In wines, the presence of sulfur compounds is the resulting of several contributions among which yeast metabolism. The characterization of the starter Saccharomyces cerevisiae needs to be performed also taking into account this ability even if evaluated together with the overall metabolic profile. In this perspective, principal aim of this experimental research was the evaluation of the volatil...

We tested selected, potential repellents in pen and field trials to determine their ability to reduce consumption of palatable foods by pocket gophers (Zbmomys talpoides), deer (Odocoileus spp.), and elk (Cewus elqhus). Only sulfur-based compounds (predator urines and Deer AwayB) deterred feeding by captive gophers. Chemically hot, bitter, and noxious compounds and plants did not deter gopher f...

Mass-independent fractionation of sulfur isotopes (S MIF) in Archean and Paleoproterozoic rocks provides strong evidence for an anoxic atmosphere before ~2,400 Ma. However, the origin of this isotopic anomaly remains unclear, as does the identity of the molecules that carried it from the atmosphere to Earth's surface. Irrespective of the origin of S MIF, processes in the biogeochemical sulfur c...

Those chemically defined media which have been proposed for cultivation of Brucella vary widely, both qualitatively and quantitatively, with respect to their content of sulfur compounds (McCullough and Dick, 1943; McCullough et al., 1947; Gerhardt and Wilson, 1948; Rode, Oglesby, and Schuhardt, 1950). Since the early studies of Zobell and Meyer (1932) there has been no critical investigation of...

Addition of dimethylsulfide (DMS), dimethyldisulfide (DMDS), or methane thiol (MSH) to a diversity of anoxic aquatic sediments (e.g., fresh water, estuarine, alkaline/hypersaline) stimulated methane production. The yield of methane recovered from DMS was often 52 to 63%, although high concentrations of DMS (as well as MSH and DMDS) inhibited methanogenesis in some types of sediments. Production...

Photocatalytic oxidation of the sulfur-containing compounds, trimethylene sulfide (C3H6S), propylene sulfide (C3H6S), thiophene (C4H4S), and methyl disulfide (C2H6S2), was carried out using an annular plug flow reactor with TiO2 in a supported form. Formation of products and byproducts was monitored in real time using a mass spectrometry online system. Mineralization of the sulfur-containing co...
