JUPITER, Fla., April 7, 2011 /PRNewswire/ -- 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 bioenergy, industrial enzyme and biopharmaceutical industries, announced today that it has been issued U.S. Patent No. 7,906,309 entitled, "Expression-Regulating Sequences and Expression Products in the Field of Filamentous Fungi" and U.S. Patent No. 7,892,812 entitled, "Chrysosporium Cellulase and Methods of Use" by the United States Patent and Trademark Office ("USPTO").
U.S. Patent No. 7,906,309
"Expression-Regulating Sequences and Expression Products in the Field of Filamentous Fungi"
The inventions embodied by this patent are genes and their corresponding enzymes from glycosyl hydrolase family 10 having xylanase activity which are derived from Chysosporium fungal strains. Other related applications claim cellobiohydrolases and glyceraldehyde phosphate dehydrogenases. These enzymes have proven to be effective in breaking down the major component of plant cell walls, commonly known as lignocellulosic biomass, into fermentable C5 sugars which can be used in the production of biofuels and biochemicals. These genes and enzymes were isolated from Dyadic's patented and proprietary C1 fungus and identified through the genome annotation project conducted by Dyadic in conjunction with Scripps Florida.
Dyadic's President and Chief Executive Officer, Mark Emalfarb, stated, "This patent protects Dyadic's ability to use its C1 technology to make fermentable C5 sugars in addition to the C6 sugars allowed by our previously awarded biofuels patent."
