Bacterial Alpha-Amylase TB-4 is produced from strains of Bacillus subtilis through submerged fermentation, extraction and refining process. It can rapidly decreases the viscosity of the gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-1, 4 glycosidic bonds and produces soluble dextrins and oligosaccharides.


  • Alpha-Amylase TB-4 is suitable for desizing of textiles sized by starchy materials, particularly fits to those textiles that are not heat resistance, such as cotton, silk, synthetic fabrics.
  • The powerful amylase activity of TB-4 is capable to break down the starches contained in the textiles into soluble polysaccharides, thus makes it washed out easily.
  • Use of TB-4 enables easy and efficient desizing without any damage to the fabrics and mild operational conditions without any pollution.




pH Temperature Metal Ions

 Active at pH ranges from 6.0 ~ 7.0

 Optimum pH is 6.0.


 TB-4 can be inactivated dramatically at

 pH below 5.0.

 TB-4 is active at 30 ~ 90°C.


 Optimum temperature 60 ~ 90°C.

 At temperatures from 70 to 90°C, the

 reaction speeds up with the  temperature rises while the enzyme

 inactivation also speeds up.

 Moderate Iinhibitors:

 Copper, Titanium and Cobalt  ions

 Strong inhibitors:

 Aluminum, Lead and Zinc  ions

Calcium ion plays a protective role for the stability of alpha-amylase activity for TB-4. Its activity may disappear completely without the presence of calcium ion.

Shelf-life  &


  • Typical shelf-life is six months if it is stored below 25°C in its original packaging, sealed and unopened, protected from the sunlight.
  • Its shelf-life will be eighteen-months if this product is being store properly at 0∼10°C.
  • Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement, thus should be avoided.
