Nitrate addition inhibited methanogenesis in paddy soils under long-term managements

Plant, Soil and Environment, 2018
Rice fields are a major source of atmospheric methane (CH4). Nitrate has been approved to inhibit CH4 production from paddy soils, while fertilization as well as water management can also affect the methanogenesis.

Resource Recovery From Food Processing Wastewater Through Microalgae‐Driven Carbon Chain Rearrangement

GCB Bioenergy, Volume 18, Issue 10, October 2026.
Carbon chain rearrangement reframes food‐processing wastewater treatment from COD removal to controlled carbon recovery. By coupling microalgal biosynthesis with bacterial substrate transformation, algal–bacterial consortia can redirect heterogeneous wastewater carbon toward recoverable biomolecules.

Use of some novel alternative electron sinks to inhibit ruminal methanogenesis [PDF]

Reproduction Nutrition Development, 2003
Several compounds were evaluated in vitro as alternative electron sinks to ruminal methanogenesis. They were incubated with ruminal fluid, buffer mixture, and finely ground alfalfa hay for 24 h, at 0, 6, 12, and 18 mM initial concentrations. The propionate enhancer oxaloacetic acid, the butyrate enhancer beta-hydroxybutyrate, and the butyrate ...

Overcoming Extreme Ammonia Inhibition on Methanogenesis by Artificially Constructing a Synergistically Community with Acidogenic Bacteria and Hydrogenotrophic Archaea

Advanced Science
High total ammonia nitrogen (TAN) inhibits anaerobic digestion (AD) and cannot be completely eliminated by merely enhancing a stage of AD. This study incorporates TAN‐tolerant inoculum into substrates hydrolyzed by Rhizopus mixed agents to simultaneously

Spatial and temporal patterns of bottom water euxinia in shallow areas of the southwestern Baltic Sea

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Sediments in productive coastal regions are hotspots of hydrogen sulfide (H2S) production through microbial sulfate reduction. Under anoxic seafloor conditions, H2S can escape the sediment and accumulate in bottom waters, where elevated concentrations render the benthic environment toxic, posing ecological and economic risks.

Polyphenol-Containing Feed Additive Polygain™ Reduces Methane Production and Intensity from Grazing Dairy Cows Measured Using an Inverse-Dispersion Technique

Animals
This study, conducted on a commercial dairy farm using a robotic milking system in Victoria, Australia, examined the effects of Polygain™ (The Product Makers Australia), a polyphenol-rich sugarcane feed material (PRSFM), on CH4 emissions in grazing dairy

Role of methanotrophy in a high‐methane emitting thermokarst lake

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Thermokarst (thaw) lakes are projected to be an increasing source of atmospheric methane (CH4), a potent greenhouse gas, as climate warms and permafrost thaws. However, the magnitude of CH4 cycling, particularly the role of aerobic CH4 oxidation (methanotrophy), among thermokarst lakes, is not well constrained.

Higher methanotroph abundance and bottom‐water methane in ponds with floating photovoltaic arrays

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Floating photovoltaic (FPV) arrays alter the methane (CH4) cycling dynamics of waterbodies on which they are deployed. Here, we investigated dissolved CH4 dynamics and associated CH4 cycling microbial communities (methanogens and methanotrophs) in the 2nd year of FPV deployment (70% aerial coverage) in experimental ponds.

Jump in Tropospheric Methane Concentrations in 2020–2021 and Slowdown in 2022–2024: New Hypotheses on Causation

Atmosphere
Earth’s atmospheric methane (CH4) concentration has risen more than 162% since pre-industrial levels in the mid-18th century, and about 30% of the rise in global temperatures since the pre-industrial era is due to CH4 The build-up of methane in the ...

A theoretical comparison between two ruminal electron sinks

Frontiers in Microbiology, 2013
Dihydrogen accumulation resulting from methanogenesis inhibition in the rumen is an energy loss and can inhibit fermentation. The objective of this analysis was to compare the energetic and nutritional consequences of incorporating H2 into reductive ...
