| 3 | Biobutanol will be the first of those biofuels to reach global markets. | |
| 4 | "Most important about this discovery is TU-103's ability to produce butanol directly from cellulose," said Mullin. | |
| 5 | Also, build an industrially scalable bioreactor and a new way to recover butanol from the reactor. |
