Identification

NameSulfite
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionA sulfite (SO32-) is a salt of sulfurous acid (H2SO3). Sulfite is an intermediate in the sulfate reduction (assimilatory) pathway which reduces sulfate to hydrogen sulfide, the required form for sulfur assimilation into biosynthetic pathways. Sulfites occur naturally in a number of foods and beverages and in all wines to some extent. Sulfites are commonly introduced to arrest fermentation at a desired time, and may also be added to wine as preservatives to prevent spoilage and oxidation at several stages of the winemaking.
