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,

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.

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).

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 ...

Response of methane emissions, redox potential, and pH to eucalyptus biochar and rice straw addition in a paddy soil [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 This study aims to comprehend the links between soil Eh and pH changes in eucalyptus biochar (BC) and rice straw (RS) amended soils and CH4 emissions. Increased CH4 emission rates and high total CH4 emissions (TCH4 ) were found in RS soils.

Climate benefits of wetland restoration are constrained by slow vegetation recovery
Restoration Ecology, EarlyView.Abstract Introduction Wetland restoration is widely used to enhance ecosystem resilience, biodiversity, and climate mitigation. However, restoring hydrology may not lead to rapid vegetation establishment or reduced greenhouse gas (GHG) emissions in severely degraded wetlands.

Genetic resources for methane production from biomass described with gene ontology
Frontiers in Microbiology, 2014 Methane (CH4) is a valuable fuel, constituting 70-95% of natural gas, and a potent greenhouse gas. Release of CH4 into the atmosphere contributes to climate change.

Hydrogenotrophic Methanogenesis Under Alkaline Conditions
Frontiers in Microbiology, 2020 A cement-based geological disposal facility (GDF) is one potential option for the disposal of intermediate level radioactive wastes. The presence of both organic and metallic materials within a GDF provides the opportunity for both acetoclastic and ...
