| Abstract: | Summary A fast and simple micro-method for total nitrogen analysis in complex fermentation media is presented. Samples containing up to 50 ug nitrogen are digested in tubes with sodium selenite (in sulphuric-phosphoric mixture) plus hydrogen peroxide during one hour at 380°C. Ammonium liberated is measured without extraction by Berthelot colorimetric reaction. |
