300,000 U / Ml Glucoamylase Enzyme GD From Starch Substrates Into Fermentable Sugars For Ethanol
Liquid form Glucoamylase ETHMEI GD for Sccharification
High conversion rate from starch substrates into fermentable sugars
Increase Ethanol Yields
DESCRIPTION
Glucoamylase ETHMEI GD is produced from strains of Aspergillus niger through submerged fermentation, extraction and refining processes. ETHMEI GD has a high conversion rate from starch substrates 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 cleaves the α-1, 3 bonds to release glucose.
| Declared Enzyme: | Glucoamylase |
| Systematic Name: | EC 3.2.1.3, 1,4-alpha-D-glucan glucohydrolase |
| Appearance: | Light to dark brown liquid |
| Activity: | 300,000 U/ml (minimum) |
| Product pH: | 3.0 to 5.0 |
| Specific gravity: | 1.10 to 1.20 g/ml |
With its robust glucoamylase activity, ETHMEI GD has found its wide application in the saccharification for the production of ethanol.
ETHMEI GD is designed to ensure the following benefits for ethanol production:
- Improved performance in pre-saccharification process
- Efficient starch/dextrin degradation
- Increased fermentation rate
- Less residual starch in distiller’s grains
- Increased ethanol yields
EFFECT OF PH
ETHMEI GD can work at pH from 3.0 to 5.5. For maximum activity, its optimal pH range is 3.5 to 4.5. See Figure 1.
EFFECT OF TEMPERATURE
ETHMEI GD can work at temperatures from 30 to 65°C with its optimal temperature ranges from 55 to 60°C. See Figure 2.
DOSAGE GUIDELINES
ETHMEI GD is generally added at a level of 0.35 to 0.45kg/TDS. The actual dosage rate depends on the raw materials, processing temperature, pH, reaction time, saccharification and fermentation process at individual ethanol plants.
PACKAGING
ETHMEI GD is packaged in 25kg, 30kg HDPE plastic drums or 1125kg IBC totes. Customized packaging is available upon request.
