Yeast Extract for Fermentation

ART-MN-009 is a spray-dried yeast extract designed for fermentation media where consistent nutrient contribution, fast dispersion, and low insoluble matter are required. It is produced from food-grade yeast biomass by controlled autolysis or hydrolysis, then clarified, concentrated, and dried to a free-flowing powder. The product contributes amino nitrogen, peptides, nucleotides, B-group vitamins, minerals, and growth factors that support robust biomass formation and metabolite production in industrial microbial systems.

Typical specification targets include moisture ≤6.0%, crude protein 60–70% on dry basis, total nitrogen 9–12%, amino nitrogen 3–6%, ash 8–15%, pH 5.0–7.0 in solution, and high water solubility with low sediment after dissolution. Particle size is commonly fine powder, about 60–80 mesh, suitable for dry blending or direct tank addition. Actual values are confirmed by certificate of analysis for each lot. For related media inputs, review the microbial nutrition and fermentation category.

• Microbial fermentation: organic nitrogen and micronutrient source for bacteria, yeast, and filamentous fungi used in enzyme production, amino acid fermentation, organic acid production, starter culture manufacture, and specialty ingredient fermentation.
• Biopharma upstream process development: nutrient component for non-animal-origin media strategies, seed train optimization, microbial expression systems, and cell culture media where a complex yeast-derived hydrolysate is specified by the buyer’s formulation team.
• R&D to plant scale transfer: supports screening of yeast extract concentration, nitrogen balance, C:N ratio, dissolved oxygen demand, pH control behavior, foam tendency, and sterilization compatibility before larger scale procurement.
• Media premix manufacturing: suitable for dry premixes when combined with peptones, sugars, salts, buffers, antifoam carriers, or trace nutrient blends, subject to buyer validation for flowability and segregation.
• Procurement programs: supplied as 20 kg multi-wall sacks for palletized orders, repeat lots, and export shipments. For allocation, documentation, and lead time confirmation, use the bulk quote on request workflow.

Store unopened sacks in a cool, dry, well-ventilated warehouse, protected from direct sunlight, condensation, strong odors, and floor moisture. Recommended storage is below 25°C with relative humidity controlled where possible. Under recommended conditions, typical shelf life is 24 months from manufacture; the lot label and CoA govern the exact date.

After opening, reseal promptly or transfer to a clean, dry, closed container. Avoid inhalation of dust during charging and use local extraction or appropriate plant PPE according to site procedures. The powder disperses readily in water; for sterile media, validate heat treatment or filtration strategy against your process requirements.

ArtemisYeast supplies ART-MN-009 for industrial B2B use with lot-based traceability and specification review before shipment. Available documentation may include certificate of analysis, product specification, allergen statement, non-animal-origin statement where applicable, material safety data sheet, and food-grade declaration. HACCP-aligned manufacturing information and ISO 22000, FSSC 22000, Halal, or Kosher documentation can be requested when supported by the producing site and selected lot.

Routine quality checks typically cover appearance, odor, moisture, nitrogen profile, pH, ash, solubility, heavy metals, and microbiological limits such as total plate count, yeast and mold, coliforms, and specified pathogens. Buyers running regulated or high-sensitivity fermentation should request pre-shipment documentation and approve test methods in writing.
