Studying some characteristics of cyanide destructors for the purpose of decontamination of cyanide-containing waste

Abstract

The subject of article is about isolation and study of endemic cyanide-resistant strain on the Madneuli mine, for further microbiological decontamination of cyanide-containing waste of the gold mining company. In the result of performed studies, for the first time in Georgia, two active cyanide-destructor stains were isolated from the liquid and solid objects contaminated with industrial cyanides: The strain #5 Bac.cyanooxidans and #12 Bac.subtilis. In the result of performed works, in laboratory conditions, in the mode of serial passage, on model solutions, some characteristics of development of cyanide-destructor microorganisms in the process of cyanide-destruction were determined. Nutrient is an impact of content, impact of the bacterial mass on the process of destruction, cyanide destruction characteristics of specific strains and their association.
