Renewable Isobutene Global Bioenergies' Bio-Isobuten Process Uses now Sucrose
Global Bioenergies has diversified its accessible feedstock for its Bio-Isobutene process. The company has engineered its isobutene production strain through a synthetic biology approach to utilize sucrose as feedstock.
Evry/France – The Bio-Isobutene process, first developed with glucose as a resource, is now adapted for the use of sucrose, the main component of sugar cane and sugar beet. The adaptation of the process to sucrose was one the first technical milestones set as part of IBN-One, the Joint-Venture between Global Bioenergies and Cristal Union. The objective is to build and operate the first full-scale Bio-Isobutene commercial plant to convert sugar beets into 50,000 tonnes bio-isobutene by 2018.
Marc Delcourt, CEO of Global Bioenergies, explained: “Detaining a robust sucrose-utilizing strain is a crucial step forward in the company’s efforts to diversify its accessible feedstock. This is key to ensure global deployment of the technology. Whereas glucose is the major North-American feedstock, sucrose is abundant in Europe and South-America.”
Global Bioenergies has developed a process to produce renewable isobutene from glucose. Glucose is an industrial resource derived from cereals (corn, wheat) or tubers (potatoes, cassava). Sugar beet and sugar cane contain another sugar molecule called sucrose, also known as saccharose.
Whereas yeasts naturally utilize sucrose, bacteria such as Escherichia coli mainly consume glucose. Global Bioenergies’ isobutene process is based on Escherichia coli a platform microorganism for synthetic biology, also known for its industrial robustness. The Company’s main focus was to implement an isobutene production pathway into the microbe. It now also develops new biological modules aiming at diversifying the resources compatible with the process.
