The amazing corn kernel just became more amazing!

Introducing Enogen Corn®

®

Corn has Come a Long

Way Over the Course of

the Last 7000 Years

®

That Little Kernel – is full of little Goodies!

Great Energy Source ~7500 btu’s/lb

3 Major Components

• Pericarp ~ 6% of the Kernel – But 50% of Fiber in the Kernel

• Endosperm ~ 80% of Kernel– Starch

– Source of energy for the germinating seed

– 2 Components

• Floury Endosprem: is the softer more accessible starch

• Horneous Endosperm: harder to access starch as granules are embedded in a dense protein matrix

• Germ 12% of the Kernel – Comprised 25% fat (corn oil)

– Essential Amino Acids

®

The Amazing Kernel

Is a great feedstock full of all those goodies, and it is;

• Energy Dense

• Easy to ship

• Stores Well

®

Amazing Kernel Continues to Evolve

• Over the Course of the last 30 years Corn Yields have almost doubled

• Improved Genetics

• Molecular Breeding

• Biotechnology (Traits)

®

Next Step in the Evolution of that Amazing Kernel

Enogen Corn

®

Robust, optimized alpha-amylase enzyme delivered directly in the corn grain required by every ethanol plantC

What is Enogen “corn-expressed amylase”?

Broad Temperature Range and pH Tolerance

alpha-amylase

Features

®

Enogen is a Thermostable Alpha

• Optimal Operating Temp 194 F or 90 C

• Denaturing Begins to Occur at 238 F or 115 C after 8 minutes

• No issues with Jet Cooker

• No Need for Secondary Alpha Dose

Syngenta Public Information

®

• +90% Activity from 4.2 – 6.0 pH

• No pH Adjustment Required in Cook

• Eliminating NH3 addition to Cook

• Reducing Sulfuric Additions for pH Adjustment

• Broad pH Tolerance

Enogen Corn has Broad Range pH Tolerance

®

Enzyme’s Unique Mode of Action

• Enogen’s Mode of Action: exhibits a random attack which quickly reduces chain length.

• This rapid reduction in the amylose chain length leads to a dramatic break in viscosity.

• Conventional alphas exhibit a multiple attack which generates smaller reducing sugars without significantly reducing chain length.

• The difference in enzyme mechanics

cannot be overcome by increased

dosage.

®

• Improved Starch Hydrolysis
