Glucoamylase FERZYME PW

FERZYME PW is a food grade enzyme designed for saccharification in brewing industry such as potable alcohol production and production of highly attenuated low carbohydrate beers and improved attenuation.

Product Description

Description
Glucoamylase FERZYME PW is made from non-genetic modified strains of Aspergillus niger using submerged fermentation, extraction and refining techniques. FERZYME PW can catalyze the release of glucose units from the non-reducing ends of soluble dextrins by hydrolyzingα-1,4 glucoside linkages and also slowly hydrolyzing α-1,6 glucoside linkages.
FERZYME PW is a food grade enzyme designed for saccharification in brewing industry such as potable alcohol production and production of highly attenuated low carbohydrate beers and improved attenuation.
