Abstract Stone samples from corroding historical buildings in Germany released NO in significant amounts during oxidation of ammonium to nitrate. Nitrite intermediately accumulated to low concentrations. Nitrification and NO release were detectable only in stones with neutral pH. Addition of nitrapyrin inhibited both ammonium oxidation and NO production. NO was produced in stone samples containing Nitrosomonas or Nitrosovibrio, but was not produced in samples containing only Nitrobacter. Addition of nitrite stimulated NO production in autoclaved stone samples significantly only if dried to 〈 2% water content, or in acidic stone samples. In moist neutral stones, NO production was only slightly stimulated by nitrite giving less than about 8% of the NO production observed under nitrifying conditions. Most of the NO production by corroding building stones was apparently due to ammonium-oxidizing nitrifiers.
