Lesaffre launches new yeast product
EPA grants fuel pathway approval to Gevo
Lesaffre Yeast Corp. recently inaugurated a drying facility in Headland, Alabama, and celebrated the launch of Leaf – Lesaffre Advanced Fermentations’ new bioengineered yeast for ethanol production. The new yeast, ER-Xpress, is a robust enzyme-expressing yeast specifically developed for the U.S. ethanol industry. The new strain will be produced and dried at the new facility in Headland. “Lesaffre is pleased to invest and extend its industrial yeast manufacturing network in the USA. This new yeast-drying capacity will enable us to continue to develop tailored products and to address our white biotech customers’ development strategies,” Baule said. The Headland facility represents Lesaffre’s first yeast drying facility in the U.S. The company and Red Start Yeast, however, have operated a cream yeast facility in the city since the 1990s.
In early January, the U.S. EPA posted a notice to its website announcing the agency has approved a fuel pathway filed by Gevo Inc. for the production of butanol from corn starch and grain sorghum. The pathway approval applies to both D5 advanced biofuel and D6 renewable fuel renewable identification numbers (RINs). Within the approval, the EPA states that Gevo’s butanol produced from corn starch feedstocks appears to already qualify under an existing pathway for the production of D6 RINs, assuming the company satisfies the pathway specifications and other requirements specified in the Clean Air Act and regulations. The EPA also said it has determined that butanol produced by the Luverne facility from grain sorghum feedstock can qualify for D-code 6 RINs, and butanol produced by
