Enhancement of methanogenesis by electric syntrophy with biogenic iron‐sulfide minerals

MicrobiologyOpen, 2019
Recent studies have shown that interspecies electron transfer between chemoheterotrophic bacteria and methanogenic archaea can be mediated by electric currents flowing through conductive iron oxides, a process termed electric syntrophy. In this study, we

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Methyl-Based Methanogenesis: an Ecological and Genomic Review [PDF]

Methyl-based methanogenesis is one of three broad categories of archaeal anaerobic methanogenesis, including both the methyl dismutation (methylotrophic) pathway and the methyl-reducing (also known as hydrogen-dependent methylotrophic) pathway.

Potential rates of methanogenesis in peat and marl sawgrass wetlands in the Florida Everglades [PDF]

, 1990
Methanogenesis was studied in soils from two sawgrass wetlands of the Florida Everglades. Marl soils exhibited a significantly higher potential rate of methanogenesis than peat soils.

Distinct Microbiota and Functional Pathway Profiles Define Success and Failure in Regenerative Endodontic Treatment

International Endodontic Journal, EarlyView.
ABSTRACT Aim To characterize the intracanal microbiota and identify key microbial taxa and functional pathways associated with regenerative endodontic treatment (RET) outcomes. Methodology In this observational cohort study, 196 samples were collected at five time points from external tooth surfaces (T1, T4) and root canals (T2, T3, T5).

Methanogenesis in the presence of oxygenic photosynthetic bacteria may contribute to global methane cycle

Nature Communications
Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from the anaerobic transformation of organic matters.

Varying effects of stream restoration on riparian soil carbon persistence and methane emissions in the southern Rocky Mountains, United States

Restoration Ecology, EarlyView.
Abstract Introduction Channel incision can disconnect streams from their floodplains, potentially depleting carbon (C) in riparian soils by stimulating microbial decomposition. Stream restoration may offer an opportunity to replenish soil C pools by saturating riparian soils with water and slowing microbial activity.

Environmental drivers of gaseous carbon fluxes in drained and rewetted Minnesota peatlands, U. S. A.

Restoration Ecology, EarlyView.
Abstract Introduction Rewetting shows promise for mitigating carbon loss from drained peatlands. However, knowledge gaps remain in rewetting impacts on gaseous carbon fluxes and factors affecting rewetting success, especially in Minnesota and the Upper Midwest, United States, despite abundant degraded peatlands presenting restoration opportunities ...

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

The use of direct-fed microbials for mitigation of ruminant methane emissions: a review

Animal, 2014
Concerns about the environmental effect and the economic burden of methane (CH4) emissions from ruminants are driving the search for ways to mitigate rumen methanogenesis.
