Solazyme Successfully Scales Renewable Oil Fermentation to 500,000 Liters at ADM Clinton, Iowa Facility

South San Francisco, CA (December 13, 2012) – Solazyme, Inc. (NASDAQ: SZYM), a renewable oil and bioproducts company, announced today the successful completion of multiple initial fermentations at ADM’s Clinton, Iowa facility.

The scale achieved at ADM’s Clinton facility is comparable to the fermentation equipment currently under construction at the Solazyme Bunge Renewable Oils facility in Brazil. This 100,000 metric ton annual nameplate capacity facility in Brazil is on schedule to begin operations in Q4 2013.

“Working with ADM’s world class fermentation team to achieve commercial scale operations at the ADM facility shortly after announcing the partnership exhibits our ability to rapidly and successfully scale in large commercial fermentation facilities,” stated Peter Licari, CTO, Solazyme. “Solazyme is currently developing commercial facilities in the US, France and Brazil, and with these runs we have now achieved linear scale-­‐up of over 70,000-­‐fold from our labs.”

Solazyme is utilizing ADM’s existing Clinton, Iowa, manufacturing facility in a capital-­‐efficient expansion of its renewable oil production platform in North America. As part of that arrangement, Solazyme has the ability to fund certain payments with equity rather than cash. To facilitate the equity payments, the Company filed a registration statement with the SEC today.
