Yeast-Derived Nutrient Matrix for Microbial Fermentation

ART-YD-019 is a non-live yeast derivative formulated as a nutrient matrix for microbial fermentation. The material is typically based on inactivated yeast solids and soluble yeast fractions, providing organic nitrogen and micronutrients without requiring live yeast CFU control. It is suitable for media systems used to propagate bacteria, yeast, and other production microorganisms in agricultural biologicals, enzyme fermentation, starter culture manufacturing, and biotechnology process work.

Typical specification targets may include light tan to brown free-flowing powder, moisture not more than 6.0%, crude protein 45-60%, total nitrogen 7.0-10.5%, amino nitrogen 3.0-6.0%, ash not more than 15%, pH 5.0-7.0 in solution, and 80 mesh pass rate of at least 90%. Solubility is commonly specified at 90-95% depending on grade and process requirement. Because this is an inactivated yeast derivative, it is specified by chemistry, microbiology, and functionality rather than viable CFU/g. Related materials are listed under yeast derivatives for bio applications.

• Agricultural microbial fermentation: biomass propagation for biofertilizer organisms, soil-input cultures, composting accelerators, silage support cultures, and seed-treatment production platforms.
• Industrial biotechnology: organic nitrogen and growth-factor source for bacteria or yeast fermentation where peptone, yeast extract, or autolyzed yeast inputs are evaluated for yield and reproducibility.
• Biopharma process support: raw material candidate for non-clinical development, upstream process optimization, media screening, and scale-up studies that require lot traceability and defined documentation.
• R&D and pilot plants: practical 20 kg sack format for media trials, pilot fermenters, and transition from bench formulation to purchasing-controlled supply.
• Custom specification work: procurement teams may request tighter limits for moisture, total plate count, heavy metals, particle size, or amino nitrogen when project volumes justify a controlled supply program.

Store unopened sacks in a clean, dry warehouse at 10-25 °C and below 65% relative humidity. Keep away from standing water, direct sunlight, high heat, and strong odors. The recommended shelf life is typically 24 months from manufacture when stored in the original sealed 20 kg multi-wall sack. After opening, reseal promptly and use FIFO inventory controls to limit moisture pickup. For media preparation, disperse with moderate agitation; heat sterilization or filtration should be selected according to the final process design and microbial sensitivity.

ArtemisYeast supplies ART-YD-019 for inquiry-based industrial purchasing, with batch documentation available for qualification review. A standard document set can include Certificate of Analysis, technical data sheet, safety data sheet, allergen statement, country-of-origin statement, GMO-status statement where applicable, and food or feed suitability declaration when relevant to the selected grade. Testing parameters may cover moisture, protein or nitrogen, amino nitrogen, ash, pH, particle size, total plate count, yeast and mold, coliforms, heavy metals, and identity checks.

Manufacturing and supplier controls are managed through HACCP-aligned quality systems, and ISO 22000, FSSC 22000, Halal, or Kosher documentation can be reviewed on request when applicable to the production site and lot.
