Isotopic Fractionation of Sulfur in Carbonyl Sulfide by Carbonyl Sulfide Hydrolase of Thiobacillus thioparus THI115
Carbonyl sulfide (COS) is one of the major sources of stratospheric sulfate aerosols, which affect the global radiation balance and ozone depletion. COS-degrading microorganisms are ubiquitous in soil and important for the global flux of COS. We examined the sulfur isotopic fractionation during the enzymatic degradation of COS by carbonyl sulfide hydrolase (COSase) from Thiobacillus thioparus T...
متن کاملPlant Uptake of Atmospheric Carbonyl Sulfide in Coast Redwood Forests
The future resilience of coast redwoods (Sequoia sempervirens) is now of critical concern due to the detection of a 33% decline in California coastal fog over the 20th century. However, ecosystem-scale measurements of photosynthesis and stomatal conductance are challenging in coast redwood forests, making it difficult to anticipate the impacts of future changes in fog. To address this methodolo...
متن کاملSources And Cycling of Carbonyl Sulfide in the Sargasso Sea
The cycling of the radiatively important gas carbonyl sulfide (OCS) was studied in surface waters of the Sargasso Sea. In August 1999, surface OCS concentrations averaged 8.6 pmol L21, showed minor diel variations, and varied little with depth. An OCS precursor, total dissolved organic sulfur (DOS), was lowest at the surface (40 nmol L21) and increased with depth. The photoproduction rate of OC...
متن کاملSulfide intrusion in seagrasses assessed by stable sulfur isotopes—a synthesis of current results
*Correspondence: Marianne Holmer, Department of Biology, University of Southern Denmark, Campusvej 55, DK-5230 Odense M, Denmark e-mail: [email protected] Sulfide intrusion in seagrasses, as assessed by stable sulfur isotope signals, is widespread in all climate zones, where seagrasses are growing. Seagrasses can incorporate substantial amounts of 34S-depleted sulfide into their tissues wit...
متن کاملSulfide invasion in the seagrass Posidonia oceanica at Mediterranean fish farms: assessment using stable sulfur isotopes
The effect of organic enrichment of sediments on the composition of stable sulfur isotopes (δ34S), sulfide invasion (Fsulfide) and concentrations of total sulfur (TS) and elemental sulfur (S0) in the seagrass Posidonia oceanica was investigated along transects from 3 Mediterranean fish farms in Spain, Italy and Greece. The δ34S decreased and Fsulfide, TS and S0 decreased with distance from the ...
