Glucoamylase ETHMEI PW is produce from strains of Aspergillus niger through submerged fermentation, extraction and refining processes. ETHMEI PW has a high conversion rate from starches into fermentable sugars. It can hydrolyze α-D-1, 4 glucosidic bonds from the non-reducing end of starch one after another. It can also hydrolyze the α-D-1, 6 glucoside branch bonds of starch and cleave the α-1, 3 bonds to release glucose.
ETHMEI PW is a robust glucoamylase specially designed for ethanol production.
Effect of pH
ETHMEI PW can work at pH from 3.0 to 5.5 with its optimal pH from 3.5 to 4.5. See Figure 1.
Effect of Temperature
ETHMEI PW can work at temperatures from 30 to 65℃ with its optimal temperature range from 55 to 60°C. See Figure 2.
Application and Benefits
ETHMEI PW 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.
ETHMEI PW is designed to ensure the following benefits:
n Increased fermentation rate
n Increased ethanol yields
n Efficient starch/dextrin degradation
n Less residual starch in distiller’s grains
n Improved performance in pre-saccharification processes
For ground-grain processing plants using simultaneous saccharification fermentation (SSF), ETHMEI PW 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, ETHMEI PW 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.
ETHMEI PW is generally added at a level of 0.70 to 0.85kg/TDS. The actual enzyme requirement is dependent on the raw materials, temperature, reaction time, and pH of the individual plant saccharification/fermentation process, and its desired result.
