130000 U / Ml Glucoamylase Enzyme With Fermentation Efficacy For Distillate Spirits
NON-GMO Glucoamylase For Ethanol
PUREMEI PG
PRELIMINARY DESCRIPTION
Glucoamylase PUREMEI PG is made from NON-GMO strains ofAspergillus nigerthrough submerged fermentation, extraction and refining processes. PUREMEI PG has a high conversion rate of starchy substrates into fermentable sugars. It canhydrolyzeα-D-1, 4 glucosidic bonds from the non-reducing end of starch one after another. It can also hydrolyze theα-D-1, 6 glucoside branch bonds of starch and cleaves the α-1, 3 bonds to release glucose.
PUREMEI PG is designed with a robust glucoamylase activity for saccharification in fuel ethanol production. Use of PUREMEI PG provides higher ethanol yields, faster fermentation and less starch residues.
PRODUCT HIGHLIGHT
A robust glucoamyalse derived from Non-GMO strains of Aspergillus niger, enables faster fermentation, more ethanol yield and less starch residues.

APPLICATIONS AND BENEFITS
- PUREMEI PG 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 or another appropriate microorganism to yield ethanol.
- For ground-grain processing plants using simultaneous saccharification fermentation (SSF), PUREMEI PG 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, PUREMEI PG may be added to the cooling mash or liquefied starch when the temperature reaches 55 to 60°C. Temperatures above 65°C can result in loss of activity rapidly.
DOSAGE GUIDELINES
- PUREMEI PG is generally added at a level of 0.065 to 0.085% w/w (dry solids basis).
- The optimal dose depends on the actual processing conditions including raw materials, temperature, reaction time, pH and the desired results in individual ethanol plants.
