Abstract
Cyanide is a toxic compound that causes poisoning through inhalation, ingestion, or skin absorption. Due to its great affinity with metals, it is widely used as leaching for gold recovery. Cyanide is a weak acid; its dissociation constant is 9.22 at 25°C. This characteristic limits its bioremediation since it must necessarily be done at a pH greater than 9 to avoid its volatilization, and…
