title: [Determining the level of total nitrogen in wastes from the microbiological industry].
abstract: Optimization of the Kjeldahl method for determination of total nitrogen in the objects of microbial synthesis was performed in regard to biomass of the benzylpenicillin-producing culture, activated sludge and certain organic compounds. Mathematical processing of the data was carried out, which showed that the difference in the mean values for the five tested conditions of mineralization was insignificant. The method is useful in assaying the final and intermediate products as well as the waste in biotechnological production.
