摘要:Abstract(#br)Subsurface coal environments, where biogenic coal-to-methane conversion occurs, are difficult to access, resulting in inherent challenges and expenses for in situ experiments. Previous batch reactor studies provided insights into specific processes, pathways, ki...

摘要:Abstract(#br)Many coal beds contain microbial communities that can convert coal to natural gas (coalbed methane). Native microorganisms were obtained from Powder River Basin (PRB) coal seams with a diffusive microbial sampler placed downhole and used as an inoculum for enrichment...

摘要:Abstract(#br)Slow rates of coal-to-methane conversion limit biogenic methane production from coalbeds. This study demonstrates that rates of coal-to-methane conversion can be increased by the addition of small amounts of organic amendments. Algae, cyanobacteria, yeast cells, and ...

摘要:Abstract(#br)Understanding microbial community structure and function within the subsurface is critical to assessing overall quality and maintenance of groundwater; however, the factors that determine microbial community assembly, structure, and function in groundwater systems an...

摘要:Abstract(#br)Coalbed methane (CBM) makes up a significant portion of the world’s natural gas resources. The discovery that approximately 20% of natural gas is microbial in origin has led to interest in microbially enhanced CBM (MECoM), which involves stimulating microorganis...

摘要:Abstract(#br)Biogenic coalbed methane (CBM), a microbially-generated source of natural gas trapped within coal beds, is an important energy resource in many countries. Specific bacterial populations and enzymes involved in coal degradation, the potential rate-limiting step o...

摘要:Abstract(#br)Microbial communities were characterized at contaminated sites that had elevated levels of nitrate, nickel, aluminum, and uranium (up to 690 mM, 310 μM, 42 mM, and 30 μM, respectively). The bacterial community structure based upon clonal libraries of the SSU rRN...

摘要:Abstract(#br)The glucomannokinase gene of Prevotella bryantii B 1 4, a strictly anaerobic ruminal bacterium, was amplified with degenerate PCR primers. The degenerate PCR primers were based on the N-terminal amino acid residues of the purified glucomannokinase and the C-term...

摘要:Abstract(#br)Prevotella bryantii B 1 4 grew faster on glucose than mannose (0.70 versus 0.45 h −1 ), but these sugars were used simultaneously rather than diauxically. 2-deoxy-glucose (2DG) decreased the growth rate of cells that were provided with either glucose or mannose,...

摘要:Abstract(#br)Little is known about how bacteria degrade structural polysaccharides or the regulatory systems that control this degradation. Bacteroides xylanolyticus X5-1 is a Gram-negative, anaerobic bacterium that can grow on structural polysaccharides such as xylan and pectin....
