Qteros and UMass Amherst Bolster Patent Portfolio for Ethanol-Producing Microbe With Issued and Allowed Patents in the United States and Japan

MARLBOROUGH, Mass., June 27, 2011 /PRNewswire/ -- Qteros, Inc., the developer of a unique and highly efficient Consolidated Bioprocessing (CBP) platform for the lowest-cost production of cellulosic ethanol, and the University of Massachusetts Amherst, today announced two significant intellectual property (IP) advances that extend the patent estate for their unique ethanol-producing microorganism, Clostridium phytofermentans, also known as the Q Microbe®.

The United States Patent and Trademark Office issued US Patent 7,943,363 B2 covering genetic constructs of Clostridium phytofermentans. This patent is significant as it provides intellectual property protection for genomic development and the use of gene combinations in Clostridium phytofermentans and other microorganisms to enhance an organism's innate ability to hydrolyze biomass and improve the efficiency and yield of ethanol produced by an organism.

In a second but related advance, the Japanese Patent and Trademark Office allowed a patent titled, "Systems and Methods for Producing Biofuels and Related Materials."  The patent describes the novel creation of products through the fermentation of biomass by Clostridium phytofermentans. Patent allowance in Japan represents significant progress towards the broad, global protection of Clostridium phytofermentans bioprocessing outside of the United States. A patent has already been issued for this technology in the U.S.

Both patents are based on the discovery of Clostridium phytofermentans by microbiologists at the University of Massachusetts Amherst. Qteros is the exclusive licensee of the patent.

John A. McCarthy, Jr., Qteros' President and Chief Executive Officer, stated, "Each of these key patent achievements expands and further bolsters Qteros' already strong IP portfolio and represents the latest successes in our proactive and aggressive intellectual property strategy. Combined with the broad protection enabled by Qteros' current patent estate, these patents reinforce the uniqueness and the potential of our biological platform and enable Qteros to achieve an important milestone as we and our partners rapidly progress towards commercialization of our platform to produce lowest cost cellulosic ethanol at commercial scale."

Qteros' CBP Platform: Enabling Lowest Cost Production of Cellulosic Ethanol

The uniqueness of Qteros' CBP platform is centered on the Company's proprietary microorganism, the Q Microbe® (Clostridium phytofermentans) - a naturally occurring "biorefinery" that produces virtually all enzymes required for biomass degradation into pentose and hexose sugars, while simultaneously co-fermenting all these sugars into ethanol as its natural metabolic end product. The organism's innate biological ability to produce ethanol from biomass enables Qteros to focus its development efforts on optimizing the organism's effectiveness for industrial-scale production. This highly streamlined engineering solution therefore results in significantly lower operating and capital costs of production for producers versus other competitive technology solutions. Moreover, the Q Microbe® is feedstock flexible, producing high yields of cellulosic ethanol from a broad range of non-food biomass materials, including, among others, sugarcane bagasse, corn stover and cobs, and a broad variety of energy crops.
