Description

Neutral Protease

Characteristics and Applications:
The Neutral Protease is a solid enzyme derived from Bacillus Subtilis fermentation. Neutral Protease can hydrolyze the protein into soluble peptides. It can be applied to leather molting and softening, silk de-gumming, film silver recovery, as well as in medicine industry.

Definition of activity:
1 unit equals the amount of enzyme which produces 1.0 ug tyrosin hydrolyzed by 1.0 g solid enzyme of Neutral Protease at *0, pH7.5 in 1minute, and sign as u/g.

Specification & Package:
Neutral Protease is produced in powder form with water content less then 8%. The product is available in *0kg or *0 kg sacks containing 2kg plastic bags. The production activity of more than *0,**0 unit/g

Standard:
Industrial Standard QB******3 of the Peoples Republic of China

Optimal temperature:
****5 Optimal PH6.**7.5

Application:
1. Leather molting: molting used enzyme (****2, PH7.5, ****5u/ml) →washing the leather→ soaking the leather in acid liquid→ tanning
2. Film silver recovery: *5 pH 7.**7.5 Recovered by ****3u/ml
3. Silk de-gumming: pretreatment→ dehydration→ treating with acid liquid(Protease****4u/ml, soap 0.*5%, ****0, ****0min, pH**8)→ dehydration→de-gumming→ washing→ dehydration→ fluffing→ drying→ fluffing
4. Medicine industry: ***8 Neutral Protease has capability to disintegrate poly-saccachride, it can wipe off phlegm. It can be applied to treat Chronic bronchitis,Bronchiectasis,Cough and so on. The products have a good effect on adhesion, decrustation, thrombophlebitis.
5. Forage Enzyme: a compound enzyme mixed by neutral protease, α-amylase, Acid protease, Cellulase, Glucoamylase. These products can be wildly used in feeding suckling pig, grown pig, poultry and fish. After adding forge enzyme into the feedstuff, materiel can be decomposed to small unit through controlling temperature , humidity and pH. In the smalls scale breeding, forge enzyme can be directly mixed with the feedstuff, which should equably distribute in the feedstuff. The dosage is 0.*1.0% of the feedstuff.

Storage and transportation:
The products should be kept dry and cold, keep away from light. Avoid sunshine and drenching in the transportation. When stored at *5,the product will retain *5% of its activity for 6 month.
