Product Description


Technical Grade Baterial Alpha-Amylase TB-4

for Textile Desizing Industry



A mid-temperature desizing alpha-amylase, especially suitable for cotton, silk and synthetic fabrics.




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.

Declared Enzyme: Alpha-Amylase
Systematic Name: EC, alpha -1, 4–glucan 4-glucanohydrolase
Activity: 4,000 U/ml (minimum)
Appearance: Light to dark brown liquid
Product pH: 5.0 to 7.0
Specific gravity: ≤1.25 g/ml


TB-4 is active at pH ranges from 6.0 to 7.0 with an optimum pH at 6.0. It can be inactivated dramatically at pH below 5.0.

TB-4 is active at temperatures from 30 to 90°C, with an optimum temperature range from 60 to 90°C. At temperatures from 70 to 90°C, the reaction speeds up with the temperature rises while the enzyme inactivation also speeds up.

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.


Copper, titanium and cobalt ions are moderate inhibitors for TB-4, whereas aluminum, lead and zinc ions act as strong inhibitors.
