Description

Thermostable Alpha-Amylase Highlights

A very robust Alpha-amylase with exceptional thermostability. Ideal for medium-temperature cooking process in fuel ethanol production:

    Enhanced liquefaction efficacy
    Decreased formation of non-fermentable sugars
    Fits to various starch materials, e.g. tapioca, corn, wheat and rice

Thermostable Alpha-Amylase Description

Boli HS***0 is a thermostable Alpha-Amylase derived from a modified strain of 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.

Thermostable Alpha-Amylase Characteristics
Declared Enzyme: Alpha-Amylase
Systematic Name: EC 3.2.1.1, 1,*-alpha-D-glucan glucanohydrolase
Activity: *7,**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

Thermostable Alpha-Amylase Effect Of PH

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

Thermostable Alpha-Amylase Effect Of Temperature

Optimum temperature of Boli HS***0 for interval liquefaction is above *0°C. It liquefies starch substrates promptly at *5 ~ **0°C. Boli HS***0 demonstrates exceptional thermal stability at temperatures up to **5 ~ **0°C, maintains its stability for 5 ~7 minutes and keeps on liquefying rapidly. The exact temperature optimum of this product depends on the actual processing conditions, including pH, substrate concentration and processing time.

Thermostable Alpha-Amylase Concentration Of Calcium

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

Thermostable Alpha-Amylase Inhibitors

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

Thermostable Alpha-Amylase Usage Guidelines

    Step 1. Adjust pH to 6.0 ~ 6.4
    Step 2. Add calcium (*0 ~ *0 ppm dry solid basis) *
    Step 3. Add Boli HS***0**
    Step 4. Spary the slurry at **5 ~ **0ºC for 5 minutes
    Step 5. Lower the temperature to *0 ~ **0ºC and keep for **0 minutes

Note:

    Calcium is not needed when extremely hard water (above *0 German degrees) is used.
Actual dosage of Boli HS***0 depends 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 is 0.4 ~ 0.6 kg/TDS.
