Ethanol Production

Liquifying Enzymes

Spezyme® Alpha

  • High activity, thermostable alpha amylase for rapid viscosity reduction and efficient starch conversion.


  • High activity, thermostable alpha amylases for rapid viscosity reduction and efficient starch conversion.

Saccarifying Enzymes

Distillase® ASP

  • High activity glucoamylase with debranching enzymes for complete hydrolysis to glucose.

GA-L New

  • High activity glucoamylase.

Cellulose Based Biomass Processing


  • Range of high activity cellulase enzyme complex for the conversion of cellulose that has undergone a pre-treatment process such as ammonia explosion, acid digestion or steam expansion.  This cellulase formulation will facilitate process development and scale-up for the renewable fuel industry.
