Summary:
In this work the aerobic degradation of thiocyanates on a syntlietic substrate by means of selected single strains of bacteria and by mixed cultures composed from these strains is presented. By controlling the activity of single strains of bacteria it was confirmed that all strains show the capability of degradation of thiocyanate into NH₄⁺ and NO₃^-, respectively. The mixed cultures of bacteria exhibited in waste water of the Bakar cokery (Croatia) the capability of degradation thiocyanate to ammonium and then to nitrate.
