Alkaline Protease


Habio alkaline protease is produced by bacillus licheniformis with progressive submerged fermentation technology. It can effectively hydrolyze proteins at broad range of temperature and pH conditions, can be applied to many fields such as detergent, leather depilation, leather softening, silk scouring etc..


Activity Definition


One unit (U) of Protease is defined as the quantity of enzyme, which liberates 1μg Forint positive amino acid and peptide of tyrosine per minute at 40°C, pH10.5.

Characteristics

1. Optimum temperature: 40℃-60℃

2. Optimum pH: 8-12

3.Good stability, adapted to different industries

Product Functions

1. Feed industry

Promoting animal’s digestive ability of protein, polypeptide and amino acid; improving animal’s digestive physiological function, reducing diseases. Highly increacing growth, promoting feed utilization rate and reduce costs; it also can be used together with other enzymes.

2. Textile industry


Exclusively hydrolyzing impurities such as keratin, elastin and globulin etc., no damage to collagen, can be used for leather depilation and softening. When soaking it helps leather absorb water, while depilation it helps separate mucoid, which connects fur and skin, thus to loose collagenous fiber and keep leather soft after tanning. For wool fiber processing it plays works well on felting wool, low temperature dyeing, anti-pilling, soft finish and biological polishing;For raw silk degumming makes finished products softly and smoothly, shiny and bright, elasticity, and reduces scathe on the fabric strength, quickly degumming, reduces energy consumption and environment pollutions.

3. Detergent


With wide substrate specificity, good temperature and Ph stability, protease can effectively remove variety protein stains. It’s avaliable for both cold and hot water washing. It will bring better effects if used togerther with lipase and some other enzymes.


4. Alcohol brewing


Effectively decomposing protein macromolecules, improving the output rate of liquor and flavor components concentration; improving the clerification of grape wines and the stability of beer foam; also it can be used other brewing industries such as soy sauce and vinegar brewing; can be used together with beta-glucanase, cellulase etc..


5. Other industries


Effectively hydrolyze protein, can be used in many other industries such as flour processing, gelatin production, meat tenderizing, meet with different processing.
