    SOUTH SAN FRANCISCO, Calif., April 15 /PRNewswire/ -- A recent test of
 Solazyme biodiesel, Soladiesel, through the Southwest Research Institute
 (SWRI), by request of the U.S. Department of Defense (DoD), demonstrated
 that Soladiesel has superior cold weather properties to any commercially
 available biodiesel. This makes it more suitable for cold weather climates
 where military bases have been previously unable to use biodiesel.
 Solazyme, Inc. is a leading biotechnology company that harnesses the power
 of microalgae to produce clean and scalable high performance oils,
 biofuels, and "green" chemicals. Company CEO Jonathan Wolfson will present
 at the 2008 Worldwide Energy Conference & Trade Show, and will discuss how
 oils derived from algae can be processed to create high-grade FAME
 biodiesel, renewable diesel and jet fuels that meet current military
 specifications. Because of the excellent cold temperature performance and
 the clean characteristics of the oil, former military fuels specialists
 note that new algae-based fuels could soon help the DoD to better comply
 with recently enacted mandates to reduce our dependence on foreign oil and
 utilize environmentally friendly fuels, including biodiesel.
     "The DoD's requested testing of the Soladiesel fuel showed superior
 performance especially in terms of its cold temperature properties," said
 Wolfson. "Greater performance in cold temperatures means our biodiesel and
 other algae-based fuels could help the military in remote northern
 locations like Alaska and North Dakota, as well as in hot climates, while
 reducing dependence on petroleum. We look forward to continuing to work
 with the DoD on Soladiesel and other algal based fuels, and are pleased to
 be presenting at the DESC conference."
     Soladiesel exceeds both the requirements of the American Society for
 Testing and Materials (ASTM) biodiesel standard D6751 and EN 14214, the
 European standard, which ensures that biodiesel can safely run in any
 existing diesel engine. A 2008 Ford F450, which was supplied by BioDiesel
 University, part of the Smith School of Business at the University of
 Maryland, was used to demonstrate Solazyme's biofuel at the DESC
 conference, running on its original, factory-standard diesel engine with no
 modifications. The truck is powered by B100; that is, 100 percent biodiesel
 made from 100 percent algae.
     R. James Woolsey, former Director of Central Intelligence and Under
 -Secretary of the Navy, who arrived at the Conference in the unmodified
 Ford F450 powered by Soladiesel said, "While I drive a plug-in hybrid, the
 military generally doesn't use cars; it drives trucks, ships and planes and
 today those only run on diesel oil-based fuels. I'm delighted to
 participate in this worldwide first -- I arrived at the DESC Military
 Energy Conference in a F450 pick-up fueled completely on ASTM compliant
 B100 made from domestically produced algal oil. Algae are a natural oil
 producer and can be refined into all kinds of oil-based fuels. This shows
 we're on our way to growing our own military fuels right in this country."
     "Solazyme's crude algal oils can be blended with petroleum crude in
 existing oil refineries and are also optimal for refining into biodiesel,
 renewable diesel and jet fuel," Wolfson said. "Therefore we anticipate
 helping to diversify and decentralize the geographic sources of oil, thus
 making oil supplies more secure. In addition, Solazyme's oil has a clear,
 fast path to market because the algal oil was developed for use within the
 existing trillion dollar energy infrastructure."
     The 2008 Worldwide Energy Conference & Trade Show is being held April
 14 - 16 at the Hyatt Regency Crystal City in Arlington, Va. The truck will
 also be available for rides throughout the day by interested parties.
 Wolfson's presentation, titled Fuels Derived from Algae Oil, is scheduled
 for 9:00 am on April 16, 2008.
