Product Description

Thermostable Alpha-Amylase (HS***0) A very robust Alpha-amylase for ethanol productionwith the following benefits:
1.Enhanced liquefaction efficacy;
2.Decreased formation of non-fermentable sugars;
3.Capable to handle various starch materials, such as tapioca, corn, wheat and rice.

DESCRIPTION
HS***0 is a thermostable Alpha-Amylase derived from Bacillus licheniformis. It is an endoamylase that hydrolyzes alpha*1, *-glucosidic bonds to quickly reduce the viscosity of gelatinized starch, producing soluble dextrins and oligosaccharides under various process conditions.

PRODUCT CHARACTERISTICS

Declared Enzyme	Alpha-Amylase
Systematic Name	EC 3.2.1.1, 1, *-alpha-D-glucan glucanohydrolase
Activity	0,*0 U/ml (minimum)
Appearance	Light to dark brown liquid
Product pH	5.5 to 7.0
Specific gravity	1.5 to 1.5 g/ml

EFFECT OF PH
HS***0 is active over a wide pH range depending on the actual applications. For maximum activity, the optimal pH is 6.0 to 6.4. The stable pH range is 5.0 to *0.0 at temperature of *5° C. The exact pH optimum depends on actual processing conditions, such as temperature, substrate concentration and time.

EFFECT OF TEMPERATURE
Optimum temperature of HS***0 for interval liquefaction is above *0° C. It liquefies starch substrates promptly at *5 to *7° C and is till highly active at **0° C. This product demonstrates exceptional thermol stability at temperatures from **5 to **0° C, maintaining its stability for 5 to 7 minutes, keeping on liquefying rapidly and completely. The exact temperature optimum of this product depends on various processing conditions, including pH, substrate concentration and time.

CONCENTRATION OF CALCIUM
The presence of calcium increases the thermal stability of HS***0. It requires a very low calcium concentration and calcium additions of *0 to *0 ppm (dry solid basis) are sufficient to ensure its enzyme stability.

INHIBITORS
Copper, titanium, and cobalt ions are moderate inhibitors for HS***0, whereas aluminum, lead and zinc ions act as strong inhibitors.

USAGE GUIDELINES
In general, first adjust the pH at 6.0 to 6.4 and then add calcium (*0 to *0 ppm dry solids basis) before adding HS***0. Calcium is not necessarily needed when extremely hard water (>*0 German degrees) is used. After the enzyme is added, heat the slurry to liquefy.

DOSAGE
Dosage of HS***0 varies and is dependent on the starch substrate, application, process, substrate concentration, and other factors. To optimize the dosage, it is recommended to conduct a number of liquefaction trials prior to routine use of this product. A good starting point for dosage rate is 0.2 to 0.6kg/TDS.

PACKAGING
HS***0 is packaged in *5kg, *0kg non-hazardous HDPE drums or ***0kg IBC totes. Customized packaging is available upon request.

STORAGE
HS***0 should be stored below *5° C in its original packaging, sealed and unopened, protected from the sun. This enzyme has been formulated for optimal stability. However, enzymes gradually lose activity over time. Extended storage and/or adverse conditions such as higher temperature 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 *5 minutes. For detailed handling information, please refer to the appropriate Material Safety Data Sheet.
