Five-S-isotope evidence of two distinct mass-independent sulfur isotope effects and implications for the modern and Archean atmospheres. [PDF]
Proc Natl Acad Sci U S A, 2018 The signature of mass-independent fractionation of quadruple sulfur stable isotopes (S-MIF) in Archean rocks, ice cores, and Martian meteorites provides a unique probe of the oxygen and sulfur cycles in the terrestrial and Martian paleoatmospheres.

Sulfur Isotope Effects of Dissimilatory Sulfite Reductase. [PDF]
Front Microbiol, 2015 AbstractThe precise interpretation of environmental sulfur isotope records requires a quantitative understanding of the biochemical controls on sulfur isotope fractionation by the principle isotope-fractionating process within the S cycle, microbial sulfate reduction (MSR).

Sulfur Stable Isotope Discrimination in Rice: A Sulfur Isotope Mass Balance Study. [PDF]
Front Plant Sci, 2022 The use of sulfur (S) stable isotopes to study S metabolism in plants is still limited by the relatively small number of studies. It is generally accepted that less S stable isotope discrimination occurs during sulfate (SO42–) uptake. However, S metabolism and allocation are expected to produce separations of S stable isotopes among the different plant

Sulfur isotope composition in the Plesenci native sulfur mineral deposit, Republic of Macedonia [PDF]
, 2015 For the first time, we present our findings of the origin of sulfur in the gypsum and native sulfur within the Plesenci deposit, R.Macedonia. There we made a series of complex research and analysis of the light isotope (32S), heavy isotope (34S), and ...

Hydrogen and oxygen isotope ratios of thermal waters of Okayama Prefecture, Japan [PDF]
, 1999 Hydrogen and oxygen isotope rations of thermal waters from 46 spas in Okayama Prefecture range from -62.6 to -29.2% in δD and from -10.0 to -4.4% in δ18O, respectively.

Sulphur-isotope compositions of pig tissues from a controlled feeding study [PDF]
, 2017 Sulphur-isotope determinations are becoming increasingly useful for palaeodietary reconstruction, but knowledge of isotopic discrimination between diet and various tissues remains inadequate. In this study, we explore the sensitivity of δ34Stissue values

Inhibition of microbial sulfate reduction in a flow-through column system by (per)chlorate treatment. [PDF]
, 2014 Microbial sulfate reduction is a primary cause of oil reservoir souring. Here we show that amendment with chlorate or perchlorate [collectively (per)chlorate] potentially resolves this issue. Triplicate packed columns inoculated with marine sediment were
