Abstract Ammonia-incubated cyanobacteria liberated H2O2, accumulated hydroxylamine compounds and nitrite and catalyzed dismutation of hydroxylamine as well as oxidations of ammonia, glutamine, and oximes. Ethyl acetohydroximate-adapted Phormidium released excess H2O2 and phototrophically metabolized the oxime via hydrolysis and dismutation to nitrite and ammonia, which were co nsumed by nitrite reductase and glutamine synthetase. Added ammonia stimulated H2O2 production and oxime metabolism via glutamate dehydrogenase pathway.
