Heat-Stable Alpha-Amylase(HA***0)

A low-pH tolerated Alpha-Amylase minimizes production costs with high liquefaction efficacy for fuel ethanol production. It offers the following benefits to ethanol producers: Decreases viscosity quickly, decreases the formation of non-fermenting sugars, effective liquefaction of various starch materials, such as tapioca, corn, wheat and rice, minimum need of calcium ion

DESCRIPTION
HA***0 is derived from a strain of Bacillus licheniformis utilizing a deep fermentation and refining extraction process. HA***0 is an endoamylase, which rapidly decreases the viscosity of a gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the α -D*1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides.

HA***0 is an ideal Alpha-Amylase for the production of ethanol.

CHARATERISTICS:

Declared Enzyme	Alpha-Amylase
Systematic Name	EC 3.2.1.1, 1, *-α -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
HA***0 is active over a wide pH range, depending on the application. For maximum activity, the optimal pH for HA***0 is 5.6 to 6.2. The exact pH optimum will depend on many process variables, including temperature, substrate concentration, and time.

EFFECT OF TEMPERATURE
For interval liquefaction, the optimum temperature of HA***0 is above *5ºC. It liquefies starch substrates promptly at *5 to *7ºC and maintains highly active at **0ºC. For consecutive liquefaction, HA***0 demonstrates exceptional thermo-stability at temperatures from **5 to **0ºC, maintains its stability for 5 to 7 minutes and keeps on liquefying rapidly and completely.

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

INHIBITORS
Copper, titanium, and cobalt ions are moderate inhibitors for HA***0. Aluminum, lead and zinc ions act as strong inhibitors.

DOSAGE
Dosage of HA***0 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 rates is 0.*0~0.*0 kg/TDS.
