Direct interspecies electron transfer (DIET) is essential for maintaining the function and stability of anaerobic microbial consortia. However, only limited natural DIET modes have been identified engineering remains highly challenging. In this study, an unnatural between Shewanella oneidensis MR-1 (SO, donating partner) Rhodopseudomonas palustris (RP, accepting was artificially established by a facile living cell-cell click chemistry strategy. By introducing alkyne- or azide-modified monosaccharides onto cell outer surface target species, precise covalent connections different species in high proximity were realized through fast reaction. Remarkably, upon connection, C-type cytochromes mediated SO RP achieved identified, although never naturally. Moreover, connection directly shifted H

Abstract Plant chloroplasts have a highly compartmentalized interior, essential for executing photocatalytic functions. However, the construction of reaction compartment similar to in inorganic–biological hybrid systems (IBS) has not been reported. Drawing inspiration from chloroplast and phenomenon liquid–liquid phase separation, herein, new strategy is first developed constructing subcellular system through separation technology living cells. Photosensitizers vivo expressed hydrogenases are designed coassemble within cell create compartments synergetic photocatalysis. This compartmentalization facilitates efficient electron transfer light energy utilization, resulting effective H 2 production. The (HM/IBSCS) exhibits nearly 87‐fold increase production compared bare bacteria/hybrid system.
