Glucoamylase

Glucoamylase Highlights

An outstanding glucoamyalse particularly ideal for fuel ethanol production:

• Very thermostable
• Robust glucoamylase activity
• Faster fermentation
• More ethanol output
• Less starch residues
• Fits to various materials, e.g. corn, milo, barley, wheat, rice, potatoes and tapioca

Glucoamylase Description

Boli GA***0 is made from selected strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. Boli GA***0 has a high conversion rate of starchy substrates into fermentable sugars. Boli GA***0 can hydrolyze alpha-D*1, 4 glucosidic bonds from the non-reducing end of starch one after. This enzyme also hydrolyzes the alpha-D*1, 6 glucoside branch bonds of starch and cleaves the alpha*1, 3 bonds, releasing glucose.

Glucoamylase Characteristics

Glucoamylase Effect Of PH

For maximum activity, the optimal pH for Boli GA***0 is in the range of 3.5 ~ 4.5.

Glucoamylase Applications And Benefits

Boli GA***0 is used to saccharify liquified mash from various sources including corn, milo, barley, wheat, rice, potatoes and tapioca. The resultant glucose product is fermented by yeast to yield ethanol.

Glucoamylase Usage Guiedlines

For ground-grain processing plants using simultaneous saccharification fermentation (SSF), Boli GA***0 may be added directly to the fermenter. For ground-grain dry mill plants and for wet mill plants using a separate pre-saccharification step prior to fermentation, Boli GA***0 may be added to the cooling mash or liquefied starch when the temperature reaches *5 ~ *8°C. Temperatures above *5°C can result in loss of activity.

Glucoamylase Dosage

Boli GA***0 is generally added at a level of 0.7 ~ 0.8 kg/TDS. The actual dosage rate depends on the raw materials, reaction temperature, time and pH of the saccharification/fermentation process, and the desired results in individual plants.
