Alpha-amylase TH-2 (Thermostable)

A high temperature desizing alpha-amylase, enables desizing rate reach 90 to 95%, enables desizing and colour-fixing at the same bath, thus save energy, processing time and costs.

DESCRIPTION

Heat-stable Alpha-Amylase TH-2 is produced from selected strains of Bacillus licheniformis through submerged and refining extraction process. It is an endoamylase that can efficiently decrease 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 oligosaccharide s under high temperature and low pH conditions.


Alpha-Amylase TH-2 has superior thermal stability and a wide range of pH tolerant. It is especially suitable for the desizing

of textiles such as cotton, silk, polyvinyl alcohol fibers, rayon fibers, blended fabrics, dyed poplin, etc.


PRODUCT CHARACTERISTICS

Declared Enzyme:             Alpha-Amylase

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

Activity:                             20,000 U/ml (minimum)

Appearance:                     Sepia brown liquid

Product pH:                       5.8 to 6.8

Specific gravity:                 1.10 to1.25 g/ml


EFFECT OF PH

TH-2 is active over a wide pH range, depending on the application conditions. The optimal pH is 5.4 to 6.4.


EFFECT OF TEMPERATURE 

Optimum temperature of TH-2 for interval liquefaction is above 77ºC. It liquefies starch substrates promptly at 85 to 90ºC and demonstrates exceptional thermal stability at 100ºC. The exact temperature optimum depends on actual processing conditions, such as pH, concentration of substrate, processing time, etc.


CONCENTRATION OF CALCIUM

The presence of calcium plays a protective role for the thermal stability of this enzyme. TH-2 requires a very low calcium concentration, i.e. 5 to 20 ppm will be sufficient to ensure its thermal stability.



INHIBITORS

Copper, titanium, and cobalt ions are moderate inhibitors for TH-2, whereas aluminum, lead and zinc ions act as strong inhibitors.
