Elimination of Cyanide by native bacterial strain

Cyanide and combinations dependent on it are considered contaminants of sewage in differentindustries, such as photography, pharmacy, electrotyping, gilding, and especially mines, so its elimination is ofspecial importance. There are three methods of purifying sewage containing cyanide: physical, chemical, andbiological. The biological method is more cost-effective than the other methods. In this research, the capabilityof eliminating cyanide is considered by a biological strain isolated from the Sangan mine. This strain couldeliminate ۵۳% of the cyanide in the medium with an alkaline pH at ۳۰ ۰C after ۷۲ hours.
