Get to know us

Fiberex® is a blend of enzymes designed to target and break down the complex matrix of every corn kernel. It converts fiber to simple sugars so you can produce fiber-based ethanol more easily and unlock the full value of your feedstock.

What can this mean for your plant? Find out below.

Enzymes for fiber conversion

Fiber conversion

Ethanol

Although fiber makes up 10% of a corn kernel, very little of this fraction is used during starch-based ethanol production due to difficulty converting the matrix of cellulose, hemicellulose, starch, protein, oil, and minerals.

Watch our video to learn more about this process.

Unlock the potential of your corn fiber - with Fiberex®

Unlock the value of your corn fiber

Find out how Fiberex® can help you reimagine ethanol.

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

Boosts corn oil yield

This 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.

Boosts fiber-based ethanol yields

This 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.

Maximizes starch-based ethanol yields

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

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

Delivered 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.

Lowest Carbon Intensity of enzyme blend

This product utilizes a second enzyme for maximal performance.

Product application

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

Suitable for drop-in-processes

Benefits

Fiberex® F1 breaks down tough fibers in the corn to deliver significantly more corn oil. It also delivers additional high-value, low-carbon ethanol. Its a drop-in technology, which means minimal CAPEX investment for your plant.

Details

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:

Fiberex® F2x is an enzymatic solution used for in process kernel fiber converstion.  This drop in solution reduced the barrier to low carbon fuel markets by enabling producers to generate cellulosic ethanol without the need for CAPEX intensive projects or potential risk to back end viscosity.

Added to fermentation in existing first generation ethanol plants, Fiberex® F2x breaks down fiber found in corn kernel to significantly enhance performance benefits.  In breaking down the tough fiber matrix, this enzyme blend increases fiber conversion for celluloisc ethanol produced in an SSF process.

Fiberex® F2x is your first choice as an enzymatic solution used for 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® F2x increases fiber conversion for cellulosic ethanol produced in-process, by utilizing enzyme activities that target the roughly 60% of fiber that is hemicellulose. This blend is uniquely able to break down important layers of the fiber that enhance cellulase conversion and result in more fiber conversion while releasing more corn oil and residual starch.

Fiberex® R1 for bolt-on solutions delivers significantly more high-value, low-carbon ethanol and more corn oil. That’s because bolt-on solutions allow for a pre-treatment step that combines with the enzymes to break down even more tough fibers in the corn. 

The fiber matrix is mostly made up of cellulose and hemicellulose strands, coated with protein.  This protein-fiber network traps residual starch. It also binds water and oil. The enzymes in the Fiberex® R1 blend target and break down multiple fractions within the tough fibers. That frees residual starch and trapped oil to boost your fiber ethanol and corn oil yields.
