In Georgia, Lallemand Biofuels has been awarded a patent for its TransFerm Yield+ technology. This invention provides for novel metabolic pathways that reduce or eliminate glycerol production and thereby increase ethanol yield by yeast or other microorganisms.
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.
