Long-term carbon and nitrogen dynamics at SPRUCE revealed through stable isotopes in peat profiles [PDF]

, 2017
Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to ...

Evaluation of ammonium removal from sludge return liquor using a pilot‐scale microbial electrolysis cell

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 3, Page 638-648, March 2026.
Abstract BACKGROUND Microbial electrochemical technologies (METs) enable separation of ammonium from nutrient‐rich waste streams, such as sludge return liquors, using bioanodes that consume organic matter to generate electrical current. Quantification of ammonia recovery performance in pilot scale METs treating real wastes under industrially relevant ...

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.

Early‐Life Respiratory Emissions of CO₂, CH₄, and N₂O in Pre‐Weaned Dairy‐Bred Calves

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Greenhouse gas (GHG) emissions from livestock are a major contributor to climate change, with cattle known to be the principal contributor through enteric fermentation, manure management, and metabolic processes. This study investigates the emission rates of CO₂, CH₄, and N₂O in pre‐weaned calves aged 12 to 86 days, focusing on the ...

Reactivity and fate of secondary alkane sulfonates (SAS) in marine sediments [PDF]

, 2014
This research is focused on secondary alkane sulfonates (SAS), anionic surfactants widely used in household applications that access aquatic environments mainly via sewage discharges.We studied their sorption capacity and anaerobic degradation in marine ...

Effect of Diet Neutral Detergent Fibre Content on Dry Matter Intake, Nutrient Digestibility, Growth Efficiency and Carcass Characteristics of Finishing South African Mutton Merino Wether Lambs

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Feeding South African Mutton Merino lambs low‐NDF lucerne hay diets improved nutrient digestibility, energy utilisation, growth efficiency, and carcass quality. Despite lower intake at the lowest NDF level, fibre digestibility and feed conversion improved, indicating that highly digestible, low‐NDF finishing diets enhance lamb growth and carcass traits.

NanoFe3O4 as Solid Electron Shuttles to Accelerate Acetotrophic Methanogenesis by Methanosarcina barkeri

Frontiers in Microbiology, 2019
Magnetite nanoparticles (nanoFe3O4) have been reported to facilitate direct interspecies electron transfer (DIET) between syntrophic bacteria and methanogens thereby improving syntrophic methanogenesis.

Slantwise Convection and Heat Transport in Icy Moon Oceans

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.
