Nature Water, Published online: 04 June 2026; doi:10.1038/s44221-026-00654-5 Low temperature limits anaerobic ammonium oxidation (anammox) activity. Now a low-crystallinity covalent organic framework-based photoelectron injection strategy restores intracellular ATP and cold shock protein-mediated mRNA stability, enabling efficient anammox activity at 4 °C.
Cold shock protein-mediated proteostasis in low-crystallinity COF–anammox biohybrids enables extreme-low-temperature nitrogen removal
