Cyanide degradation by pseudomonas pseudoalcaligenes strain W2 Isolated from mining effluent

Cyanide is highly toxic to the living organisms as it inhibits respiration system in the cell mitochondria. Cyanide is commonly used in gold extraction process and its discharge into the environment not only causes pollution but it also brings harm to the surrounding population. Chemical treatment i...
