Metal-driven anaerobic oxidation of methane and the Sturtian deglaciation

Nature Communications
The Sturtian and Marinoan glaciations shaped Neoproterozoic palaeoenvironmental evolution. While methane emission likely intensified the Marinoan greenhouse effect, its role during the Sturtian glaciation—coinciding with widespread iron formations (IFs ...

Reduction of methane emission from landfills using bio-mitigation systems – from lab tests to full scale implementation [PDF]

, 2014
Landfills are significant sources of methane, which contributes to climate change. As an alternative to mitigation by gas utilization systems, bio-mitigation systems may be implemented.

Effects of Fertilization and Wheat Straw Management on Rice Yield and Greenhouse Gas Emissions in Paddy Fields

Land Degradation &Development, EarlyView.
ABSTRACT Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction ...

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Persistent activity of aerobic methane-oxidizing bacteria in anoxic lake waters due to metabolic versatility

Nature Communications
Lacustrine methane emissions are strongly mitigated by aerobic methane-oxidizing bacteria (MOB) that are typically most active at the oxic-anoxic interface.

Reducing Ammonia Emission during Food Waste Composting and Enhancing Compost Quality Using Different Additives

ChemistryOpen, EarlyView.
This research successfully reduces the ammonia emission by 45% and achieves good quality compost using additives (lactic acid or acetic acid) and bulking agents (mature compost or sawdust). The study supports Sustainable Development Goals 12 and 13 by promoting waste‐to‐resource option.

Vertical distribution of methanotrophic archaea in an iron-rich groundwater discharge zone.

PLoS ONE
Anaerobic oxidation of methane coupled to iron reduction (Fe-AOM) is a crucial process for methane removal in terrestrial environments. However, the occurrence of Fe-AOM in natural environments is rare, and the mechanisms behind the direct coupling of ...

Climate‐smart land management: Greenhouse gas outcomes and social and economic pathways to adoption

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change poses one of the greatest threats to natural and working lands, reducing the resilience of agricultural and forest productivity. Because land management is a leading source of greenhouse gas (GHG) emissions, climate‐smart management practices are being implemented to reduce net emissions while sustaining yields.

Inhibition Experiments on Anaerobic Methane Oxidation [PDF]

, 1985
Anaerobic methane oxidation is a general process important in controlling fluxes of methane from anoxic marine sediments. The responsible organism has not been isolated, and little is known about the electron acceptors and substrates involved in the ...

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

Sustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...
