For the first time, Mi-Hy brings together Microbial Fuel Cell (MFC) technology and hydroponics, thereby introducing a prosthetic rhizosphere (an extended rhizosphere community) to the typically “soil-less” configuration of hydroponics systems. The Mi-Hy system will modulate nitrogen forms, plant root microbiomes optimise nitrogen uptake, and mobilise phosphorous, averting the need for chemical fertilisers. This circular, sustainable platform turns carbon into biomass and reclaims nitrogen from wastewater streams. Linked through shared microbiomes, the bioelectricity generating Bioelectrochemical System (BES) Microbial Fuel Cell (MFC) platform is: i) optimised to generate electricity from wastewater at 1mW/1mL feedstock (setting a new benchmark for MFCs); ii) driving wavelength-specific LEDs to optimize photosynthesis; iii) capable of recovering useful biomolecules using adjacent MFCs to modulate the redox potential of a workhorse Microbial Electrolysis Cell (MEC) performing microbial electro synthesis (MES). This novel development brings together MFCs & MECs. Since these share common microbial constituents, they can be technologically combined without the need for external, (fossil-fuel based) energy sources. To achieve this goal, Mi-Hy aimsto design biofilms using metabolic engineering in wild type symbiotic strains. This next-generation hydroponics system has near-future applications in agriculture and in the urban environment. It delivers a smart, decentralized, low power digital infrastructure with sustainable organic solutions, which are in line with the ambitions of the Missions Cities & Climate adaptation (urban agriculture, precision gardening, wastewater treatments, energy generation,synthesis of high value compounds e.g., vitamins). Mi-Hy will also invite designers and stakeholders from various sectors to co-create future applications. Ultimately, it anticipates and facilitates a healthier, sustainable, nature-based urban landscape.

Mi-Hy首次将微生物燃料电池（MFC）技术和水培技术结合在一起，从而将人工根际（扩展的根际群落）引入到典型的“无土”水培系统配置中。Mi-Hy系统将调节氮的形式，植物根系微生物组优化氮的吸收，并动员磷，避免对化肥的需求。这个循环的可持续平台将碳转化为生物质，并从废水中回收氮。生物电化学系统（BES）微生物燃料电池（MFC）平台通过共享的微生物组连接起来：i）优化为以1 mW/1 mL原料从废水中发电ii）驱动波长特定的LED以优化光合作用; iii）能够使用相邻的MFC来回收有用的生物分子，以调节主力微生物电解池（MEC）的氧化还原电位，进行微生物电合成（MES）。这一新的发展将MFC和MEC结合在一起。由于它们具有共同的微生物成分，因此可以在技术上将它们结合起来，而不需要外部（基于化石燃料的）能源。为了实现这一目标，Mi-Hy旨在利用野生型共生菌株的代谢工程设计生物膜。这种下一代水培系统在农业和城市环境中有着不久的未来应用。它提供了一个智能，分散，低功耗的数字基础设施与可持续的有机解决方案，这是符合使命城市和气候适应（城市农业，精密园艺，废水处理，能源发电，高价值化合物的合成，例如，维生素）。Mi-Hy还将邀请来自不同行业的设计师和利益相关者共同创建未来的应用程序。最终，它预期并促进一个更健康，可持续，以自然为基础的城市景观。
