Modulation of volatile sulfur compounds by wine yeast

open access: yesApplied Microbiology and Biotechnology, 2007
Sulfur compounds in wine can be a 'double-edged sword'. On the one hand, certain sulfur-containing volatile compounds such as hydrogen sulfide, imparting a rotten egg-like aroma, can have a negative impact on the perceived quality of the wine, and on the other hand, some sulfur compounds such as 3-mercaptohexanol, imparting fruitiness, can have a ...

Formation of volatile sulfur compounds and metabolism of methionine and other sulfur compounds in fermented food

open access: yesApplied Microbiology and Biotechnology, 2008
The formation of volatile sulfur compounds (VSC) in fermented food is a subject of interest. Such compounds are essential for the aroma of many food products like cheeses or fermented beverages, in which they can play an attractive or a repulsive role, depending on their identity and their concentration. VSC essentially arise from common sulfur-bearing

Selective Determination of Volatile Sulfur Compounds in Wine by Gas Chromatography with Sulfur Chemiluminescence Detection

open access: yesJournal of Agricultural and Food Chemistry, 2010
Volatile sulfur compounds can be formed at various stages during wine production and storage, and some may impart unpleasant "reduced" aromas to wine when present at sensorially significant concentrations.

Volatile Sulfur Compounds Produced by Helicobacter pylori

Journal of Clinical Gastroenterology, 2006
To assess the volatile sulfur compounds produced by three strains of Helicobacter pylori in broth cultures mixed with sulfur-containing amino acids.Halitosis has been reported in H. pylori-positive patients, and volatile sulfur compounds such as hydrogen sulfide and methyl mercaptan are known to be responsible for inducing oral malodor.
