In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of 10 larger than previous trials conducted at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov)...

Squalane, an emollient used in cosmetics, will be the first product of a biotechnology pilot plant now being started up by Nucelis Inc. (San Diego, Calif.; www.nucelis.com), a spin-off from Cibus (also of San Diego). The plant will use Cibus’ Rapid Trait Development System (RTDS), a new gene-editing technology, to enable naturally occurring yeast to increase their production of squalene, the...

Lately there has been much renewed interest in fermentative production of n-butanol from renewable biomass as an industrial solvent and liquid fuel superior to ethanol that could be used as a substitute for gasoline. An improved butanol production through the reinforcement of the direct butanol-forming route in Clostridium acetobutylicum has been reported by a Korean team, which includes scientists from...

Linde Gases (Murray Hill, N.J.; www.linde-gases.com) has developed a novel cryogenic technology that promotes uniformity in the formation of ice crystals during freeze-drying (lyophilization) processes for proteins, vaccines and other injectable pharmaceutical products. Lyophilization involves freezing a solution of the product, then reducing the surrounding pressure to allow the water to sublimate...

This month, Borregaard Industries Ltd. (Sarpsborg, Norway; www.borregaard.com) will start up an integrated, pilot-demonstration plant to further develop a new pretreatment process for converting biomass into lignin and fermentable sugars. Located at the company’s R&D Center in Sarpsborg, the pilot plant will convert up to two metric tons (m.t.) of feedstock per day. The fully integrated facility...

A new yeast strain that could one day substitute for petroleum as a source of surfactants for detergents, soaps and cosmetics has been identified by researchers at the U.S. Dept. of Agriculture’s National Center for Agricultural Utilization Research (Peoria, Ill.; ars.usda.gov). The yeast, not yet named, is a member of the Candida genus of yeasts and produces sophorolipids (a sugar-based...

In June, the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) announced the winners of the 2011 Presidential Green Chemistry Challenge Awards. Winners of the Challenge, which promotes R&D of less hazardous alternatives to existing technologies that reduce or eliminate waste in industrial production, are selected by an independent panel convened by the Americal Chemical Soc...
