CTE Global Glucoamyl L-209+

CTE Global Glucoamyl L-209+ is a purified native gluco-amylase that functions by the hydrolysis of terminal 1,4 linked alpha-D-glucose residues from non-reducing ends of polysaccharide chains with release of beta D-glucose. Its application is to yield monomeric glucose molecules that can be fermented by yeast into biofuels of interest such as ethanol.

Performance Benefits

Glucoamyl L-209+ provides the following benefits to ethanol producers:

  • Robust and consistent performance under varied conditions.
  • Enzyme conversion kinetics match more closely to yeast growth curve.
  • Increased alcohol concentrations.
  • Lower residual sugars at end of fermentation.
  • Reduced glycerol concentrations throughout fermentation.
GM Status

This is not a GMO. The enzyme product is manufactured by fermentation of microorganisms that are not present in the final product. The production organisms and the enzyme’s effectiveness are improved by means of modern biotechnology.

Applications & Uses

Application Recommendations
  • Glucoamyl L-209+ is used to saccharify liquefied mashes of whole ground corn. The resultant glucose is fermented by yeast to produce ethanol.
  • Glucoamyl L-209+ has a broad operating range for enhanced process flexibility, and performs well within the temperature, and pH ranges typical in whole ground corn batch fermentations.
  • In high gravity fermentations, performance can be further enhanced by the addition of SZM XT-20 Fungal Alpha Amylase and/or SZM AP-1 Acid Protease.
Dosage Recommendation

Glucoamyl L-209+ should be dosed at 0.048 - 0.065% weight enzyme / weight as is corn. The actual dose required will depend upon the conditions of your fermentation: time, initial pH and the level of solids.

Technical Details & Test Data

Unit Definition

One unit of glucoamylase (u) is the amount of enzyme which hydrolyzes soluble starch to liberate 1 milligram of glucose per hour under the conditions of the assay.

Safety & Health

Safety and Enzyme Handling

Glucoamyl L-209+ contains proteins obtained from large-scale cultures of a mold. Proteins may cause an allergic-type reaction in sensitized individuals that could require immediate medical attention. Prolonged direct contact may cause minor irritation to skin, eyes, or mucus membranes.
