Glucoamylase is inverting exo-acting starch hydrolases releasing
beta-glucose from the non-reducing ends of starch and related
substrates. The majority of glucoamylases are multidomain enzymes
consisting of a catalytic domain connected to a starch-binding
domain by an O-glycosylated linker region. Three-dimensional
structures have been determined of free and inhibitor complexed
glucoamylases from Aspergillus awamori var. X**0, Aspergillus
niger, and Saccharomycopsis fibuligera. The catalytic domain folds
as a twisted (alpha/alpha)(6)-barrel with a central funnel-shaped
active site, while the starch-binding domain folds as an
antiparallel beta-barrel and has two binding sites for starch or
beta-cyclodextrin.
Glucoamylase Boli GA is made from selected strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. Boli GA has a high conversion rate of starchy substrates into fermentable sugars. It can hydrolyze alpha-D*1,4 glucosidic bonds from the non-reducing end of starch one after. It also hydrolyzes the alpha-D*1,6 glucoside branch bonds of starch and cleaves the alpha*1,3 bonds, releasing glucose. Boli GAhas a robust glucoamylase activity.
Boli GA is widely applied to the production of alcohol, fuel ethanol, glucose, antibiotics and brewing industries. It is used to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca.
This product is available both in solid (powder) and liquid forms.

Effect of PH
For maximum activity, the optimal pH for Boli GA is in the range of 3.5 to 4.5.
Effect of Temperature
The optimal temperature range for Boli GA is *8°C～*5°C(**7°F～**9°F).Temperatures above *5°C (**9°F) can result in loss of activity.
Benefits
Dosage Guidelines
Boli GAis generally added at a level of 0.**2～0.**7% w/w in
ethanol processing (starch, dry solids basis, provided that the
enzyme activity is **0,**0U/ml). The actual dosage depends on the
raw materials, temperature, reaction time, and pH of the
individual plant saccharification/fermentation process, and its
desired result.
