Industrial alkaline protease enzyme for detergent production

Product Description

  Description summary


TTX alkaline protease is a serine endo-proteinase extracted from bacillus licheniformis 2709 using a liquid fermentation technique and refined by an advanced post-treatment technique. It mainly composed by bacillus licheniformis protease, can hydrolysis the macro-molecule protein into free amino acid etc.


It can be widely used in food processing (plant polypeptide extraction, the meats (bone) extractive), medicine raw material extraction, leather and wash profession.






Alkaline   Protease




200,000   U/g

Optimum pH




Valid pH range





Optimum temperature



Loss on drying


Valid temperature range





Six months under 25°C

Particle size

More   than 80% pass through standard sieve of 40 meshes



Definition of content (GB/T23527-2009)

One unit (U) of alkaline protease activity is defined as the amount of enzyme which liberates 1 μg tyrosine per minute from substrate casein at PH 10.5 and 40°C.



  Physico-chemical properties                        




1. A serine endo-proteinase, it can hydrolysis the macro-molecule protein into polypeptide and amino acid.


2.The activity of alkaline protease is activated easily by metal ion Ca2+, Mg2+, Zn2+, Fe2+, it is Insensitive to EDTA, heavy metal and Sulfhydryl Reagents,


3.Activity center includes serine, so the reagent acting on serine e.g sulfonyl halide can make alkaline protease inactivation.



Product Uses


Applications (Adjustable according to experiment results)

1. For leather processing, it can shorten processing time, simplify working procedure and improve product quality. Recommended dosage of 100000 U/g protease is 0.02-0.1%, 20-25°C, 12-20h for retting process; 0.05-0.2%, 35-38°C, 3-6h for leather soften; 0.1-0.3%, 20-35°C, 12-20h for leather depilation.

2. For silk degumming, it may make silk lint-free and fluffy without damaging silk. After pretreatment, the recommended dosage of 100000 U/g protease is 0.8-2.4% pH9-11, 40-50°C, 30-60min.

3. For chondroitin production, it can improve yield and purity, after extracting alkali, recommended dosage of 100000 U/g protease is 0.2-0.6%, pH8-10, 40-50°C, 4-8h.

4. For heparin sodium production, it can increase uniformity of molecule and purity, after salt solution, recommended dosage of 100000 U/g protease is 2-4g per small intestine,pH9-11, 45-60°C, 4-6h.

5. For detergent production, it can remove the stains of sweat, blood, protein and milk, and get a unique detergent effect. Recommended dosage is 0.2-1.0%
