Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...

Dissolved Trivalent Manganese Under Defined Redox Conditions in Redoximorphic Soils: Laboratory and Field Evidence

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT The reduction–oxidation (redox) cycling of manganese (Mn) regulates biogeochemical element cycles, including the carbon cycle, in soils. Dissolved trivalent Mn (Mn3+), stabilised by complexation with natural organic ligands (NOLs), is a key component mediating these processes. Accurate quantification of this species is therefore needed.

Floodplain reforestation reduces nitrate loss through soil microbial pathways

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Reforesting floodplains with native Melaleuca substantially reduced nitrate leaching relative to sugarcane, driven by higher soil organic carbon supporting decomposer‐dominated microbial communities that immobilise nitrogen rather than converting it to leachable nitrate.

Evidence for life in the isotopic analysis of surface sulphates in the Haughton impact structure, and potential applications on Mars [PDF]

open access: yes, 2012
The analysis of sulphur isotopic compositions in three sets of surface sulphate samples from the soil zone in the Haughton impact structure shows that they are distinct.

Isotopic Fractionation Associated With Sulfate Import and Activation by Desulfovibrio vulgaris str. Hildenborough

open access: yesFrontiers in Microbiology, 2020
The use of stable isotopes to trace biogeochemical sulfur cycling relies on an understanding of how isotopic fractionation is imposed by metabolic networks.

Protection and Delivery of Phytochemicals from Passive Encapsulation to Guaranteed Self‐Assembly Induced by Amyloid Template for Chronic Disease Prevention via Modulating Microbial‐Host Crosstalk

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
ABSTRACT The rising incidence of chronic diseases globally has drawn widespread attention to phytochemicals, which exert targeted preventive and alleviating effect by modulating gut microbiota; thus, a potential strategy for precision nutritional interventions is offered.

Assimilatory sulfate reduction in the marine methanogen Methanothermococcus thermolithotrophicus

open access: yes, 2023
Methanothermococcus thermolithotrophicus is the only known methanogen that grows on sulfate as its sole sulfur source, uniquely uniting methanogenesis and sulfate reduction.

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

open access: yesChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Novel insights into dissimilatory sulfite reduction [PDF]

open access: yes, 2015
Life on Earth is extremely diverse, as organisms had to adapt to a panoply of different environmental niches. There are several mechanisms by which organisms grow in the absence of oxygen, one of which is the dissimilatory reduction of sulfate to sulfide,

Biodegradation of the Alkaline Cellulose Degradation Products Generated during Radioactive Waste Disposal.

open access: yes, 2014
The anoxic, alkaline hydrolysis of cellulosic materials generates a range of cellulose degradation products (CDP) including α and β forms of isosaccharinic acid (ISA) and is expected to occur in radioactive waste disposal sites receiving intermediate ...
