Industial alpha amylase for fuel ethanol, bioethanol enzyme
Company Information
Jiangsu Boli Bioproducts Co., Ltd.is a professional manufacturer of quality and cost-effective enzymes that bring added-value to our customers. With more than twenty years expertise in enzyme research and development, Boli Bioproducts has been recognized as a reliable partner that helps to improve their bottom-line because of consistent high quality, competitive price and unparalleled excellent services.
The history ofBoli Bioproducts can be traced back to 1998, when its co-founders started with an enzyme consulting company specialized in enzyme design and commercialization in response to the specific needs of its customers. With the rapid growth of enzyme industry in China, in order to better serve customers, its co-founders set up a world-class production facility in 2005 in Jiangyan Economic Development Zone (about 230 km northwest to Shanghai), Jiangsu Province. The plant covers an area of approximately 20,000 m2, with annual enzyme production capacity of 30,000 MT.
Boli Bioproducts's enzyme products can be divided into industrial grade and food grade, and are available in both liquid and solid (powder) forms. Among the many varied applications for these enzymes are: fuel ethanol production, grain processing, food baking, brewing, textiles andanimal feed. Our top products such asGlucoamylase, Alpha Amylase, Beta-Glucanase, Catalsae and Protease are widely accepted and highly appreciated by our customers because of the benefits --- higher enzyme activity, superior pH and thermal stability, greater starch-ethanol conversion rate, less enzyme dosage, less emission of waste, easier processing, more output --- that are greatly helpful to improve their bottom line.
Product Description
Product highlights
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:
1. Decreases viscosity quickly
2. Decreases the formation of non-fermenting sugars
3. Effective liquefaction of various starch materials, such as tapioca, corn, wheat and rice, minimum need of calcium ion.
4. Effective liquefaction at low pH
Description HA-320 is derived from a strain of Bacillus licheniformis utilizing a deep fermentation and refining extraction process. HA-320 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.
Application HA-320 is an ideal Alpha-Amylase for the production of ethanol. Product Characteristics

Effect of pH HA-320 is active over a wide pH range, depending on the application. For maximum activity, the optimal pH for HA-320 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-320 is above 85ºC. It liquefies starch substrates promptly at 95 to 97ºC and maintains highly active at 100ºC. For consecutive liquefaction, HA-320 demonstrates exceptional thermo-stability at temperatures from 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-320. This enzyme requires a very low calcium concentration and calcium additions of 20~50 ppm (dry solid basis) are sufficient to ensure enzyme stability. Inhibitors Copper, titanium, and cobalt ions are moderate inhibitors for HA-320. Aluminum, lead and zinc ions act as strong inhibitors.
Dosage Dosage of HA-320 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 0.40~0.80 kg/TDS.
