Import Alkaline Protease — Buy in wholesale FOB from Supplier in China

Zibo Green Trade Co., Ltd. supplies Alkaline Protease as a liquid concentrate produced through deep liquid fermentation of Bacillus subtilis, a well-characterised GRAS-host organism for industrial enzyme production. This preparation is concentrated and refined post-fermentation for direct use or dilution in downstream applications. The liquid form offers advantages for automated dosing and rapid dispersion in aqueous process media. The supplier identifies leather tanning, animal feed, bakery, condiments, beer brewing, soy sauce manufacture, and detergent formulation as target sectors, indicating broad pH and temperature tolerance for alkaline hydrolysis operations.

Liquid alkaline protease concentrates typically contain 15% to 30% active enzyme protein by weight, balanced with stabilisers such as propylene glycol, sorbitol, or sodium chloride to prevent microbial growth and maintain solubility. The exact activity concentration, expressed in U/mL or AU/mL, is not stated in the source data and must be confirmed directly. Bacillus subtilis alkaline protease (subtilisin) operates effectively from pH 8 to 11, with optimal activity near pH 10, though formulation with calcium ions may shift or broaden this profile. The liquid concentrate form eliminates dust exposure risks associated with powdered or granule enzymes, reducing respiratory protection requirements and clean-room burden in handling areas.

Buyers span leather tanners seeking bating and softening, feed compounders processing protein meals, fermenters in brewing and soy sauce production, and detergent manufacturers. The supplier notes export suitability for B2B procurement, though specific packaging configurations, MOQs, and lead times are not provided. Liquid concentrates require temperature-controlled storage, typically 0 to 10 degrees C for extended stability, with protection from freeze-thaw cycles that can precipitate protein and reduce activity. Zibo Green Trade Co., Ltd. holds a harbor trust tier with no recorded response history, necessitating proactive direct engagement to secure specifications, samples, and contractual terms before committing to volume orders.

Zibo Green Trade Co., Ltd. is located at Zibo Zhoucun Textile Science And Technology Five West 18, Binzhou, China, a location within Shandong Province's chemical and textile industrial corridor. The supplier carries a harbor trust tier with zero recorded response rate and zero average response hours. No information is provided about manufacturing ownership, in-house fermentation capacity, toll manufacturing arrangements, or quality management certifications. Buyers should treat the company as a trading entity until verification of production credentials is obtained.

The listing emphasises deep liquid fermentation and extract refinement capabilities, suggesting either direct manufacturing or close technical partnership with a fermentation facility. The broad application claims across food and non-food sectors imply either multiple product grades or a single technical-grade material with buyer-beware responsibility for end-use suitability. Prospective purchasers should request facility audit reports, fermentation capacity data, batch consistency records, and regulatory compliance documentation relevant to their specific industry before relying on supply commitments.
