Evidence of hydrolytic route for anaerobic cyanide degradation.

Anaerobic Biodegradation of Cyanide Under

Biological Cyanide Degradation

Cyanide heap leaching is the predominant technology used in processing low-grade gold ores. During closure of a heap leach operation, residual cyanide must be removed from the process and waste solutions, as well as the heap. Biological cyanide oxidation is a proven, economical technology for destroying cyanide in process and waste waters and spent heaps. The use of biological cyanide degradati...

MIRAgel: hydrolytic degradation and long-term observations.

OBJECTIVE To analyze long-term complications of hydrogel (MIRAgel; MIRA Inc, Waltham, Mass) explants. DESIGN Institutional clinical study of a retrospective, interventional case series of patients. We included 415 patients with complete reattachment of the retina 6 months after surgery and up-to-date follow-up. Patients underwent ophthalmological examination at each visit (mean follow-up, 187...

Packed bed reactor for degradation of simulated cyanide-containing wastewater

The discharge of cyanide-containing effluents into the environment contaminates water bodies and soil. Effective methods of treatment which can detoxify cyanide are the need of the hour. The aim of the present study is to develop a bioreactor for complete degradation of cyanide using immobilized cells of Serratia marcescens RL2b. Alginate-entrapped cells of S. marcescens RL2b were used for comp...
