为什么放进合成菌群专题
面向小分子生物制造，梳理线性分工、模块化路径拆分和互养式共培养设计。
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
Microbial consortia were designed for the production of small molecules with 'labor' being divided between two or more microorganisms. Examples of linear designs are substrate conversion preceding target molecule production or subdivision of two consecutive steps of target molecule production. Here, we review synthetic biology design approaches for microbial consortia based on ecological principles and microbial interactions that is, mutualism, and commensalism. Besides highlighting the technical challenges regarding industrial application of synthetic microbial consortia, we forecast the extension of the concept from binary linear to ternary linear and more complex microbial consortia in biotechnological applications. Microbial consortia are here reviewed and proposed as a rational solution toward feedstock accessibility as it has been shown for production of l-lysine, l-pipecolic acid and cadaverine from starch or production of fumarate from microcrystalline cellulose and alkaline pre-treated corn, or alternatively to establish new multi-step pathway for the production of rosmarinic acid from xylose and glucose.
