摘要：当前,生物制造技术和产业是世界关注的热点。然而,生物过程优化与放大过程中普遍面临以下几个难题,包括:过程检测手段缺乏,难以满足关键指标参数的监控;细胞代谢认知匮乏,无法理性实现过程最优化调控;反应器环境差异大,导致逐级放大效率低下。文中针对以上亟待解决的关键问题,通过案例分析介绍发酵过程实时检测-动态调控-理性放大全链条关键技术创新。在未来,生物过程设计将以集成细胞生理学(时空多尺度细胞代谢模型)和流体动力学(CFD模型)的全生命周期模型为指导,推进计算机辅助设计与开发,加速生物过程实现大规模智能化生产,开启绿色生物制造新时代。
Currently,biomanufacturing technology and industry are receiving worldwide attention.However,there are still great challenges on bioprocess optimization and scale-up,including:lacing the process detection methods,which makes it difficult to meet the requirement of monitoring of key indicators and parameters;poor understanding of cell metabolism,which arouses problems to rationally achieve process optimization and regulation;the reactor environment is very different across the scales,resulting in low efficiency of stepwise scale-up.Considering the above key issues that need to be resolved,here we summarize the key technological innovations of the whole chain of fermentation process,i.e.,real-time detection-dynamic regulation-rational scale-up,through case analysis.In the future,bioprocess design will be guided by a full lifecycle in-silico model integrating cellular physiology(spatiotemporal multiscale metabolic models)and fluid dynamics(CFD models).This will promote computer-aided design and development,accelerate the realization of large-scale intelligent production and serve to open a new era of green biomanufacturing.
