Economic and geopolitical factors (high oil prices, environmental concerns, and supply instability) have been prompting policy-makers to put added emphasis on renewable energy sources. For the scientific community, recent advances, embodied in new insights into basic biology and technology that can be applied to metabolic engineering, are generating considerable excitement. There is justified optimism that the full potential of biofuel production from cellulosic biomass will be obtainable in the next 10 to 15 years.
经济和地缘政治因素（高油价、环境问题以及供应不稳定）促使政策制定者更加重视可再生能源。对于科学界而言，近期在基础生物学和可应用于代谢工程的技术方面取得的新进展带来了极大的振奋。有理由乐观地认为，在未来10到15年内将能够充分发挥纤维素生物质生产生物燃料的潜力。
