ZYLOZYME® AA Alpha-Amylase for Bioethanol Production

Optimized for Liquefaction During Ethanol Production

ZyloZyme® AA is a high-performance, non-GMO alpha-amylase designed to enhance liquefaction in ethanol production. Derived from Bacillus subtilis, it reduces mash viscosity and maximizes starch-to-sugar conversion, even at low dosages. ZyloZyme AA delivers reliable enzyme activity at elevated temperatures, helping processors achieve consistent ethanol yields with greater efficiency.

Benefits and Features

  • Effective at very low enzyme‑to‑corn ratios (0.006%)
  • Produces high dextrose equivalents for efficient fermentation
  • Lowers mash viscosity for smoother processing
  • Integrates easily into existing ethanol systems
  • Improves starch liquefaction and mash flow
  • Reduces required enzyme dosage for lower production costs
  • Increases ethanol yield by improving sugar availability
  • Non‑GMO, clean‑label solution for sustainable production

Mode of Action

ZyloZyme AA functions by hydrolyzing internal alpha-1,4-glycosidic bonds in starch, breaking it down into smaller dextrins and sugars. This enzymatic activity rapidly reduces mash viscosity and facilitates conversion of starch into fermentable sugars, boosting dextrose equivalents and ethanol yield. The enzyme’s thermostability allows it to remain active throughout high-temperature liquefaction, ensuring process efficiency and consistency.

Application and Performance

ZyloZyme AA is intended for use during the liquefaction stage of ethanol manufacturing. The product is effective across a range of processing parameters and performs optimally in high-temperature environments up to 203°F (95°C).

In fermentation trials, ZyloZyme AA demonstrated:

  • Significant viscosity reduction. 
  • Enhanced starch conversion. 
  • Performance at just 40% of conventional enzyme dose.

Actual dosage will depend on specific plant conditions and target outcomes.
