Glucoamylase ETHMEI®

ETHMEI® is a family of five high activity glucoamylases that has been specifically designed and formulated for the fuel ethanol industry. ETHMEI® glucoamylases provide the highest possible conversion rate of starch into fermentable sugars.The ETHMEI® product line offers a cost-in-use savings unmatched by any commercial glucoamylase currently available in the market.


ETHMEI® is a group of glucoamylases produced from a selected strain of Aspergillus niger.  Designed with a very high glucoamylase activity, the use of ETHMEI® in the fuel ethanol industry maximizes starch conversion. ETHMEI® products formulated with trehalase and/or pullulanase achieve the fastest fermentation, lowest residual starch, and the highest ethanol yield.
