面向 biomanufacturing/bioprocessing，强调理解互作机制后再构建人工/合成共培养。
核心解读
要点 1
共培养能把复杂路径拆成模块，降低单菌代谢负担和毒性压力。
要点 2
关键难点是中间体传递、成员比例漂移、污染控制和放大稳定性。
要点 3
适合用于复杂底物利用、多步路径和需要互补生理能力的生产过程。
和专题导读的连接
- 概念层：帮助区分“多个菌一起培养”和“成员/功能/互作可定义的合成菌群”。
- 方法层：为成员选择、代谢分工、交叉喂养、群体控制或 DBTL 迭代提供一个切入点。
- 应用层：可作为后续判断生物制造、农业、环境修复或宿主系统文章是否值得深入解读的参考框架。
摘要级内容摘记
The application of microbial co-cultures is now recognized in the fields of biotechnology, ecology, and medicine. Understanding the biological interactions that govern the association of microorganisms would shape the way in which artificial/synthetic co-cultures or consortia are developed. The ability to accurately predict and control cell-to-cell interactions fully would be a significant enabler in synthetic biology. Co-culturing method development holds the key to strategically engineer environments in which the co-cultured microorganism can be monitored. Various approaches have been employed which aim to emulate the natural environment and gain access to the untapped natural resources emerging from cross-talk between partners. Amongst these methods are the use of a communal liquid medium for growth, use of a solid-liquid interface, membrane separation, spatial separation, and use of microfluidics systems. Maximizing the information content of interactions monitored is one of the major challenges that needs to be addressed by these designs. This review critically evaluates the significance and drawbacks of the co-culturing approaches used to this day in biotechnological applications, relevant to biomanufacturing. It is recommended that experimental results for a co-cultured species should be validated with different co-culture approaches due to variations in interactions that could exist as a result of the culturing method selected.
