Pullulanase PU-700 is produced from Bacillus Licheniformis strain through flocculation and purification. This enzyme is used to hydrolyze Pullulan (a polymer chain of maltotriose linked together via α-1,6 glycosidic bond). PU-700 can effectively cleave the α-1,6 glycosidic bond of amylopectin, and then cleave the entire branch structure to produce amylose.
Effect of pH on Pu-700: PU-700 works in the pH range of 4.0 ~ 5.0 depending on different applications. The optimum pH of PU-700 is 4.2 ~ 4.6.
Effect of temperature on Pu-700: The effective operating temperature of PU-700 is from 50 to 65°C and the optimum temperature range is from 55 to 65°C.
Recommended dosage: 110 – 1880 gr/ton of raw material.
Inactivate enzymes: To inactivate PU-700, increase the temperature above 80oC and hold for 30 minutes.
Packing: 30kg HDPE drum.
Expiry date and storage: The product should be stored below 25°C, away from direct sunlight. At this temperature the product has a shelf life of 6 months. If stored properly at 0 – 10°C, the product has a shelf life of 18 months.
