目的:对美国的生物乙醇技术的进展进行深入挖掘。方法:以专利计量的分析方法,借助可视化的分析工具,对美国生物乙醇技术的专利文献从技术生命周期、IPC小类重点分布、专利权人专利申请及其技术应用重点进行分析。结果:研究发现近年来美国生物乙醇技术的发展进入了迅速的成长期;技术应用重点集中在微生物发酵、酶解、转基因植物新品种等领域;杜邦公司和先正达公司技术重点集中在转基因新品种的研制,诺维信公司和丹尼斯克公司技术重点集中在生物酶的研制。结论:美国生物乙醇技术发展迅速,这与美国政府的支持有关,也证明美国的基础科学转化率很高。
Objective: To explore the progress of bio-ethanol technology in the United States. Methods: By means of patented analysis method, with the aid of visual analysis tools, the patent documents of American bioethanol technology were analyzed from the aspects of technology life cycle, IPC sub-classifications, patentee patent applications and their technical applications. Results: The study found that in recent years, the development of bio-ethanol technology in the United States has entered a period of rapid growth. The application of technology has focused on the fields of microbial fermentation, enzymolysis and new varieties of transgenic plants. The technologies of DuPont and Syngenta have focused on new genetically modified Variety of research and development, Novozymes and Danisco technology focused on the development of biological enzymes. Conclusion: The rapid development of bio-ethanol technology in the United States, which is related to the support of the U.S. government, also proves that the basic sciences in the United States have a high conversion rate.
