Dose-dependent duality: Extracellular vesicles shift from metabolic facilitators to cytotoxic effectors during anaerobic denitrification.
Extracellular vesicles (EVs) mediate critical intercellular interactions, yet their special functions in anaerobic denitrification process remain poorly understood. Utilizing the model denitrifier Pseudomonas aeruginosa PAO1, we investigated how environmental oxygen and nitrate gradients reprogram vesicular cargo and f...
