Thiol Metabolism and Volatile Metabolome of Clostridioides difficile
Frontiers in Microbiology, 2022 Clostridioides difficile (previously Clostridium difficile) causes life-threatening gut infections. The central metabolism of the bacterium is strongly influencing toxin production and consequently the infection progress. In this context, the composition

Vine nitrogen status and volatile thiols and their precursors from plot to transcriptome level. [PDF]
BMC Plant Biol, 2016 Volatile thiols largely contribute to the organoleptic characteristics and typicity of Sauvignon blanc wines. Among this family of odorous compounds, 3-sulfanylhexan-1-ol (3SH) and 4-methyl-4-sulfanylpentan-2-one (4MSP) have a major impact on wine flavor.

Engineering volatile thiol formation in yeast
Journal of Applied Microbiology, 2022 AbstractAimsVolatile thiols are very potent aroma molecules that contribute to the aroma of many beverages. The characteristic thiols of certain wine varieties such as Sauvignon blanc are partly released during the yeast-based fermentation from plant-synthesized glutathione- or cysteine-conjugated and dipeptic precursors present in the must.

Modulation of Welschriesling wine volatiles through the selection of yeast and lactic acid bacteria
OENO One, 2021 Welschriesling is a variety common to Central and Eastern European wine-producing countries; however, its aromatic composition remains poorly understood.

SIMULTANEOUS FLUOROMETRIC MICRODETERMINATION OF HYDROGEN SULPHIDE AND VOLATILE THIOLS IN BEER [PDF]
Journal of the Institute of Brewing, 1974 A fluorometric method is presented for routine simultaneous determination of hydrogen sulphide and volatile thiols. Reproducibility, sensitivity and simplicity were achieved by the procedure described.

Hydrocarbon molar water solubility predicts NMDA vs. GABAA receptor modulation. [PDF]
, 2014 BackgroundMany anesthetics modulate 3-transmembrane (such as NMDA) and 4-transmembrane (such as GABAA) receptors. Clinical and experimental anesthetics exhibiting receptor family specificity often have low water solubility. We hypothesized that the molar

Modulation of Volatile Thiol Release during Fermentation of Red Musts by Wine Yeast [PDF]
Processes, 2022 During the alcoholic fermentation of grape sugars, wine yeast produces a range of secondary metabolites that play a critical role in the aroma profile of wines. One of the most impactful yeast-modified compound families, particularly in white wines, are the ‘fruity’ polyfunctional thiols, which include 3-mercaptohexan-1-ol (3-MH) and 4-mercapto-4 ...
