The Patent is entitled “Construction of highly efficient cellulase compositions for enzymatic hydrolysis of cellulose”.

Dyadic International, Inc. announced today that it has been issued U.S. Patent No. 8,673,618 entitled, "Construction of highly efficient cellulase compositions for enzymatic hydrolysis of cellulose" by the United States Patent and Trademark Office ("USPTO").  

This new patent provides broader intellectual property rights relating to compositions and methods of developing and producing novel enzymes which efficiently convert different sources of plant biomass (e.g. corn stover, wheat straw and bagasse) to fermentable sugars. These sugars can be used in the production of advanced biofuels and bio-based chemicals. 

Methods include processes for degrading plant material using enzyme mixtures and specified enzyme combinations. Enzyme compositions are used to break down specific components of plant biomass (e.g. cellulose, hemi-cellulose, and lignin) into a variety of fermentable sugars.

In addition to claims covering the production of these patented enzymes using Dyadic's C1 Expression System, a wide variety of additional production methods are covered including bacteria, yeast, algae, other fungi and plants.

Dyadic's President and CEO, Mark Emalfarb, stated, "Plant biomass provide a plentiful source of potential energy in the form of sugars that can be utilized to produce advanced biofuels and bio-based chemicals. This latest patent further broadens our family of patents that address the advanced biofuels and bio-based chemicals market. This latest patent also expands our comprehensive intellectual property portfolio further protecting our C1 Expression System, and the products derived therefrom.  We anticipate that broadening our rights for these applications will allow us to further attract additional blue chip customers, partners, and collaborators."
