Pullulanase PU-720 is produced from Bacillus licheniformis through submerged fermentation, extraction and refining processes. It is so-named because it can specifically hydrolyze pullulan (maltotriose, α-1, 6 glycosidic bond linking polymer). It belongs to amylase which specifically cleaves the α-1, 6 glycosidic bonds of the branching point of amylopectin and cut the entire branch structure to form amylose.
PU-720 is typically used in combination with glucoamylase to produce high glucose syrup and high maltose syrup from liquefied starch.
PRODUCT APPLICATIONS AND BENEFITS
- In the production of beer, if the starch is not completely decomposed, the fermentable sugar content will be decreased, and the beer made from fermentation will not meet the requirements.
- The synergistic effect of pullulanase with alpha-amylase will enable pullulanase to completely decompose starch contained in the raw materials, reduce the wort content in the beta-limit dextrin, increase the amount of fermentable sugar, thus greatly improve the fermentation efficacy.
EFFECT OF PH
The effective pH range for PU-720 is from 4.0 to 5.0; its optimum pH ranges from 4.2 to 4.6.
EFFECT OF TEMPERATURE
PU-720 works effectively at temperatures from 50 to 65°C; its optimum temperature range is from 55 to 60°C.
