#GEVO Gevo’s proprietary integrated fermentation technology platform (GIFT®), which has been designed to produce low-cost renewable isobutanol, consists of two elements:
A proprietary yeast biocatalyst, which converts sugars derived from multiple renewable feedstocks into isobutanol, and A proprietary separation unit which is designed to bolt onto existing ethanol facilities.
This production technology is similar to ethanol production, except that Gevo replaces the ethanol-producing biocatalyst with its isobutanol-producing biocatalyst and then adds a separation unit.
Pat Gruber demonstrates how easily isobutanol separates from water.
