Bacterial Alpha-Amylase TB-0040

 The powerful amylase activity of TB-0040 is capable to break down the starches contained in the textiles into soluble polysaccharides, thus makes it washed out easily. 

DESCRIPTION

Bacterial Alpha-Amylase TB-0040 is a powder enzyme 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-0040 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-0040 is capable to break down the starches contained in the textiles into soluble polysaccharides, thus makes it washed out easily.

 

PRODUCT CHARACTERISTIC

Declared Enzyme:           Alpha-Amylase 

Systematic Name:           EC 3.2.1.1, 1,4-alpha-D-glucan glucanohydrolase 

Activity:                           4,000 U/g(minimum) 

Appearance:                   Beige-yellow powder 

Moisture:                         8%(Maximum)

 

EFFECT OF PH

TB-0040 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.

 

EFFECT OF TEMPERATURE

TB-0040 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.

 

EFFECT OF CALCIUM

Calcium ion plays a protective role for the stability of alpha-amylase activity for TB-0040. Its activity may disappear completely without the presence of calcium ion.

 

INHIBITORS 

Copper, titanium and cobalt ions are moderate inhibitors for TB-0040, whereas aluminum, lead and zinc ions act as strong inhibitors.


APPLICATION AND DOSAGE REFERENCE 

Use of TB-0040 enables easy and efficient desizing without any damage to the fabrics and mild operation conditions without pollution.

 


Note:

1. Protection salts should be added (0.025% CaCl2, 0.4% NaCl2) prior to adding TB-0040.

2. The dosage rate in the above-mentioned table is only for reference. The actual dosage rate should be determined after a numbers of trials according to actual conditions.


PACKAGING

TB-0040 is packaged in 25kg water-proof kraft paper bags or 20kg cardboard drums with plastic bags inside. Customized packaging is available upon request.

 

STORAGE

TB-0040 has been formulated for optimal stability. Typical shelf-life is six months provided being 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 stored properly at 0~10°C. Prolonged storage and/or adverse conditions such as higher temperatures may lead to a higher dosage requirement.

 

SAFETY & ENZYME HANDLING

Inhalation of enzyme dust and mists should be avoided. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the appropriate Material Safety Data Sheet.
