convert CO2 to CH4. The highest methane yield of 1.728 mmol CH4/mmol CO2 was observed for the CO2/ZVI 96 g/L. The modified Gompertz equation fitted the cumulative CH4 production curves of CO2/H2 and CO2/ZVI very well, where R2 was 0.9915 and 0.9903-0.9968, respectively. 16S rDNA high-throughput sequencing results revealed that ZVI addition facilitated the increase of the family Methanobacteriaceae, which became the most abundant among other archaea. It points out that this family favors ZVI and utilizes electrons more effectively from ZVI than H2.
