Product benefits
Use of HA-350 can bring the following benefits for ethanol production:
1.High stability with low pH;
2.Decrease viscosity quickly;
3.Decrease formation of non-fermenting sugars;
4.No need of calcium ion under majority processing conditions;
5.Effective liquefaction of different starch materials, such as tapioca, corn, wheat and rice.
Description
HA-350 is derived from a strain of Bacillus licheniformis using submerged fermentation and refining extraction techniques. Boli HA-350 is an endoamylase, which rapidly decreases the viscosity of a gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-D-1, 4 glucosidic bonds to produce soluble dextrins and oligosaccharides.
Application
HA-350 is a robust alpha-amylase suitable for ethanol industry.
Product Characteristics
Declared Enzyme
Alpha-Amylase
Systematic Name
1, 4-¦Á -D-glucan glucanohydrolase
Activity
50, 000 U/ml (minimum)
Appearance
Light to dark brown liquid
Product pH
5.5 to 7.0
Specific gravity
1.15 to 1.25 g/ml
Effect of pH
HA-350 is active over a wide pH range, depending on the application. For maximum activity, the optimal pH for Boli HA-350 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-350 is above 85oC. It liquefies starch substrates promptly at 95 to 97oC and maintains highly active at 100oC. For consecutive liquefaction,HA-350 demonstrates exceptional thermo-stability at temperatures up to 105 to 110oC, 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-350. This enzyme requires a very low calcium concentration and calcium additions of 20 to 50 ppm (dry solids basis) are sufficient to ensure enzyme stability.
