Product Description
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.
MECHANISM
Pullulanase 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 saccharification and
increase glucose or maltose yield.
