Global Bioenergies established a breakthrough in its isobutene process to produce the petrochemical compound, using xylose as feedstock.
The process was initially developed using glucose derived from cereals such as wheat or corn.
Global Bioenergies chief operations officer Frédéric Pâques said: “We continue to diversify the resources compatible with the isobutene process.
“Our process shows limited sensitivity to second generation impurities. In addition, it appears robust and highly adaptable to various resources.”

The company said that the performances are similar when carrying out the process with xylose and wheat-derived glucose, or sugar beet-derived sucrose.
Using an advanced synthetic biology approach, Global Bioenergies redesigned the central metabolism of the production strain.
Global Bioenergies CEO Marc Delcourt said: “The valorisation of agricultural and forestry waste is a nascent industry, which represents an important opportunity for Global Bioenergies.
“Once they are available in large quantities, these affordable resources would enable further reduction of bio-isobutene production costs and facilitate technology deployment in the context of volatile petrochemical prices.”
Last month, the company produced bio-isobutene using sucrose as feedstock.
Global Bioenergies is said to be the first company in Europe to develop a process of converting renewable resources into hydrocarbons through fermentation.
It initially focused on the production of isobutene, a key petrochemical building block that is used to produce fuels, plastics, organic glass, and elastomers.
The company operates an industrial pilot plant using its process, and is currently working on a demo plant in Germany.
