标题： Living porous ceramics for bacteria-regulated gas sensing and carbon capture

摘要： 寄主于非生物结构中的微生物已促成可生长、感知和适应的工程化活材料，其方式模仿了生物系统。 尽管多孔结构应有利于微生物的定殖，但它们尚未被开发为非生物支架以用于活材料的发展。 在此，我们报告了一种由细菌定殖的多孔陶瓷，形成了具有自我调节和基因编程碳捕获及气体传感功能的工程化活材料。 碳捕获能力通过野生型光合蓝藻实现，而气体传感功能则利用经过基因改造的大肠杆菌生成。 分级多孔粘土用作陶瓷支架，并从细菌生长、吸水性和机械性能方面进行了评估。 使用最先进的化学分析技术，我们证明了这种活的多孔陶瓷能够直接从空气中捕获CO2，并将微量有毒气体代谢转化为人类可察觉的良性气味。 显示英文摘要

摘要： Microorganisms hosted in abiotic structures have led to engineered living materials that can grow, sense and adapt in ways that mimic biological systems. Although porous structures should favor colonization by microorganisms, they have not yet been exploited as abiotic scaffolds for the development of living materials. Here, we report porous ceramics that are colonized by bacteria to form an engineered living material with self-regulated and genetically programmable carbon capture and gas-sensing functionalities. The carbon capture capability is achieved using wild-type photosynthetic cyanobacteria, whereas the gas-sensing function is generated utilizing genetically engineered E. coli. Hierarchical porous clay is used as ceramic scaffold and evaluated in terms of bacterial growth, water uptake and mechanical properties. Using state-of-the-art chemical analysis techniques, we demonstrate the ability of the living porous ceramics to capture CO2 directly from the air and to metabolically turn minute amounts of a toxic gas into a benign scent detectable by humans.
