Novonesis Fiberex® F2.5 is an enzymatic solution designed to maximize in-process corn kernel fiber conversion. It is a targeted blend of hemicellulase and cellulase activity that provides best-in-class performance for fiber enzymes added to fermentation. 

  • Access low carbon fuel markets. 
  • Unlock up to 15% more corn oil from the fiber matrix 
  • Reduce residual starch by 18% 
  • Higher xylanase percentage 

This drop-in solution is the optimal blend for in-process conversion of fiber into cellulosic ethanol, and reduces the barrier to low carbon fuel markets to generate cellulosic ethanol without the need for CAPEX-intensive projects.   

Product features, details and benefits

  • Enhance corn oil recovery

    Unlock up to 15% more corn oil from the fiber matrix, enabling it to be used for animal feed or sustainable biodiesel production.


  • Reduce residual starch

    Reduce residual starch by 18% to gain further performance on ethanol generation.


  • Boosts corn oil yieldThis product frees corn oil trapped in the fiber matrix. That means you can expand a major revenue stream by extracting more corn oil.

  • Boosts fiber-based ethanol yieldsThis product generates sugars from the fiber matrix, making them available to the yeast. That means you can convert a low-value animal feed into high-value ethanol. In many markets, this low-carbon ethanol has a reduced carbon score, so it can bring even more value to your plant.

  • Maximizes starch-based ethanol yieldsThis product helps you squeeze every last drop of ethanol from your starch-based feedstocks. It breaks down tough fibers to make residual starch available for conversion. That maximizes your starch-based ethanol yields.

  • Reach Low Carbon Fuel Standard (LCFS) and/or Renewable Fuel Standard (RFS)

    With this product, your fiber-based ethanol can reach certain low-carbon standards, which increases the value of your output.


  • Lowest Carbon Intensity of enzyme blendDelivered enzyme is a component of carbon intensity scoring. Reducing the addition of cellulase to the smallest volume will reduce a plants CI score, possibly by 1-2 points.

  • Access to low carbon fuel markets

    Unlock the full value of every corn kernel by enhancing fiber ethanol generation with industry-leading yields


  • Suitable for drop-in-processes

    This product is designed to enable in-process fiber-to-ethanol conversion.


Fiberex® F2.5 is an enzymatic solution used to maximize in-process corn kernel fiber conversion. This drop-in solution reduces the barrier of entry to low carbon fuel markets by enabling producers to generate cellulosic ethanol without the need for CAPEX intensive projects.

Added to fermentation in existing first-generation ethanol plants, Fiberex® F2.5 breaks down fiber found in the corn kernel to significantly enhance performance benefits. In breaking down the tough fiber matrix, this enzyme blend increases fiber conversion for cellulosic ethanol produced in an SSF process.
 

This product contains enzymes. While enzymes are safe to use in consumer applications, they need correct handling in working environments to ensure workers’ safety.

Indeed, repeated inhalation of enzyme dust or aerosols resulting from improper handling may induce sensitization and may cause allergic type 1 reactions in sensitized individuals.

Please follow the precautionary handling recommendations below:

The referenced media source is missing and needs to be re-embedded.
  • Avoid breathing dust/fume/gas/mist/vapors/spray
  • Avoid contact with eyes, skin, or clothing
  • In case of inadequate ventilation wear respiratory protection
  • IF INHALED: Remove person to fresh air and keep comfortable for breathing
  • If experiencing respiratory symptoms: Call a POISON CENTER or a doctor
  • Store in a dry place. Store in a closed container
  • Dispose of contents/containers in accordance with local regulations
