Clostridium butyricum

The most critical factor is the viable count (CFU/g), which typically ranges from 1x10^8 to 1x10^11 CFU/g. Buyers must also verify the spore formation rate, as a higher rate ensures better stability and resistance to gastric acid and high temperatures during feed processing or storage. Additionally, ensure the product is free from pathogenic contamination such as Salmonella and E. coli.

For agricultural and feed additives, suppliers should hold ISO 9001 and ISO 22000 (FSMS) certifications. If the product is intended for the EU market, FAMI-QS (Feed Additives and Pre-mixtures Quality System) is essential. For the US market, ensure the strain is FDA-GRAS (Generally Recognized as Safe) or compliant with AAFCO guidelines. Always request a Certificate of Analysis (COA) for every batch.

High-quality Clostridium Butyricum is produced using liquid deep fermentation followed by vacuum freeze-drying or spray drying with protective agents. These technologies ensure a long shelf life (usually 12-24 months) and maintain the biological activity of the bacteria. Ask suppliers about their encapsulation technology, which can further protect the bacteria from environmental stressors.

It is primarily used as a probiotic feed additive for livestock (swine, poultry) and aquaculture to improve gut health, enhance immunity, and replace antibiotic growth promoters (AGPs). It is also used in pharmaceutical grade for human probiotic supplements and in environmental bioremediation to treat organic waste.

Always request a pre-shipment sample for third-party lab testing to verify the active cell count. Use Made-in-China.com's Secured Trading services to ensure payment is only released after the quality meets the agreed-upon specifications. Avoid suppliers who cannot provide a stability test report.

While Clostridium Butyricum spores are relatively heat-resistant, it is best to ship in cool, dry conditions (below 25°C). For long-distance sea freight, specify reefer containers if purchasing high-activity concentrates. Ensure the packaging is vacuum-sealed and moisture-proof using multi-layer aluminum foil bags to prevent oxidation.

Pricing is highly sensitive to the CFU concentration. Negotiate based on the price per billion CFU rather than just the price per kilogram. For new buyers, suggest a tiered pricing structure where the price drops by 10-20% for orders exceeding 500kg, and request a low MOQ for the first trial order to validate market response.

Microbial products often require an Import Permit for Biological Species in many countries. Ensure the supplier provides a clear Material Safety Data Sheet (MSDS) and a Non-GMO Declaration if required. Check if your local customs require a Veterinary Health Certificate for feed-grade microbial imports.
