Description

Proteinase From Bacillus Stearothermophilus is a highly thermostable proteolytic enzyme derived from the thermophilic bacterium *Bacillus stearothermophilus*. This robust biocatalyst is valued for its exceptional activity and stability at elevated temperatures and across a broad pH range, making it a critical processing aid in demanding industrial environments. It is essential for manufacturers in the food processing, detergent, leather, and pharmaceutical industries seeking efficient protein hydrolysis and modification.

Application

• Food Processing: Used for protein hydrolysis to produce flavor enhancers (HVP), improve dough handling in baking, and tenderize meat.
• Detergent Formulations: Acts as a key protease additive in laundry and dishwashing detergents for effective breakdown of protein-based stains (e.g., blood, egg, grass).
• Leather Industry: Employed in the dehairing and bating stages of leather production to remove non-collagenous proteins, resulting in softer, higher-quality leather.
• Pharmaceutical & Diagnostic: Utilized in peptide synthesis, diagnostic kit manufacturing, and as a digestive aid enzyme.
• Biofuel & Waste Processing: Aids in the pre-treatment of protein-rich biomass and waste streams to enhance biodegradability and recovery.
• Research & Development: Serves as a model thermostable enzyme in biochemical research and industrial biocatalysis studies.
