Roles of sulfur-containing compounds in fermented beverages with 2-furfurylthiol as a case example

open access: yesFrontiers in Nutrition, 2023
Aroma is a critical component of the flavor and quality of beverages. Among the volatile chemicals responsible for fragrance perception, sulfur compounds are unique odorants due to their extremely low odor threshold.

Sulfur and Sulfur Compounds in Plant Defence [PDF]

open access: yesNatural Product Communications, 2012
The multiplicity of chemical structures of sulfur containing compounds, influenced in part by the element's several oxidation states, directly results in diverse modes of action for sulfur-containing natural products synthesized as secondary metabolites in plants.

Sulfane Sulfur Compounds as Source of Reappearance of Reductive Off-Odors in Wine

open access: yesFermentation, 2022
Reactive compounds with one or more sulfane sulfur atoms can be an important source of reductive off-odors in wine. These substances contain labile sulfur, which can participate in microbiological (enzymatic) and chemical transformations (including in ...

Effects of elemental sulfur and sulfur-bearing minerals on the thermal evolution of aromatic compounds in solid bitumen

open access: yesShiyou shiyan dizhi, 2021
Previous studies have shown that some of the aromatic compound parameters have good correlation with the maturity of organic matter. However, it is still unknown whether the widely used aromatic maturity-related parameters are available with the co ...

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]

open access: yes, 2010
Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

In the Alphaproteobacterium Hyphomicrobium denitrificans SoxR Serves a Sulfane Sulfur-Responsive Repressor of Sulfur Oxidation

open access: yesAntioxidants, 2023
In organisms that use reduced sulfur compounds as alternative or additional electron donors to organic compounds, transcriptional regulation of genes for enzymes involved in sulfur oxidation is needed to adjust metabolic flux to environmental conditions.

Sulfur analysis of Bolu-Mengen lignite before and after microbiological treatment using reductive pyrolysis and gas chromatography/mass spectrometry [PDF]

open access: yes, 2005
Atmospheric pressure-temperature programmed reduction coupled with on-line mass spectrometry (AP-TPR/MS) is used for the first time on microbiologically treated coal samples as a technique to monitor the degree of desulfurization of the various sulfur ...

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

open access: yes, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.
