Lallemand boulardii

S. boulardii production

Expert in yeast production since 1923

Pioneer in the probiotic industry, expert in yeast development and production for almost 100 years, Lallemand offers the well-known and unique probiotic yeast Saccharomyces boulardii reaching the highest quality standards. Find out the manufacturing process of S. boulardii by Lallemand:


Identity validation

Lallemand Saccharomyces boulardii strain, a Saccharomyces cerevisiae species variant, has been registered as Saccharomyces boulardii CNCM I-1079 at the Collection Nationale de Cultures de Microorganismes. Managing each step of the yeast manufacturing process, Lallemand ensures the production of an optimized and high quality yeast:

  • Entire genome is sequenced and annotated
  • Proteomic profile is checked
  • DNA fingerprinting analysis is performed before the release of all batches


Probiotic viability assurance

[Tompkins, 2011] – Survival through the gut

Lallemand demonstrated the survival of its strain S. boulardii CNCMI I-1079 through the upper gastrointestinal tract thanks to an in vitro Digestive System (IViDiS) model reproducing environmental conditions of human upper intestinal tract.

  • S. boulardii survives in the upper gastrointestinal tract.
  • S. boulardii can be consumed at anytime.
  • “The yeast survival was independent of the meal or beverage consumed” – Dr. Thomas Tompkins.
