PRODUCT DESCRIPTION
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.
BENEFITS FOR DESIZING
- 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.
EFFECT OF PH, TEMPERATURE & METAL IONS ON ACTIVITY
| 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.
reaction speeds up with the temperature rises while the enzyme inactivation also speeds up. |
Moderate Iinhibitors: Copper, Titanium and Cobalt ions Aluminum, Lead and Zinc ions |
EFFECT OF CALCIUM
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.
