Diversa and Valley Research Launch New Enzyme for More Efficient Ethanol Production

SAN DIEGO and SOUTH BEND, Ind., June 30 /PRNewswire-FirstCall/ – Diversa Corporation and Valley Research, inc. announced today the commercial launch of “Ultra-Thin” enzyme, a new product designed to significantly improve the efficiency and economics of ethanol production. Developed by Diversa and marketed under the “Ultra-Thin” label by Valley Research, this new product operates at high temperature and at a lower pH than other commercially available enzymes, which offers the potential for substantial cost savings.

“Ultra-Thin” enzyme is a novel, next-generation alpha amylase enzyme designed to offer ethanol producers superior liquefaction performance. It works in concert with other enzymes to efficiently convert the starch present in corn into sugars that can then be processed into ethanol or other value-added products such as high fructose corn sweetener. Ethanol producers have traditionally used other alpha amylase enzymes that operate at a sub-optimal pH, requiring costly process changes to adjust the pH of the production process. Because “Ultra-Thin” enzyme is capable of operating robustly at pH 4.5 – the same pH of the production process – it can help producers to lower their operating costs significantly. This enzyme has received FDA approval for use in ethanol and sweetener production as well as additional applications.

Under a multi-product agreement between the two companies, “Ultra-Thin” enzyme will be distributed by Valley Research exclusively in the U.S. and selected countries for fuel ethanol and sweetener applications. Diversa manufactures Ultra-Thin enzyme under its agreement with Fermic S.A. de C.V. Diversa and Valley Research are jointly pursuing additional development programs and marketing and distribution relationships for other Diversa enzyme products as well.

“The starch processing industry has been asking for a pH 4.5 alpha amylase enzyme for almost 30 years, and Diversa has successfully developed the first product to satisfy this unmet need,” stated Art Sears, President of Valley Research. “We look forward to demonstrating the value of Ultra-Thin enzyme to ethanol producers and launching additional enzyme products with Diversa.”

“The launch of Ultra-Thin enzyme is consistent with Diversa’s record of developing differentiated enzyme products that significantly improve process performance and reduce operating costs,” said William H. Baum, Diversa’s Executive Vice President, Bioscience Products. “Valley Research has over 20 years of experience in the food and specialty enzyme business, and we’re excited to leverage their marketing and distribution capabilities to bring innovative new products like Ultra-Thin enzyme to the bioethanol market.”

According to the Renewable Fuels Association, the U.S. ethanol industry produced a record 3.41 billion gallons in 2004, representing a 21% increase from 2003 levels and more than double the amount produced in 2000. In addition to the 81 existing ethanol plants located in 20 states, at the end of

2004, 16 plants and 2 major expansions were under construction, representing an additional 750 million gallons of production capacity.
