What Is Saccharomyces Cerevisiae

Saccharomyces cerevisiae is a species of fungus that is a yeast. It is a crucial component of winemaking, baking, and brewing, and has been for a long time. It has been studied more than almost every other microorganism.

History of Saccharomyces Cerevisiae

This fungus was used extensively in the 1800s by bread bakers, who obtained yeast from beer brewers. Thanks to advances in a refining process patented by Louis Pasteur, a very pure version of the fungus was able to be isolated. Centrifuges were used for concentrating it, making the commercial production of it possible. This fungus has become widely used by bakers in the US and abroad. It has become the standard yeast for bread bakers from the 20th century onward.

Symptoms of Diseases Caused By Saccharomyces Cerevisiae

Saccharomyces cerevisiae has been found to be an opportunistic human pathogen. However, it has relatively low virulence, meaning humans are not at a high risk of becoming infected. Direct contact with this fungus rarely leads to an infection. When it does infect humans, it is found in the skin, mouth, vagina, and digestive tract.

Women are most likely to suffer from infection, mainly if they have been sexually active with bakers. However, cases are very rare, with no case reported since 1999. In some cases, the use of yeast in home baking leads to infection.

Invasive infections are possible, albeit rarely. This is when the fungus enters the bloodstream in some way. This can become life-threatening. Over 30% of cases lead to death, even if treatment is conducted. People who have been weakened by cancer or other severe illnesses will also have a higher level of risk.

Common symptoms include:

  • Chills
  • Fever
  • Inflammation
  • Facial pain
  • Swelling

How You Can Treat Saccharomyces Cerevisiae

To get proper treatment for Saccharomyces cerevisiae, you can follow the similar guidelines for treating other types of ingesting fungus.

One option you can talk to your doctor about involves taking antifungal medication. Additionally, you can receive multiple allergy shots over a few years. It is a very effective method that is helpful for some mold allergies.


Preventing a Saccharomyces cerevisiae fungal infection in the first place requires you to avoid eating old and moldy bread. Additionally, avoid inhaling yeast involved in the baking of bread or the making of beer.


Since fungal infections can spread throughout the body and compromise the immune system, a cure may involve taking antifungal drugs to ensure breathing and circulation are improved. Treating the underlying symptoms helps effectively curing yourself of a fungal infection brought on by Saccharomyces cerevisiae. This fungus is more infectious than others, making speed in treatment essential to be cured.
