FIBREZYME® G5000 reduces production costs while also improving fiber-to-fiber bonding and pulp refining properties

JUPITER, Fla., March 14, 2012 – Dyadic International, Inc. (“Dyadic”) (OTC Pink: DYAI), a global biotechnology company focused on the discovery, development, manufacture and sale of enzyme and protein products for the industrial enzyme, bioenergy, and biopharmaceutical industries, announced today that it will launch FibreZyme® G5000, a next generation, high performance powder enzyme designed to improve paper quality and improve the economics of various pulp and paper manufacturing processes, in Booth #1065 at the Tissue World Americas conference and exhibition being held at the Miami BeachConvention Center in Miami, Florida from March 20th to March 23rd, 2012.

Thomas O’Shaughnessy, Vice President Sales & Marketing stated, “FibreZyme® G5000 is a great addition to our current FibreZyme®series of products and provides further evidence of the value-adding capabilities of Dyadic’s C1 platform technology. FibreZyme® G5000 operates under wide pH and temperature ranges allowing for seamless integration into most pulp and paper manufacturing processes.”

Specific attributes of FibreZyme® G5000 include the following:

  1. Reduces fiber raw material costs and petroleum-derived chemical usages

  1. Reduces pulp refining energy requirements

  1. Increases paper machine production rates and efficiencies

  1. Improves softness in tissue production

  1. Enhances pulp drainage rates and reduces paper drying demand

  1. Enhances and restores fiber strength and increases inter-fiber bonding through fibrillation

FibreZyme® G5000 is produced using a variant of Dyadic’s patented and proprietary C1 platformtechnology which Dyadic designated as the “white strain” process. Developed through sustained efforts at Dyadic’s research and development facility in the Netherlands, the white strain produces significantly less background proteins, providing a clean background host for targeted production. These changes allow for more efficient and economical industrial scale production of highly targeted enzymes and proteins at greater purity levels.

Tissue World Americas is the only conference and exhibition targeted at North and South American producers, converters, distributors, traders and suppliers of soft hygiene tissue paper. The event will include a technical conference covering new developments in the tissue business and provide a unique opportunity to learn about new techniques and methods to improve operations and profits.
