Physiological, genomic, and sulfur isotopic characterization of methanol metabolism by Desulfovibrio carbinolicus.

PLoS ONE, 2021
Methanol is often considered as a non-competitive substrate for methanogenic archaea, but an increasing number of sulfate-reducing microorganisms (SRMs) have been reported to be capable of respiring with methanol as an electron donor.

Metagenomic Association Uncovers Host Genotype‐Structured Rhizobacterial Networks and Novel Taxa That Enhance Soybean Salt Tolerance

Advanced Science, EarlyView.
An STI‐guided metagenomic association framework links soybean salt‐tolerance phenotypes with rhizosphere microbiome composition and network organization in natural saline soils. The approach identifies candidate beneficial taxa, including Thalassospira xiamenensis, and provides an efficient strategy for mining stress‐protective microbes from native ...

Adaptive Cu Reconstruction in Heterostructure Drives High‐Rate Nitrate‐to‐Ammonia Conversion

Advanced Science, EarlyView.
An adaptively reconstructed Cu/CoOX heterojunction, featuring a surface‐localized, hydroxyl‐rich oxidized Cu species, forms in situ from a CuO/CoOX (Co1Cu9OX) pre‐catalyst during electrochemical nitrate reduction. The self‐adaptive reconstruction and the incorporation of heterostructure regulate nitrogen‐containing intermediate adsorption and *H supply,

Genesis of H2S in Jurassic associated gas in Pengyang area, Ordos Basin, NW China

Journal of Natural Gas Geoscience, 2022
The Jurassic Yan'an Formation (J1y) crude oil-associated gas in the Pengyang area of the Ordos Basin contains a certain amount of H2S. The study of its genesis is important for us to predict the distribution of H2S in Mesozoic in the basin.

Isotopic fractionations accompanying sulfur hydrolysis.

GEOCHEMICAL JOURNAL, 2000
In the direct hydrolysis of elemental sulfur, immediate precipitation of the sulfide as the copper salt allows measurement of the initial sulfur isotopic compositions of product sulfide and sulfate. δ34S values for product sulfide and sulfate and for parent elemental sulfur at reaction temperatures of 50 to 200°C differ by less than 3‰ and demonstrate ...

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Sulfur isotope analyses of individual aerosol particles in the urban aerosol at a central European site (Mainz, Germany) [PDF]

Atmospheric Chemistry and Physics, 2008
Sulfur isotope analysis of atmospheric aerosols is a well established tool for identifying sources of sulfur in the atmosphere, estimating emission factors, and tracing the spread of sulfur from anthropogenic sources through ecosystems.

Multiple Sulfur Isotope Records of the 3.22 Ga Moodies Group, Barberton Greenstone Belt

Geosciences, 2020
The Moodies Group, the uppermost unit in the Barberton Greenstone Belt (BGB) in South Africa, is a ~3.7-km-thick coarse clastic succession accumulated on terrestrial-to-shallow marine settings at around 3.22 Ga.

Fractionation of sulfur isotopes in the preparation of sulfur dioxide. An improved technique for the precision analysis of stable sulfur isotopes

GEOCHEMICAL JOURNAL, 1966
It is definitely shown that the main cause of error encountered in the precision isotope analysis of sulfur is in the isotope exchange reaction between SO2 and SO3 during the combustion process of SO2 preparation. The isotope fractionation factor between the two oxides is estimated to be 1.0035 at 1200°C.

Isotope fractionation and sulfur metabolism by pure and enrichment cultures of elemental sulfur‐disproportionating bacteria [PDF]

Limnology and Oceanography, 1998
We have explored the sulfur metabolism and accompanying fractionation of sulfur isotopes during the disproportionation of elemental sulfur by seven different enrichments and three pure bacterial cultures. Cultures were obtained from both marine and freshwater environments.
