原料粘度高已成为限制薯类乙醇行业发展的问题,中国科学院成都生物研究所采用糖苷键单克隆抗体芯片技术阐明薯类原料粘度成因机制,并开发出具有自主知识产权的降粘酶系和相应的降粘预处理工艺;利用模拟的工业发酵压力条件,选育获得高产物反馈抑制耐性菌株;同时与发酵过程调控工艺、新型高传质反应器系统集成,建立薯类乙醇高效发酵技术体系并成功应用于生产,实现薯类乙醇发酵三大技术突破。
The high viscosity of raw materials has become a problem that limits the development of potato industry. Chengdu Institute of Biology, Chinese Academy of Sciences uses glycosidic bond monoclonal antibody chip technology to elucidate the mechanism of viscosity of potato raw materials and develop the enzyme system with independent intellectual property rights Of the viscosity reduction pretreatment process; the use of simulated conditions of industrial fermentation pressure, breeding high product feedback inhibition tolerance strains; at the same time with the fermentation process control process, a new type of high-mass transfer reactor system integration, the establishment of potato ethanol fermentation technology and efficient system Successfully applied in production, to achieve three major technological breakthroughs in potato ethanol fermentation.
