Codexis Announces First Cellulase Enzyme Scale Up

REDWOOD CITY, Calif., July 12, 2011 /PRNewswire/ -- Codexis, Inc. (Nasdaq: CDXS) today announced the first scale up manufacturing of the company's proprietary cellulase enzymes at commercial scale.  These enzymes are used to convert non-food biomass to fermentable sugars, and ultimately to sustainable products including biofuels and bio-based performance ingredients in household goods such as laundry detergents and shampoos.  

Scale up manufacturing of a prototype cellulase enzyme product is underway at Fermic S.A. de C.V, a contract fermentation and synthesis company headquartered in Mexico City, Mexico.  Enzyme production has been successfully completed at 20,000 liter scale and represents the first manufacture of an enzyme product using the Codexis CodeXporter™ enzyme expression system.  The cellulase enzymes are based on the Codexis CodeEvolver™ directed evolution technology and will be used to support biofuels collaborations and the company's market expansion into sustainable bio-based chemicals.  

"High-performance cellulase enzymes will soon be in high demand for cost-effective production of renewable products from biomass," said Alan Shaw, Ph.D., President and Chief Executive Officer.  "This is both an important commercial milestone for Codexis and a significant development for customers, who are responding to market demand for sustainable products."
