Lallemand Biofuels & Distilled Spirits and Mascoma LLC are proud to announce that Lallemand has been awarded a patent (US 8,956,851 B2) for the technology that is used in TransFerm Yield+. This invention provides for novel metabolic pathways that reduce or eliminate glycerol production and thereby increase ethanol yield by yeast or other microorganisms. This method was originally filed in April 2012 and the patent was granted on Feb. 17, 2015.

During the past three years, LBDS and Mascoma introduced TransFerm and TransFerm Yield+ yeasts into the ethanol industry in order to help producers reduce the amount of glucoamylase needed in fermentation and also to provide a substantial yield increase through the introduction of this glycerol reduction pathway. Since that introduction over 50 plants have utilized the TransFerm platform producing over 4 Billion gallons of ethanol.

“We are extremely proud to have introduced these products into the marketplace. This drop-in, game-changing technology is one example of how our Mascoma business unit has produced real results,” said Angus Ballard, president of LBDS. “To be able to increase yields and thus increase the profitability of ethanol plants, at a time where margins are tight, is huge. This is just the beginning of a long line of Mascoma developed products that will be brought into the market by our team.”

“Development of this technology is the result of years of dedicated R&D effort by Mascoma,” said Kevin Wenger, executive vice president of Mascoma. “We are quite pleased that the U.S. Patent Office has allowed the patent; we believe it shows how innovative and significant this new approach really is. TransFerm Yield+ is truly the first product of its kind to offer this type of step change technology in ethanol production.”
