Fermentation Ingredients

Microbial growth requires a culture media that contains essential nutrients such as:

  • a carbon source
  • nitrogen in the form of peptides and amino acids
  • vitamins and minerals
  • other less well defined components commonly known as undefined growth factors


Lallemand’s Fermentation Nutrient Ingredients (FNI) provide yeast extract, yeast peptones and yeast autolysates required as constituent of bacteriological media and culture media for the growth of many microorganisms. FNI perform not only as “bug boosters,” but they also have a positive effect on:

  • stability of large culture formulation
  • acidification performance
  • sporulation rate
  • metabolites production and proteins expression


Lallemand’s Fermentation Nutrient Ingredients (FNI) can improve fermentation performance for a broad range of industries such as food industries, biopharmaceutical and bioremediation.


Our yeast peptone and yeast autolysates product range varies in B-vitamins, nucleotides, minerals, and alpha-amino nitrogen content, in their active and natural forms. Products are available in powder, agglomerated powder and liquid form.
