Owing to technical improvements in the processes used to produce ethanol from biomass, construction of at least two waste-to-ethanol production plants in the United States is expected to start this year. Although there are a number of robust fermentation microorganisms available, initial pretreatment of the biomass and costly cellulase enzymes remain critical targets for process and cost improvements. A highly efficient, very low-acid pretreatment process is approaching pilot testing, while research on cellulases for ethanol production is expanding at both enzyme and organism level.
由于生物质制乙醇工艺的技术改进，美国预计今年将开始建设至少两座垃圾制乙醇生产厂。尽管有许多强大的发酵微生物可用，但生物质的初始预处理和昂贵的纤维素酶仍然是工艺和成本改进的关键目标。一种高效、低酸的预处理工艺即将进入中试阶段，而用于乙醇生产的纤维素酶在酶和生物体层面的研究都在不断扩展。
