New U.S. Patent Issued To Dyadic International U.S. Patent No. 8,680,252 "Expression and High-Throughput Screening of Complex Expressed DNA in Filamentous Fungi"

JUPITER, Fla., March 27, 2014 /PRNewswire/ -- Dyadic International, Inc. ("Dyadic") (OTCQX: DYAI), a global biotechnology company focused on the discovery, development, manufacture and sale of enzymes and other proteins for the bioenergy, bio-based chemical, biopharmaceutical and industrial enzyme industries, announced today that it has been issued U.S. Patent No. 8,680,252 entitled, "Expression and High-Throughput Screening of Complex Expressed DNA in Filamentous Fungi" by the United States Patent and Trademark Office ("USPTO").

This new patent provides methods for high-throughput screening of DNA libraries for commercially interesting genes.  The ability to rapidly search for and identify novel genes allows for more effective and efficient development of new products.  While this patent broadly covers various filamentous fungi, we believe that the physical characteristics of our C1 organism are exceptionally well-suited towards rapid screening, and protection of this process is therefore of particular significance to Dyadic. 

Dr. Wim van der Wilden, General Manager of Dyadic Netherlands and Head of Dyadic R&D, stated, "High-throughput screening is an important process in developing new enzyme and other protein products.  Sorting through large gene libraries can be a time consuming and tedious process.  Traditional screening methods use one system to identify the genes and another to express or manufacture products from these genes.  Methods described in this patent, which utilizes one system throughout the entire discovery, development, scale-up and manufacturing process, allows us to identify and bring to market better genes, more quickly and with a greater probability of success.  Further, while these processes were originally designed for use with our proprietary C1 Expression System, we believe that they have the potential to be widely applied within our industry and this may be yet another opportunity to out-license our technology."     

This patent is the fifteenth U.S. patent issued to Dyadic adding to its portfolio of 41 international patents, 23 pending international and nine pending U.S. patent applications which cover various features of Dyadic's proprietary technologies. 

The newly issued patent is accessible on the USPTO's website at www.uspto.gov or on Dyadic's website at www.dyadic.com.
