[Destruction of hexamethylenediamine by a Bacillus subtilis culture in a medium with clay minerals].

The object of this work was to study the effect of clay minerals of the montmorillonite group on the oxidative and destructive activity of Bacillus subtilis 21/3 utilizing hexamethylene diamine (HMD) in metabolic processes. HMD destruction by the culture accelerated when clay minerals were added to the chemically defined medium. The respiration activity of Bac. subtilis 21/3 was studied, and the rate of HMD oxidation was found to increase in the presence of montmorillonite.
