The effect of concentration of N,N-Bis(3-aminepropyl)dodecylamine (APDA) used in disinfectants (Lonzabac) on the kinetics of denitrification and desulfurication processes proceeding with the use of Bacillus licheniformis and Desulfotomaculum ruminis bacteria, was studied.
The kinetic equation for denitrification in a medium containing the microbiocide tested was derived, the parameters of the process were calculated and the toxicity limits of APDA were established. The latter are of importance when considering means for environment protection against APDA effect on the nitrogen and sulphur cycles.
