A device comprising at least one electrode and at least one cell such as Anabaena variabilis cyanobacteria disposed on said electrode for producing ammonia. A layer of polymer, such as ion exchange polymer, can be used to help immobilize the cells. Whole cells or partially disrupted cells can be used. A method and a system for producing ammonia, comprising contacting at least one cyanobacteria such as Anabaena variabilis cyanobacteria with a media with an electrochemical perturbation is disclosed. The potential enhances ammonia production.
