Yeast Extract for Microbial Fermentation

ART-MN-026 is a fermentation-grade yeast extract designed for microbial nutrition programs where lot consistency, solubility, and traceable documentation are procurement priorities. It is produced from food-grade yeast biomass through controlled autolysis and concentration, then dried to a free-flowing powder. The ingredient supplies peptides, free amino acids, B-complex vitamins, minerals, nucleotides, and other low-molecular-weight yeast solids that support reproducible growth and metabolite formation in industrial fermentation media.

Typical specification targets include moisture not more than 6.0%, total nitrogen 9.0-12.0%, amino nitrogen 4.0-7.0%, sodium chloride not more than 6.0%, ash 8.0-15.0%, pH 5.0-7.0 in a 2% solution, and high water solubility with low insoluble residue. Particle size is typically fine powder, often 80 mesh pass, suitable for dry blending or direct media make-up. For related media inputs, see microbial nutrition and fermentation ingredients.

• Industrial microbial fermentation: organic acids, amino acids, enzymes for processing, polysaccharides, starter cultures, and specialty metabolites where complex nitrogen improves biomass formation.
• Biopharma upstream and recombinant systems: non-animal-origin nutrient input for microbial expression platforms, subject to customer qualification, internal validation, and process suitability testing.
• Food and beverage fermentation: nutrient addition for selected starter culture propagation, vinegar, savory fermentation, and fermentation-derived flavor precursor systems.
• R&D scale-up: bench, pilot, and production media optimization where scientists compare yeast extract nitrogen level, amino nitrogen, ash, and color between lots.
• Contract manufacturing: standardized bulk sack format for plants requiring palletized inbound materials, lot-specific CoA, and repeatable supply planning. To initiate specification matching, use request a bulk quote.

Store ART-MN-026 in the original sealed 20 kg multi-wall sack in a clean, dry, odor-free warehouse at ambient temperature, ideally below 25°C and away from direct sunlight, steam lines, and high humidity. Keep bags closed after sampling to protect the powder from moisture uptake and caking. Typical shelf life is 24 months from manufacture when stored under recommended conditions.

For media preparation, add slowly under agitation to warm or ambient purified water, then complete dissolution before pH adjustment and sterilization. Validate heat treatment, filtration, and compatibility with salts, carbohydrates, antifoams, and trace-element solutions in the customer process.

ArtemisYeast supplies ART-MN-026 for industrial buyers that require clear lot traceability, consistent analytical data, and export-ready paperwork. Standard documents may include Certificate of Analysis, product specification, allergen statement, non-animal-origin declaration, safety data sheet, and food-grade declaration where applicable. HACCP-aligned manufacturing information and available ISO 22000, FSSC 22000, Halal, or Kosher documentation can be reviewed on request depending on production site and lot.

Routine test parameters may cover appearance, odor, moisture, total nitrogen, amino nitrogen, ash, sodium chloride, pH, solubility, heavy metals, total plate count, yeast and mold, coliforms, and absence of specified pathogens. ArtemisYeast can support supplier qualification, sample approval, and recurring shipment planning. Review our documentation approach at quality and compliance.
