    PRODUCT DESCRIPTION This product is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation. It is a thermal stable debranching enzyme able to work at low pH, and is widely used in brewing, starch sugar processing, monosodium glutamate and alcohol fermentation, etc.MECHANISMPullulanase is a type of isoamylase which can selectively hydrolyze α-1,6-glucosidic linkage in pullulan, starch and oligosaccharides, thereby, making the complete hydrolysis of branched starch possible. Together with other enzymes (glucoamylase, β-Amylase) it speeds up saccharificat...

Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
