Specialty fungal alpha amylase for use in saccharification and fermentation

Safety Sheet | Data Sheet


XT-SR is an endo-amylase that hydrolyzes(1,4)-alpha-D-glucosidic linkages in starch polysaccharides. This alpha amylase converts undigested starch into dextrins that can be hydrolyzed by the GA to produce glucose for improved fermentation.

Typical Characteristics

  • Activity: 100,000 AAF-D
  • Appearance: Light to Dark Brown liquid
  • pH: 4.0–9.0
  • Bulk Density: 1.16 –1.2 g/mL

Dosage Recommendation

XT-SR should be dosed at 0.005–0.015% 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.

Regulatory Status

  • ISO 9001 registered company
  • Kosher certified
  • GRAS (Generally Recognized as Safe)

GM Status

This product 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 effectiveness are improved by means of modern technology.


XT-SR is available in 1,100 KG totes.


XT-SR will meet the declared activity upon arrival at your plant.

Recommended storage: 0–10⁰C (32⁰–50⁰F). Packing must be kept intact, dry, and away from sunlight. Please follow the recommendations and use the product before the best before date to avoid theneed for a higher dosage.

Best before: The best-before date can be found in the COA or on the product label. The product gives optimal performance when stored as recommended and used prior to the best-before date.

Safety and Enzyme Handling

Enzymes are proteins.  Inhalation of dust or aerosols may induce sensitization and may cause allergic reactions in sensitized individuals.  Some enzymes may irritate the skin, eyes, and mucus membranes upon prolonged contact. See the Safety Data Sheet for further information regarding safe handling of the product and spills.
